Macbook Pro Retina. Decimal HiDPI or set 1920x1200 resolution.

I'm running Arch on a 2013 Macbook Pro 13" with Retina display and Gnome. At the moment I am using the full resolution 2560x1600 and have scaled the fonts up a bit which is ok for now.
But I would really like to either HiDPI scale it to 1920x1200 (1.34 scaled) or I would just like to set the resolution to 1920x1200.
Option #1 (HiDPI Scaling)
Gnome doesn't seem to have an option to scale decimally it is either on for off, if anyone knows how to scale the Gnome Shell decimally this would be my preferred solution to downscale to 1920x1200. From what I have found so far this doesn't seem to be possible.
Option #2 (Set resolution to 1920x1200)
This one I thought would be easier, I picked 1920x1200 because it 16:10 like the screen. However, it is not listed as a selectable resolution so I added it with xrandr but when I set it either using the display property in Gnome or using
xrandr --output eDP1 --mode 1920x1200_60.00
it flickers for a bit then jumps back to 2560x1600. Any ideas why?
xrandr output
Screen 0: minimum 8 x 8, current 2560 x 1600, maximum 32767 x 32767

I have an apple Macbook pro Retina. I was looking at resolutions and by accident clicked on 780 and now I can not get back into resolutions to set it back top 1080p? Any suggestions how to do this?

I can not reset my resolution back to 1080p after clicking on 780 by mistake. My laptop will not go back to reolutions?

Have you tried restarting and then try to change it again?
Do a backup.
Quit the application.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Then go to Preferences/com.apple.systempreferences.plist. Move the .plist to your desktop.
Restart, open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer one.
Thanks to leonie for some information contained in this.

Hello, I have a Macbook pro retina-2013. About Mavericks I could set my 4K monitor via HDMI on 2560x1440. This I can not get through at Yosemite. Can someone help me there?

They really pushed that it would all work great! Has anyone had the same struggle? Are there any step-by-step instructions to get linked up?
Call Verizon's wireless tech support & explain your problem to them. They will provide "step-by-step" instructions over the phone.
Take notes too!
TIP: If you do call & don't want to go through all those darn promps, when you initially call, just don't say anything. The automatic voice will then say, "will connect you to a service rep."

Impossible to boot MacBook Pro Retina ! impossible to start in single user mode, Openfirmware password set, but safari works!

I have got a Macbook pro retina.
I have done 2 partitions on the SSD drive. 1 for the OS and 1 for the user (with a kind of ln -s /Home/myself /Volume/Part2/myself
I was watching a movie (with VLC) in full screen for a while and I wanted to escape. Impossible, and impossible to reboot.
When I start, I have a directory with a question mark.
I have a Open firmware passwords set (that I remember).
I cannot reset PRAM. (I can not change the RAM amount inside the commuter as this is a retina model)
I cannot start in verbose mode.
I can choose a disk to boot. I see only the OS drive and not the user partition, and no 'recovery partition'. It seems that i need to do a fsck -yff on the user partition but how ?
I can start the OS partition, and i can choose 'guess' or 'myself'. If i choose myself, I have an error message :'there is a error, the session can not start'. If I start with the guess account, I restart, and then I can browse the internet with safari (this is how I am writing this text!)
=> How can i repair the partition ? (open a terminal, boot in single user mode ...?)
best regards.

Actually, the recovery partition was there, but was not shown as my user partition. I have seen that reseting the PRAM and changing the ram could remove the open firemware password. So i have turn the computer on until the battery was empty. Then I boot about 20 times, and unplug the power supply after few seconds at different step of the booting pricess. At last, the screen default resolution when booting changed, I undertood that i succeeded, and I was able to enter.
Then I boot in single user mode, removed the open firmware password, activated the root user, and everything was fine now !

MacBook Pro retina 13" (late 2013, Haswell) why is the highest resolution rendered in 3360x2100, which the system obviously can't handle?!

Hey Apple and Apple users,
I just recently switched from an MacBook Air (mid 2013) to the new Haswell MacBook Pro retina 13" (late 2013 model).
The main reason to do so was the better screen and the option to run higher scaled resolutions, as advertised.
I was willing to trade in the Air's low weight, smaller formfactor and the extra batterylife for the better screen.
When it comes to resolutions:
1280x800 is just a joke nowadays, why is the MacBook Pro still based on it? 13" and 1440x900 work quite fine...see MacBook Air.
1440x900 is okay in everyday life situations, but sometimes you just need "more space" as the third scaling option calls it as well in the display-settings.
1680x1050 on 13" can sometimes be challenging, but it is really fine if you need to work and have a lot UI elements to deal with (Photoshop etc.)
So 1680x1050 scaled on the 2560x1600 screen would be my daily driver for work. So I expected a scaling factor of "1.5238..." (2560/1680) will be used most of the time.
Frankly spoken...I am really disappointed by the 13" retina MacBook Pro and the way OS X Mavericks is handling the scaling.
It obiously works well and responsive with the 1280x800 non-scaling resolution ("best for retina, scaling factor 2: 1280 --> 2560).
Is still "okay-snappy" at 1440x900 (scaling factor 1.777...: 1440 --> 2560).
But it totally breaks down at 1680x1050 (scaling factor 1.523...: 1680 --> 2560).
I use "Mission Control" all the time and it is stuttering and slow...overall a sluggish and unbearable experience.
The same goes for Desktop-Switching by swiping the screens or resizing and moving windows and files around.
So I was wondering why...and then I noticed that when taking a screenshot of my entire screen (CMD + 3) the image size of the screenshot was 3360x2100 and not the expected 2560x1600.
This means Mavericks is not scaling the UI with the appropriate factor (see above). For retina MacBooks it ist simply rendering one pixel of the classic, non-retina Interface in now 4 pixels (2x2) and sending this straight to the screen, which then "scales" it down to the resolution it is able to display.
Why is this bothering me? – Because the machine has to do a lot more work to render the higher resolution that can't even be displayed, due to the screens limitations.
2560x1600 = 4096000 pixels = 100%
3360x2100 = 7056000 pixels = 172%
This means the MacBook has to render 72% more information than actually can be displayed on the built-in screen and are just lost.
Of course this makes the overall UI feel sluggish and idly! Especially with the not that performant Intel Iris IGP and no dedicated graphics card.
All this extra "rendering" just results in a worse battery life due to the extra work that the graphics card and CPU have to do.
First, Apple...are you serious about this?
What can we do about this?
Is there a way to have this properly scaled?
Thanks in advance to everyone.

Okay...I thought deeply about this issue.
Even looking into ways to maybe fixing this on the software side. But it occured to me that this is to deeply embedded into the system that it won't be possbile to come up with a sufficient third-party solution.taht
The problem is that there is no intermediate step inbetween "standard DPI" graphics and "HiDPI" (image-resources named "[email protected]").
But there should be one, to minimize the amount of image information that needs to be processed by the device.
This effects especially the MacBook Pro retina 13", as it has the less powerful Intel Iris IGP, when performing on the highest scaled resolution (equivalent to 1650x1080).
As well as the MacBook Pro retina 15" without a dedicated, second Graphics Unit,when performing on the highest possible scaled resolution (equivalent to 1920x1200).
Those devices don't have enough resources to handle the consequential "HiDPI" resolutions of 3360x2100 for the 13" and 3840x2400 for the 15" model.
(Comment: 3840x2400 = 9,2MP, which is more than the standard 4K resolution of 3840x2160.
I analyzed the scaling factors as follows:
Factor "2" to display 1280x800 on the 13" model and 1440x900 on the 15" model in HiDPI.
Factor "1.777..." would be required to display 1440x900 on the 2560x1600 screen of the 13" model.
Factor "1.714..." would be required to display 1650x1080 on the 2880x1800 screen of the 15" model.
Factor "1.523..." would be required to display 1650x1080 on the 2560x1600 screen of the 13" model.
Factor "1.5" would be required to display 1920x1200 on the 2800x1800 screen of the 15" model.
As all the models seem to have no problem with rendering the intermediate scaling step (1440x900 for the 13" and 1680x1050 for the 15" model) at HiDPI, hence with the scaling factor 2. There is no real need to provide the UI-elements.
But in my opinion there is a strong need for a "MidDPI" ([email protected]) intermediate step for all the UI graphic elements that wis based on the scaling factor 1.5.
This would result in the following:
13" MacBook Pro retina with 2560x1600 screen:
1280x 800 @ 2x = 2560x1600 (no surplus, native screen resolution)
1440x 900 @ 2x = 2880x1800 (the surplus of 1088000px = ~1MP can still be handled and compansated by the weak Iris IGP)
1680x1050 @ 2x = 3360x2100 (the surplus of 2960000px = ~3MP is too much for the weak Iris IGP)
NEW 1680x1050 @ 1.5x = 2520x1575 (with a small border of left=20px, bottom=13, right=20, top=12 pixels, which means ~2,2mm and ~1.3mm around the 1.5x scaled image!).
15" MacBook Pro retina with 2880x1800 screen:
1440x900 @ 2x = 2880x1800 (no surplus, native screen resolution)
1680x1050 @ 2x = 3360x2100 (the surplus of 1872000px = ~2MP can still be handled by the Iris Pro IGP)
1920x1200 @ 2x = 3840x2400 (the surplus of 4032000px = ~4MP can't be handled sufficiently by the Iris Pro IGP)
NEW 1920x1200 @ 1.5x = 2800x1800 (nu surplus, native screen resolution, no border needed!)
The big advantage is that all the graphics have already been remodeled for the HiDPI mode.
So scaling those "factor 2x" images down to "factor 1.5x" should be comparably easy!
Example:
Left: Traditional "standard DPI" icon of "all my files".
Right: "@2x.png" for the "HiDPI" modes.
Middle: "@1.5x.png" suggestions for the "MidDPI" mode; easily scaled down from the lovely HiDPI graphics.
With this simple introduction of the "MidDPI" modes a significant amount of processing power can be saved.
This not only improves battery life when driving those higher scaled resolutions, but also lets the user access those resources for what really matters: processing power for the primary job that the Mac needs to get done.
Thanks in advance.

Macbook Pro Retina 13" late 2013 lag

Hello everybody,
4 days ago i bought Macbook Pro Retina 13" late 2013. overall i like it as a first time mac user.
my problem is it feels very slow and unstable and laggy.
After some testing:
1024x640 (Larfer Text) - no lag best performance
1280x800 (Best for Retina) - some lag
1440x900 (Middle) - Some lag
1680x1050 (More space) - Lots of lag
The lag is most visible when scrolling, resizing the window, and overall performance of third party applications for example netBeans is very slow under highest resolution and even with best for retina.
But what is interesting is when i conect the macbook pro to an external tv using hdmi there is no lag, very smoth.
I have contact apple support couple of times since i get the device, i even went to the apple store genius bar., all their representative in the apple store pretended that everything is ok with the mac, but some phone representative agreed with me that i have to lower the resolution when using some applications. basically there is no solution for the lag.
i am very disappointed with this issue. I should be able to use any resolution I want without any lag.
sometimes i can not feel the fast SSD it feels like an old HDD.
I think its unacceptable to pay $1500 for a computer that doesn't work as advertised
I think i am going to return it until they find a solution
Are you experiencing this problems with your macbook pro retina

Here is my post on another Forum. My problem with the UI is now solved :
hi there,
same problem here. i had a mba 13" 2012 and wanted to switch to rmbp 13 because i need more real estate.
i sold the mba on ebay, but had a few days to compare my rmbp and mba side by side. both with exactly the same software configuration and OS Mavericks.
the mba was obviously snappier and i didn't know why.
after reading tons of threads, exchanging the rmbp one time and being frustrated i discovered this thread.
so i downloaded RDM, set the resolution to 1680x1050 (non-high-dpi!!!) and there it is, a snappy rmbp with mavericks.
(for me real estate is more import than a shiny retina thinggy, but also i don't see a bit difference between 1680 hiDPI and 1680 "normal")
i suspect the os isn't yet optimized, but i am far away from a software expert.
here is the link for RDM:

Screen Sharing issues MacBook Pro Retina

Loving my brand spanking new MacBook Pro Retina 15" running Mavericks. Display set to 1900x1200. The only thing it doesn't do, is play full screen YouTube video from my Mac Mini (2011), as soon as I put that in full screen mode on the Mini. Mouse and keyboard no longer respond, the only option is to wait untill it is finished or use the controls on the Mini. My screen sharing is set to all adaptive settings.
What I have done to do checks:
remote control MacBook Pro Retina from Mini (same settings for screen sharing, resolution on Mini is 1080p) and play full screen HD YouTube video: no issues, scaling works flawlessly;
check all network settings on both computer - no issues, both connecting full speed (400mpbs), wireless file exchange proves this;
reinstalled Mavericks both on the macbook and Mini;
removed all plists and preferences on both machines;
saved files to external HD, emptied harddrives, and clean installed Mavericks on both(!) computers
Installed all updates to december 12th 2013 (including the december screen sharing update).
All to no avail. So I figured to draw some new variables in the equasion and do some control testing.
I have done a test from an older MacBook Pro 17" (2010), display set to 1900x1200 as well. No problem at all controlling either computer. Scaling works flawlessly. Dito from an older iMac 21" running Mountain Lion. Like a charm, correctly scaling to meet the screen and network confitions.
So I figured shrinking the size of the application window on the MacBook to about 1/4 of the surface, and guess what: there she flies. Enlarging the application window on the MacBook Pro has a linear effect on the responsiveness of the screen sharing application, trying to view full screen video the Mini.
Verified this by controlling the older MacBook Pro 17" (1920x1200) from the MacBook Pro Retina 15". Confirmed that the above problems persist. Shrinking the screen again smoothens things out.
This quite definite to me, it is the screen sharing application that is not able to handle scaling on the hardware or interact with the software drivers of the Intel Iris Pro/NVidia GeForce GT750M combo. I hope this gets fixed soon!!

Setting Low Res on the apps didn't seem to help, however (as has been mentioned elsewhere) changing the display settings to non-HDPI does fix it, for GoToMeeting at least. (Also it let's you appreciate how nice the retina display is, in case you've already gotten used to it!)
You need an app for that however. SetResX from http://www.sendspace.com/file/mef6sk works well for me. To return to nice Retina/HDPI mode you have to go back to Display Preferences (and the "Show in Menu Bar" option for Display Preferences is sadly AWOL in Retina/Lion so you have to navigate through System Preferences.)

MacBook Pro Retina Thunderbolt Ethernet issues

hi Folks
I have a macbook Pro Retina 15" here, using the thunderbolt ethernet adaptor.
if i boot the machine into windows 7 with the ethernet thunderbolt adaptor plugged in, it works fine.
however if i remove it while windows 7 is loaded , and then plug it back in, it wont work until i reboot , back into windows 7.
this is using the drivers as supplied in the boot camp installation package.
I have tried this with numerous mac machines and the thunderbolt adaptor, and they all perform the same.
ie if you remove the thunderbolt adaptor , and then plug it back in, you will have to reboot the mac back into windows 7, before it works properly again.
does anyone know why this is? and is there any way around having to reboot?
thanks

So I've noticed similar behaviour on my Macbook Air. It's a slightly different set of kit, since it's connected to a Belkin Thunderbolt Express Dock (http://www.belkin.com/uk/p/P-F4U055/). I'm on my second one of these because first one went back because it kept on dropping the internet connection (sounds familiar?) - and it *might* have been occurring when waking the system from sleep (I didn't make a mental note).
Anyway the replacement was working perfectly, until today - when it's started to drop it's internet connection again, and this time I'm pretty certain that it's related to waking from sleep. The main difference now is that I *just* upgraded to Mavericks, and I wonder if the sleep problem has reared its ugly head again in the latest version of MacOS?
All in all I have to say I'm pretty disappointed with the reliability of thunderbolt & the Belkin Dock thingie. Although it should be said that a single lead from my Macbook Air to the Express Dock is simultaneously carrying: video (1920x1200), Firewire800, 3xUSB3, gigabit ethernet and sound, so I'm not that surprised this technology is prone to the odd glitch, and the cables get really warm too!
It would be great to have some solid information from Apple/Belkin about this.
Cheers, Jon

Call Apple Care.
#1 - You have 14 days from the date of purchase to return your computer with no questions asked.
#2 - You have 90 days of FREE phone tech support.
#3 - If you've purchased an AppleCare Protection Plan, your warranty last for 3 years. You can obtain AppleCare anytime up to the first year of the purchase of your computer.
Take FULL advantage of your warranty. Posting on a message board should be done as a last resort and if you are out of warranty or Apple Care has expired.

Macbook Pro retina have a network problem that I need to restart my computer before getting it's able to connect to internet

Macbook Pro Retina 15" 2012, Mountain Lion OS pre-installed.
Case 1:
It connects to WiFi home network and internet fine.
Put the machine to sleep.
Upon waking up, it can scan for my home network that it used to connect to, but either not able to connect, or even after it connects, it just can't let me access internet.
Restarting the machine can revive by getting it connects properly to internet.
Toggling the Bluetooth won't help here.
Case 2:
It connects to network using USB ethernet adapter.
Same case, everything works fine before sleep. After sleeping for some time, it's not able to connect to the internet any more unless I do a restart.
It's able to access local area network though, as I'm able to see some local network machines in my Finder window. Yes, I clicked on them and able to connect to their share folders. But just can't get through internet.
OS Problem? I'm not able to roll back to other OS, I swear I don't want to go through that painful process.
Hardware problem : WiFi card? Don't think so, because I can't get to internet even I immediately switch to USB ethernet adapter.
Hardware problem : USB ethernet? It works fine in other non-Mac machines.
There got to be something wrong in somewhere that it doesn't re-establish the connection to the internet, no matter what I do.
None of the functions in the network utility tool can help.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

My left shift key on Macbook Pro Retina (15") is behaving like the F11 key (show/hide open windows). The key behaves the same for the laptop keyboard and for an external Apple keyboard? This just started in last week after 6 months of use

My left shift key on Macbook Pro Retina (15") is behaving like the F11 key (show/hide open windows).
The left shift key behaves the same on the laptop keyboard and on an external Apple keyboard.
This just started in last week after 6 months of use. The right shift key and other keys on the keyboard all appear to work correctly.
Suggestions greatly appreciated.

I have a solution to this issue now after a discussion with Apple Support. Some where in the last few weeks, there was a change in the key that would do a Show Desktop under the Mission Control settings in the System Preferences. Even though the key sequence that was shown for the Show Desktop setting did not include the Left SHift key, by changing this first to having no key sequence and applying that and then changing it back to the F11 key, the Left SHift key issue that I was having has cleared up.
A second issue that was uncovered was that the SSD had some issues (uncovered when I ran Disk Utility using the Repair Disk key). I had to restart and use the Disk Utility through the Command R sequence to get to the stand alone Disk Utility. The SSD appears to be running better as a result as well.
Hope that this is of use to someone else in the future.

Opening and cleaning a Macbook Pro (retina 2012)

I have had my MacBook Pro retina for more than 2 years, without cleaning the insides yet
I have used it extensively, many hours every day, and there has been periods of daily smoking
Should I just order a screwdriver set (pentalobe?), open it and clean the fans etc.?
I assume warranty is already expired.
But will opening and cleaning it be complicated or risky business? I'm good with electronics, but Apple uses small and delicate screws/parts etc.
Should I use a swab, compressed air container, or will a vacuum cleaner do? (metal/plastic head; static electricity)

I would. I open up my MBPs without fear. I suggest that you place it on a large surface with a clean towel underneath. That way you can slide it around without damage and when you drop a screw, it will tend NOT to bounce away.

Yes, unless you purchased Apple care which extends it to three years.

I do not consider it risky if you use patience and a little common sense. You may also need a #00 Phillips driver and possibly a Torx driver. Check the iFixit.com web site for disassembly instructions for you model and appropriate tools. That way you will have an idea what to expect. Swabs with a non-residue electronics cleaner and compressed air are good ideas. A vacuum cleaner should be used very judiciously.
Ciao.

How can I adjust the contrast of video on my MacBook Pro Retina so they don't look like they were filmed with an old sock over the lens?

I'd like to watch movies and TV shows, downloaded from iTunes or Amazon, on my MacBook Pro Retina, but they all look like they were filmed with an old sock over the lens. Daytime sequences look muddy, and night time sequences are incomprehensible with anything but the brightest objects rendered as black. I can watch the same files on my old MacBook Air and everything looks right, but no manner of tweaking seems to let me watch movies on my new machine.
I've tried adjusting the gamma. It's a bit better when gammas is set to 1.0, but I can't seem to set a gamma less than one. I tried using the Accessibility Contrast control, but it just lowers the contrast, swallowing my desktop into the dark abyss. I tried Applecare, but they don't have a clue. I tried the Apple Store. The "genius" confirmed that it is indeed impossible to watch movies shot anywhere but in the brightest sunlight on a MacBook Pro Retina, and it isn't just my machine, but every similar model in the store. He arranged for someone who really understands color profiles to give me a call, but Apple seems to have dropped the ball on this.
Is there some tool for stretching out the darker grays in Apple video? I don't want calibration. My impression is that my display, like the dozens I checked at the Apple Store are calibrated to make all dimmer grays appear completely black. I want uncalibration so I can actually see what is going on in the movies even if something is in a light shadow or shot at night. Hollywood has lots of trained technicians who can light and shoot night scenes that are quite comprehensible. I've watched a number of such scenes on my old MacBook Air. Now, I'd like to enjoy their artistry on my MacBook Pro Retina.

http://www.ifixit.com/ has directions for do it yourself. Also look at PRAM battery instructions, as sometimes this can fix optical drive issues.
You can get external or internal drives from http://www.macsales.com/
I also suggest in the future, take care of this problem while it is still under warranty. It may have cost you nothing.

My MacBook Pro Retina's Bluetooth chipset unknown/odd login message on the login screen states Login Window Authentication Login window Name edit text has keyboard focus. In addition, the login screen is not remembering me

I have been experiencing several issues with my MacBook Pro Retina mid 2012. My MBPR is scheduled to go into the depot. However, I am wondering if anyone may be able to shed light on a few issues as this is the third "official" time my MBPR is going back for service ("one depot" trip; "one authorized" dealer; several in-store visits).
My Bluetooth is stating that the Bluetooth Chipset is Unknown (0). I also have had Bluetooth Preferences mysteriously change on me. In addition, while Bluetooth is off there are two serial modems turning on. I have turned them off, but they continue to pop up.
In addition, when I log in, my MBPR is not remembering me and my login name is not appearing on the slate-gray screen. The name and password are blank and the following message appears in the lower left hand corner. "login window authentication login window Name edit text has keyboard focus." As a side note, I am the only user. The login issue is a recent occurrence as we just totally wiped it again via a Command + R, and I don't believe I have an accessibility setting set to anything that would cause this, but wanted to check.
Should I be concerned here? Has anyone else had issues like this? I don't want to worry if I don't have to. I have had so many issues over the course of nine months. 5-6 wipes. Airport card replaced and I am about to pull my hair out if my MBPR doesn't come back worldly like clock work this time. I just can't send my days trying to get a $2300 product to work for me any longer. No idea what is wrong with it, but it is driving me insane. Cross your fingers for me and any guidance you have or thoughts would be welcomed. Thank you. EMM

WARNINGS in Console include:
[NSImage compositeToPoint:fromRect:operation:fraction:] is deprecated in MacOSX 19.8 and later. Please use -[NSImage drawAtPoint:fromRect:operation:fraction] instead.
There are a ton of other warnings. Before I go through this again, can someone tell me if this is normal (all of it -- above too); or if these are symptoms is a keystroke logger or hardware issues?
I ask because originally, when my computer went in for diagnostics (more than once), Apple stated the hardware was fine (other than Airport Card -- finally). However, if I've done 5-6 total wipes; created new users; do not have sharing set-up; have not played around in Terminal; and am up-to-date with versions -- and various issues KEEP COMING BACK -- I am left wondering if a keystroke logger would be possible here?!? I thought maybe a faulty logic board, but why would diagnostics be okay, then? Not trying to be hyperbole, just desperate.
Please help me rule keystroke logger out or at least, tell me so I know, so I can take appropriate action. If you think it could be the logic board with symptoms above, that would be a great too.
All I want to do is use the computer as intended, but I can't seem to get a real answer, so after nine months -- I am turning to the communities to see if anyone -- anyone at all -- can help. The last thing I can do is have the MBPR come back from the depot and the same thing occur. Any guidance or advice would be so gratefully appreciated.
