Mid-2012 RMBPro 10.9.4: Is it possible to switch between graphic cards? Activity monitor shows the high perf card always active even through no running apps need it.

How does one switch between graphics cards on a RMB Pro that has both a regular and high performance card installed?

There's no control built into OS X to manually switch between them (that I know of). But in your Energy Saver preferences, there is setting called Automatic Graphics Switching that will either keep the discrete GPU on all the time, or automatically switch it off when not in use. Do you already have this preference turned on?
It might keep the high performance graphics card on if it's plugged into AC power, since there is no battery life penalty in that case.

My MacBook Pro (Retina, Mid 2012) is too slow after installing Yosemite version 10.10.1. All programs take for ever to load especially Safari and even chrome. I regret upgrading to yosemite, it was all fine with Maverick. Any suggestions ? ThankYou

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Is it possible to upgrade the graphics card on a mid 2012 MacBook Pro? And is it possible to upgrade the RAM without voiding the warranty?

Hi I was wondering if it is possible to upgrade the graphics card on a MacBook Pro and the RAM without voiding the warranty? I have a gt 650m in my MacBook Pro, non retina, and to me, its not enough power for me, so i was looking around, and I found a retailer that would give me a nvidia gtx 660m for a decent price. Also, the ram needs to be at least 12gbs, to ensure that my computer would run fast.
If you can help, please tell me,
Thankyou.

No, the video card cannot be exchanged - you have a pretty decent GPU there; not sure why you'd want to switch it out. You can upgrade the RAM to a maximum of 16GBs. Apple recommends upgrading in matching pairs, so I don't really think I'd try 4GB and 8GB stick.
Both Crucial and OWC have memory available for the new Macs. Both are reputable dealers and know Macs well and I would only buy from these sources (and I would buy Crucial, were it me).
Although your Mac didn't come with a users manual outlining the installation of the additional RAM, you can download the late 2011 model users guide as the models themselves are almost identical.
Good luck - write back with any questions.

The trackpad of my 13" macbook pro (mid 2012) has geen going nuts for about a week now. It randomly clicks and drags the cursor to all places on screen, it randomly clicks, selects and swipes. Have tried spm reset and pressure on whole trackpad. Help?!

It goes nuts for hours and the next day it acts completely fine. My macbook is impossible to work with when the problem is active; it randomly clicks, drags, selects and even selects words (in a yellow colour) to come up with latin(?!) translations.
Ive tried the reset (option+cmd+r+p) and it seemed to work at first but now it doesnt seem to have any effect whatsoever.
Also tried to apply pressure to the entire surface of the trackpad or just the top corners; no effect whatsoever.
It's been quite an expensive purchase for a young student like me and i've really enioyed it until last week.
I'd be relieved if someone came up with a solution; especially since its warranty has expired for half a year now.

Hi there Bram3,

Macbook Pro mid 2012 starting to lag when running more than one program.

Firstly mah specs :
Retina, Mid 2012
2.3 GHz Intel Core i7
8gb 1600 MHz DDR3
NVIDIA GeForce GT 650M / Intel HD 4000
OS X 10.8.4 (12E55)
So, i bought this macbook about a year and a month ago and since i bought it everything has run fine, it has always been fast and smooth, until around 2 months ago when it started getting a little laggy in handling more than one program being open. Before this i was able to run Photoshop, Cinema 4D, Second Life and Chrome all at once and recieved no speed decrease what so ever. So i figured that it must just have been a little clogged up maybe, honestly wasnt sure but tried clearing cache, tried freeing up memory with some of the mac memory management tools from the App Store and non of these worked so in the end i backed up what was important and wiped the HD and re installed the OS. Annoyingly i am still having problems, if i have Photoshop open and i am surfing chrome it lags on scrolling web pages or loading links. If i have Second Life open i seem to lag with more than 3 players around me quite badly, even if i put Second Life onto its lowest Graphic Settings i still lag where as before i had this issue i could run it on its highest Graphic Settings and recieve little to no lag what so ever. This happens for most programs that used to run smoothly, if i now open Cinema 4D and try anything else.....the system slows down.
I COULD take this to the apple store and genuis bar and ask them to have a look at it HOWEVER i am back at Uni in 2 weeks and i need the macbook for my studies as i am currently working on a summer project and need it for research, can any of you Mac Wonders out there suggest anything else for me to try. I have checked the HD and it says its not failing and is verified and found no issues with the partition.

First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
Otherwise, take the steps below when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

Just bought a mid 2012 13 in macbook pro. Battery life is only 3 hours. Thoughts?

Just bought a mid 2012 13 in macbook pro. Battery life is only 3 hours. I was under the impression that it would last 7 hours. This is with normal internet browsing and text editing. my brightness is not all the up and bluetooth is off. Thoughts?

im having the same problems, bought my 13" MacBook Pro last week and the battery is terrible on it, but i googled it and a lot of other people are having the same issues

Macbook pro retina 15 mid-2012 display problem : solution :)

Well. This topic is not really a question, I hope this could be a solution for both users and Apple. Its free, but if Apple wants to offer me a full options Mac Pro, or hire me as consultant we can discuss ^^
The story is long, but is worth. Sorry in advance for my swissy english. I hope you'll enjoy.
As many of retina mid-2012 owners (and perhaps other versions) I encountered the symptom of my machine crashing more and more frequently (from once per week to more times per day). Crash usually with a message of "read error" or some display related crash dumps, often linked to the switching of graphic card (integrated<->dedicated).
For a long times a suspected some burnt chip (because of using 1-3 external screen all the day) and seeing istatmenu with crazy temperatures of 90-105°C. I was disappointed because of the evolving symptom (crashes more and more frequent and sometimes no display at power on)
It took me ages to discover what exactly did my MBPR crash, as it was crashing "randomly" for me. Sometimes after crashing, hard shutdown and restart, it wouldn't display or even power on the backlight, for one hour or one day and suddenly it would display again !!
I tried all the solutions found here and there including replacing the thermal paste, smc or pram reset -> no luck.
I took it to my local Apple provider and I was told I would have to change the motherboard. An expensive operation, since the warranty was expired by 2-3 months.
So I bought a 13 inchs retina as replacement and continued to diagnose my 15 inchs in parallel.
I discovered that it would crash if I bend it : Power on, one hand on each side applying a light bend in the two directions made my MBPR crash. So suddenly the problem wasn't random anymore. Mouhahahaha. This could be motherboard or chip related (de-soldered solderings here or there), or case related. Let's hope the problem's not mobo related.
I opened the case and tried to see in the dark if I could see a mini lightning when bending (because of a bad ground somewhere). -> No luck
So I tried to put paper here and there to try to locate the potential bad ground. Booting, bending, hard shutdowning, papering, booting, bending,...
And suddenly the darkness became light : If I put a paper at the right place, my MBPR will resist to the bend test. Was my mobo alive, and was this nightmare only a progressive bad ground ? Yes.
Here me good : the progressive symptom of random crashing of my MBPR (which I imputed for a long time to an old chip since the symptom was the same under windows 7 bootcamp + because of the graphic switching behaviour) was in fact only a bad contact at a very given place.
The very given place (my diagnose and my solution) ?
The screws of the left's fan (thunderbolt's side) or/and the fan case itself are screwed through the motherboard. For a reason (temperature, mecanic constraints or corrosion) this stuff entered in contact with each other, the redox gained the near electronic motherboard tracks (especially the thunderbolts one I guess).
Proof :
If I put a piece of paper between the motherboard and the case, I can bend my MBPR without it to crash and use it as before (except for external screens).
My diagnose :
once the material of the screw/fan case/motherboard track enter in direct contact, there is a corrosion effect that affects more and more the neighboor.
Here is a pic of my repair :
I can now :
play hours in windows 7 bootcamp
switch between graphic cards with gfxcardstatus (even with a playing itunes animation)
sleep and wake up with integrated or dedicated graphics
I can't :
connect a screen through thunderbolt since it activates the corosionned part of my MBPR, so it will work for a period of time but will assure me that a crash is awaiting (perhaps after a wake up or randomly from this time)
I'm confident that this problem is conceptual and that a big part of 15 inches retina mobo's exchanges are due to this question.
Hope this helps
Kisses from Switzerland

I tried to diagnose this mid 2012 retina 15 inchs for a couple of month now. With a very similar symptom of a lot of people :
some that exchanged the motherboard more times and experienced again the same freezes / shutdown again
some that installed mavericks by believing it workarounded the problem (but majority also says after a while that actually the problem was only differently reproduceable)
some hoping Apple to release a sowtware fix for that or a recall of the concerned machines
I now think to have isolated one of the cause of such symptoms. At beginning I thought that the fan electric insulation had worked but actually not.
Solution for me :
open the under case
dismount a bit the two fans
insert paper bands under the motherboard (between the black bottom and the motherboard, I used ~120gr/m2 paper and cut it into bands of 10-13cm by 2-3cm).
I would have dismounted the motherboard if I had the right screwdriver, but this seemed to be a too long/hard work, so I went into this idea that my motherboard was ok and that the problem was only caused by a supposed short-circuit under the motherboard.
My thoughts :
The more big the hole in the black tape under the motherboard, the more frequent the freezes / shutdown due to a short circuit (electronics grounded at the false place because of the mobo entering in contact with a grounded metal part through the black tape)
I also thinks this short circuit is more dedicated graphics linked than integrated and that this is the reason why the symptom persists or reappear even after multiple motherboard exchanges for a lot of people and the reason some people use their machine with forced integrated graphics
This solution should apply as self doable for a lot of people
If I should bet, I think that the black insulating tape under the keyboard is scratched by the time (mecanic constraints on the chassis) by some mobo component until a false contact is created through the insulating tape
I can now (mid-2012 retina 15 inchs I7 8go 256go, osx 10.10.2) :
run firefox or VLC with integrated or dedicated graphicssleep/wake with integraded or dedicated graphics (forced or auto-switching) with such programs runningrun multiple screens (2x TB + HDMI at the same time), sleep the machine, unplugging 1 of the 3 screens during the sleep, wake the machine + bending the machine during the process without it to crash. \o/
The goal of this post is to share this amazing experience with both Apple and the users facing such a problem.
Problem solved without motherboard exchange and with a quite easy workaround

After sleeping my macbook pro 15.4" mid 2012 model for overnight and pass 24 hours time, on wake -- the dock background is white for a few seconds and then it turns back to normal color. . .

After sleeping MacBook Pro 15.4" mid 2012 model (running Mac OS X 10.10.2 Yosemite) for overnight and pass 24 hours time, upon wake from sleep-- the dock background is white for a few seconds and then it turns back to the normal color.
Is this normal? Should I be worried? Is my GPU defective?

Thanks to all in advanced.

It doesn't happen all the time but sometimes and i tried zapping the PRAM and it still happens!

WiFi goes blind on 10.9 for mid 2012 MBA

Hello folks, hello experts,
this is going to be another thread with issue seen on previous versions of OS X.
I have bought a brand new in a box MacBook Air 11 a week ago, old stock however, mid 2012. It was just a day or two after 10.9 Mavericks came out, so the first thing I did was going to AppStore (over WiFi), made the FW check for the SSD, applied the Update, then (from this part over Ethernet) Upgrade from 10.7.5 to 10.8.5. Right after that Mavericks 10.9.
At home I have added my WiFi network and started to using the thing. Then following issue came out:
After waking from sleep, the WiFi is searching for networks but cannot see ANY.
What I did/tried:
All the possible old tricks (stupid or not) I could find:
- waking the MBA with power button
- keep the Bluetooth turned off
- deleted all preffered networks
- deleted Keychain entries
- moving system cofiguration files !
(- aks about others, I might have forgotten some...)
Nothing helped.
From the On/Off tricks also all possible were tried:
- Wifi
- Sign out
- Restart
- Power
Since the thing was new I had no problem to make fresh new install of 10.9 Mavericks. I did. Did not helped.
The issue is still here.
I have brought the MBA back to the shop, it went to authorized service. They have tried for one day (not sure, may be less) but they could not repeat the issue. They made Apple HW test, all OK. We agreed, when it comes back, they will try longer.
Symptoms:
- When MBA goes to sleep - seems like only the "deeper sleep" with disc unplugged - and then wakes does not see any available networks. WiFi is On and searching. Produces no error, behaves like everything is OK, just there are no networks around.
- Probably it should be not an issue of my router as the MBA does not see any network, not even the ca. 8 newtorks from my neighbours
- There is no 100% cure, the blindness seems to go away randomly. I mean, sometimes one trick helps, sometimes none (On/Off: WiFi, Sign Out, Restart, Power). I cannot tell why it then goes all right.
- My network (from which it goes to sleep) is on TP-LINK router with excellent signal, set up as not broadcasting SSID, Auto channel, WPA2, Auto bgn. I tried using also broadcasting SSID, fixed channel, fixed N.
- I cannot tell if it has a connection to a user, seems like not. There are 2: Administrator and Standard. Looks like the issue might relevant for both. I could update here.
- It does not matter if the MBA is on battery or plugged in.
- This issue never occured on any other device before (Windows PCs, Andorid devices, iPhone, MacBook 2009 - this one was not tested on my network after 10.9 update yet).
Other information:
- All possible updates for 10.9 are installed, including the one from this week.
- No accounts are connected (no mail, no cloud).
- From the installed software, there is TeamViewerQS and Skype - this one was and is not connected, Chrome web browser.
- FireWall is turned on.

Any other required information or log files could be supplied within my skills (and your navigation), just ask for them.
My personal humble opinion told/tells me follwing:
- At first I thought it was SW issue. That is why I did the clean re-install.
- Afterwards it looked like a HW problem. That is why it went to AD/S.
- Since all HW tests passed OK, I think again it could be only SW issue. The question is now, is it a WiFi firmware issue or OS X 10.9 issue ? Or both...
Any input will be welcomed and highly appreciated. Thank you all in advance !

Miaco,
I have the same issue and it behaves as you say. I did the SMC reset and it solved the provlem...
...for a few days. Now the same behavior is back :-( I did again an SMC reset and also a PRAM reset but it did not help.
I was again in contact with Apple chat and he also recommended to play with the locations, creating a new one. I haven't tested that, but will give it a try.
The next thing if this does not help, was to to make a new installation via "archive - install". I will see...but it is very annoying because under Moutain Lion everything was fine. I'm not really motivated to make a new Installation since this is very time consuming....:-(
So if I were you, give it a try to reset SMC, PRAM and play with locations...
reset SMC:

Macbook Pro (mid 2012) is slow to start up when trying to wake up

Ok, this is a strange question that I haven't been able to find a good answer for. The issue at hand is that when I close my laptop lid, like for overnight or other long duration with no use, and I leave the power cord connected, when I try to open it it seems to take an inordinate amount of time to restart.
Conversely, if I do not have the power cord plugged in, it starts up nice and fast. And by this I mean when I open the lid, the screen shows the desktop right away, trackpad and keyboard are functioning, and the wireless starts up and begins looking for my wifi. I apologize, I can't remember off-hand if I have to log in. If I do, then it just starts up right away after log in, no noticeable issues.
Now, when I have the laptop plugged in, when I open it to start using it, I have to log in (which is fine, that's what I prefer), but the log in screen is pretty weird looking.
It seems like my login icon should be centered, or there should be the guest account login to the right or something. I don't know if this is indicative of the issue, but just something I noticed. Once I login from this it takes a couple minutes to get to where I can actually use the keyboard or trackpad. What is puzzling is why the behavior is different based on if the laptop had been plugged in or not.
I have tried resetting the PRAM, and I even tried entering a longer PMSET to extend when the hibernation would kick in (I had tried a setting of 24 hours, I know it converts to seconds, I didn't set it to 24 seconds ) but that didn't help so I set it back to the default. I also tried shutting off all of my startup programs like Dropbox, Google Drive, etc just to make sure I wasn't auto starting a memory hog, but that didn't seem to do the trick.
I'm using:
OSX 10.10.1
Macbook Pro (13 Inch, Mid 2012)
2.9 i7 processor
8 GB RAM
Thanks in advance!
Anyway, it's not the worst thing in the world, it's just super inconvenient.

I have a macbook pro from the exact same time (since mid-2012) and i have the exact same problem; takes about 5 mins to wake up fully after it's been plugged into the AC adapter for long time. I have also tried resetting the PRAM and entering a longer PMSET, but neither have worked.
One thing I should add is that (sometimes) while I am waiting for the keyboard to start working, but the screen itself is on and I can see the desktop, I get a message saying the bluetooth can't "find" or "connect" to my keyboard. I wonder if it has less to do with the computer being slow to wake up and more to do with the bluetooth. Is that even possible?
Anyway, I have been trying to figure this out for years, and nothing has so far worked. Really hoping someone can help solve it.

Late 2013 Macbook Pro Retina 15' will not boot an external disk from a Mid-2012 MAcbook Pro. What should I do?

In order to simplify moving all my files from the previous mid-2012 macbook pro 15' when moving to my new late-2013 macbook pro, i superdup-ed the full hard-disk to an external ssd. Unfortunatelly the new mac resuses to boot from this external disk (i get the grey disk with a line over it). The external disk works just fine so if I boot the new mac from its internal SSD I can read/write the external disk without problems.
Old OS X is 10.9 as is the OS on the new mac.
What I need to do is to boot the new mac from the external ssd, use the same superduper to copy the external content onto the internal ssd.
How can I solve this issue?

Welcome to Apple Support Communities
If you made a backup of your files with SuperDuper, use Migration Assistant (in /Applications/Utilities) to transfer your files from the external drive > http://pondini.org/OSX/MigrateLion.html It will create a new user account with the transferred files, so you may want to merge both user accounts > https://discussions.apple.com/docs/DOC-5472
The Late 2013 MacBook Pro uses a special OS X Mavericks version which makes OS X compatible with it, and older OS X versions do not work with it. That's the reason why you cannot start up from the external drive created from the Mid 2012 MacBook Pro

Mountain Lion 1.8.2 update made my dual monitor stop working on Mac Pro mid 2012

Just done Apple's update for Mac OS X Mountain Lion to 1.8.2 and after rebooting my dual monitor stopped working.
If I go on preferences -> Displays it shows me only one of my two monitors, even if I invert the connections the 2nd monitor doesn't shows up and there seems no way to enable it again.
Any suggestion?
P.S. I already tried to set from "Best for display" to "Scaled", but after rebooting Mountain Lion 1.8.2 reset it to "Best for display"

Ok,
did some extra test here, but first of all my configuration:
Mac Pro (Mid 2012) with ATI Radeon HD 5870 1GB.
2 LCD 24" Wide-screen (1st monitor Hyundai W240D and 2nd Monitor HP w2448hc), both LCD worked perfectly until reboot after installing OS X 1.8.2
After reboot only the 1st monitor wored fine, the 2nd not even listed, so tried to invert cable connections on the 2 miniports on the ATI video card, but nothing changed, still only the 1st monitor working.
Did a second test, disconnected the 1st monitor and connected ONLY the 2nd and now the second works fine.
Tried to connect 2nd monitor on a different miniport, and i still works fine.
Updated my MacBook Pro to 1.8.2 (it as an nVidia card) and connected my 2nd monitor to it and everything works fine, both the laptop LCD and my HP LCD are working fine.
So it looks like Apple screwed up the ATI driver on the latest 1.8.2, now only ONE miniport is active.
To all users with the same Mac Pro configuration: hold to update to Mountain Lion 1.8.2 until Apple fix this driver issue.
More info are on the Console output, so will have to contact Apple on-line support to signal this bug.

Mid-2012 display flickers

I've had my Macbook Pro Mid-2012 for just over a year now and never really experienced any problems until recently.
The screen gets horizontal lines running across it, which flicker. Sometimes it won't do it for ages, and, when it does, it barely happens, then sometimes it's really frequent.
Has anyone else had this issue? I've been searching online all day and can't find a solution. Apple support asked me to reset the SMC but that hasn't fixed the issue.

A pro forum user chimed in with this info:
Vertical Lines - Bad LCD or LED Screen
Dim Screen - Bad Inverter, Backlight, or (unlikely) Motherboard
Garbage On Screen (symbols) - Bad Video Card
Horizontal Lines - Bad LCD or LED Screen or Video Card
White Screen - Video Cable not connected, but inverter cable is still connected
Black Screen (No signal) - Video cable (Motherboard Side) not connected or (unlikely) both video and inverter cable not connected
Partial Black Screen - Bad Screen or Video Card
In other words, it's probably either a bad LCD or LED screen, video card, or loose connection. Definitely related to hardware, not software. Hopefully, someone with more expertise can narrow things down.

Mid 2012 display hinge loose (oh no not again)

Just purchased 7 of the brand new mid-2012 13" MBA's. I've noticed with all of them that when I use the protective case I've been using for more than a year that the display cannot hold itself up once I open the screen to approxiamtely 100deg-- it falls all the way back to its wide open stance ~135 deg.
Anybody else with the new MBA experiencing this?

I just bought MBA2013, it has the same problem you had.
It has past an year after you post about this matter, I wonder how you treat it after then.
I am thinking to replace it.

What's The Best App to defrag MB Pro (13inch-Mid 2012) 10.8 ?

What's The Best App to Defrag a MacBook Pro (13inch -Mid 2012) 10.8 ?

Do you access these files frequently or are they just stored on the drive? If the latter they do not require defragmenting.
If your computer is slow that may have nothing to do with fragmentation. You would need a drive nearly 100 % full of data you regularly access before you would see signs of slowdown due to fragmentation. Were that the case you have more to worry about than defragmenting the drive.
See the following suggestions:
Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with a visit to: OS X Maintenance - MacAttorney.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Data Backup
3. Deja Vu
4. SuperDuper!
5. SyncTwoFolders
6. Synk Pro
7. Synk Standard
8. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.

Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.
