My Macbook Pro Retina can't turn discrete graphics on.

I bought Macbook Pro Retina few days ago. Everything was fine, but yesterday my macbook couldn't switch to discrete 650M. And it can't do it now. I tried everything - Formatting SSD and installing everything again, switching between intel hd 4000 and 650M in system settings. In system report 650M is working, but when i play games i see low frame rates and i can't hear fans. One day ago this wasn't like that. There was high frame rate and i heard fans. Any idea what I can do with that?

My Macbook Pro Retina cannot be turned on. Although the welcoming chime is heard.

I have a macbook pro retina 13. I tried to turn it on but only the welcoming chime is heard. Even the apple logo illuminates. The macbook also can be charged. Just that the screen is black.

Macbook pro retina doesn't turn on for a day or two

Macbook Pro Retina 13-inch Late 2012
2.5GHz Intel Core i5
OS X Yosemite (10.10.2)
So this is a weird one... I recently purchased a used Macbook Pro Retina and the previous owner had upgraded the hard drive for a bigger size. My macbook worked great for a few days but then one night I closed it and the next day when I opened it, it would not turn on. I tried rebooting the battery (SHIFT+CONTROL+OPTION and POWER) then hitting power but NOTHING. At one point, I heard a clicking sound when I would leave the power button down. Then... two days later I push the power button just because and BAM! The screen comes on. (I didn't hear the start up sound, and it wasn't like it restarted.) It was as if the screen brightness was all the way down but then came back. (I kept trying to adjust that too before it turned on).
I don't understand!!! Two days later, same thing happened. Then again, it turned back on a day later.
The only thing I noticed that was weird was when I connected it to my tv with HDMI cable. The laptop screen would freeze and get distorted and I would have to force a restart (the black screen with the apple would appear and the loading bar as if I would updating the software).
I'm soooo confused and I don't want this to keep happening. I would appreciate any type of help or advice!!

Macbook Pro retina will not turn on

I bought a 2012 Macbook Pro Retina 13" off Craigslist today. It will not turn on. I tried resetting the SMC and disconnecting the battery and reconnecting it. It will still not turn on, the battery has been charging for 2 hours already and it's still amber on the magsafe. It still has warranty coverage until 2014 so my next stop is the apple store. I thought I could fix it myself but it is pretty tough to narrow down the cause.

I tried those already, did not work.
I did how ever remove the command key and wiped it down and it turns on perfectly!
but now the keyboard keys seem to be out of place or something. For example it makes a "ping" sound when i hit some of them, when i hit function or control it puts the letter Z.
Any input would be great!

I use macbook pro retina can I change ram&harddisk?

I use macbook pro retina my ram is 8GB, but I want to change to 16GB also the harddisk is 256GB I want to change to 1TB could it be possible to change?

The RAM isn't upgradable at all, and the internal drive isn't intended to be upgraded by non-professionals.

New MacBook Pro Retina can't find new Time Capsule.

I have a new MacBook Pro Retina, for which I am trying to set up a new Time Capsule. The Time Capsule is attached by Ethernet cable to my modem, and I have opened Airport Utility. The Time Capsule is continuously blinking amber, and Airport Utility says "No configured Airport base stations have been found." Has anyone else had this problem?

Thank you for your prompt reply. Yes, I am running OS 10.8.2.
MacBook Pro Retinas don't have an Ethernet port - should I use a USB one?

Macbook Pro Retina 15'/Sudden drop in graphics perfomance

Hi, I purchased the base model of the Macbook Pro Retina 15' display 2 weeks ago and recently installed Windows 7 via bootcamp just so I could play a couple of games which were not supported on OS X. Everything was going well until 3 days ago when I turned my mac on, logged into windows, booted up Bordelands 2 and noticed a massive drop in frame rates causing the game to be very laggy. At first I thought it was a problem with the game but then I had the same problem with Skyrim. I then reinstalled Windows 7 and the problem persisted. So I did a CineBench test on OS X Mountain Lion and got 14.7 fps on the OpenGL test which is more than half of what other people get with the same model Macbook Pro. So now I'm stuck on how to fix this, I'm not sure whether this is a software or a hardware problem and if there might be a quick fix that I can do or if I have to take it to an apple store to have it replaced. I would appreciate any help, thanks.

Thanks for this... you just made my day with this one line. Tried to figure out for days what went wrong with skyrim or the macbook pro, but a simple SMC reset helped.
For the record - since I had to google this SMC reset myself too - here is how I done it on the retina MBP:
1. Shutdown the laptop.
2. Make sure that the MagSafe power adapter connected.
3. Press (left) SHIFT+CONTROL+OPTION+POWER buttons once (at the same time) ...no need to hold them.
4. Press POWER button to turn your MBP on again.
Simple as that and worked like a charm for me.
Big up for Ardalaan.

Will the new macbook pro retina's have a dedicated graphics card?

I know that Intel released their new Haswell processors that are energy efficient but I want that graphics power of dedicated graphics. It wouldn't be cool if the Macbook Pro Retina basically gets a downgrade in graphics. I am however all for duel graphics like the current models have.

Nobody can answer this question, unfortunately.

MacBook Pro Retina 13 with Intel Iris graphics breaks Premiere Pro CC hardware output

Hi all,
I just recently got a MacBook Pro 13 Retina, to use for basic editing as a secondary system to my iMac. The MacBook Pro sports a Intel Iris integrated graphics system. When I use GPU acceleration (Open CL), my Blackmagic or AJA Thunderbolt I/O outputs solid green. When I switch to software only, video plays back fine.
I'm running Premiere Pro CC 2014 on Mac OS 10.9.4. I've read that Adobe is now optimized for Intel Iris graphics using Open CL, but why is mine not working when using external video IO?
Anyone run into this?

Does switching off Wifi make a difference?
In UK and USA (and quite a few other places) you have 14 days from purchase to get a refund or replacement - no questions asked. If there is nothing running then this does sound to be depleting rather fast. My late 2013 13" MBP retina gives me about 10 hours using Pages (several documents open) and e-mail only.
Get a replacement and see if you get the same problem.

My MacBook Pro Retina won't turn on! Yesterday I installed the new updates.

So it's fully charged. I used it without any problems last night, then shut it down. This morning when I tried to turn it on, it won't. I have Lion installed and am up to date with all of the software updates. There is a green light in the AC adapter. What should I do??

I know this post is from back in September of last year, but I wanted to comment for posterity to say what worked for me with my July 2012 retina MBP refusing to turn on. From the link preludio posted above: http://support.apple.com/kb/HT3964?viewlocale=en_US&locale=en_US
Use the "Resetting the SMC on portables with a battery you should not remove on your own" method (ie., for all Macbook Pros early-2009 and later). Worked perfectly for me:
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

I bought a macbook pro a month ago and didnt know there was a better/newer model (macbook pro retina) - can I upgrade/take back my macbook and get the new one?

When they told me about it I just thought it had a better display and decided it didn't bother me if the resolution was better, not knowing that it was thinner, has a HDMI connection, etc.
I bought my macbook pro 13 inch exactly a month ago tomorrow. If I go back and tell them this will I be able to upgrade my laptop? I paid more than $1300 or something for this one, I'd be willing to pay up to the price of the retina model, do you think I'd be able to do this?

If your non retina MBP has a dvd slot and a large capacity conventional hard drive, you might find the retina model would have been less convenient with lower capacity SSD and no DVD.
On the other hand, the MacBook Pro with Retina display has got a much faster drive and you can get an external DVD drive (not everybody needs a DVD drive)
Absolutely, like I say personal Choice. I believe from remarks in here that the SSD boots up on Mavericks in something like 10 seconds whereas mine takes even longer to boot than in Mountain Lion. But then we are advised to use sleep over boot as much as possible. My problem is I have 300GB of stuff and getting bigger, and when I bought mine the biggest SSD was 250 I think. For me the choice of replaceable RAM vs soldered-in RAM was a clincher.

Macbook Pro Retina: can anyone help me with running 2 extended desktop DVIs?

I know I need 2 thunderbolt to DVI adapters for this. In the UK these are £25 each, but the MiniDisplayPort to DVI adapters which look the same are very much cheaper .....
http://www.amazon.com/DisplayPort-Female-Adapter-Macbook-Laptop/dp/B003BHHIA4/re f=sr_1_1?s=electronics&ie=UTF8&qid=1359830910&sr=1-1&keywords=minidisplayport+to +DVI
They look the same as thunderbolt to DVIs but is there a difference? Anybody know if the thunderbolt to DVI is an ACTIVE adapter, which means the cheaper versions won't work?
Secondly, I've read scary stuff here from people who think their thunderbolt to DVI fried their monitors. Is there any evidence which supports this?
Does anyone out there use two extended desktop DVIs on a daily basis with a Pro Retina? Any tips or things I should know?

I suggest you buy the Apple TB/MDP to DVI adapters as I have tried another brand and it dod not work. That was on a late 15" 2011 model, YMMV.
Second I have never heard of a Apple TB/MDP to DVI adapter ever frying a monitor of any make or model.
Please post references to this claim.
May be possible with a poorly desinged adapter with some of the TB power output being cross linked to one of the DVI pins/connectors. But still doubtful.

Finder extremely slow on a macbook pro, you can not turn off, and the color wheel appears to move any file

I have a MacBook Pro 2GHz i7 early 2011, 16GB RAM, a 128GB SSD and a 500GB standard. The OS is mountain lion and a month ago my finder is very slow, when moving a file appears the color wheel, also when you send a file to the trash. When you turn it on, the finder takes a long time to be active, the other apps work perfectly. When you turn it off stays white background with the spinning wheel, but never fails to go off. Heat much m'as than before and make lots of noise sinks. Sometimes also starts with the date changed to 2008, not always.
I tried to repair disk permissions, reset pvram even I formatted from a usb and the problem continues.
Please help.

First, back up all data immediately, as your boot drive might be failing.
A common cause of a slow user interface is a large set of image or video files on the Desktop with preview icons. If you have more than a dozen or so such files, move them to another folder.
Another possible cause is iCloud activity, especially Photo Stream synchronization. If applicable, uncheck all boxes in the iCloud preference pane and see whether there's an improvement.
Otherwise take the steps below when you notice the slowdown.
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.
Select the 50 or so most recent entries in the log. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message. 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.

Macbook Pro Retina keeps shutting down during graphics intensive work

Today my macbook began shutting down while working with Aperture, Photoshop and while playing Borderlands 2. This hasn't happened at all until today.
Looking through some suggestions here I have:
Run 2 hardware tests with no negative results. Changed the screen resolution. Turned off Automatic Graphics switching.
However it keeps crashing - actually crashed 3 times while attempting to start it up last time. I've reset teh resolution and graphics switching - hoping someone out there may have an idea??? And I'm not using Google Chrome.

Thanks for any help you're able to give me.

I'll give it a go Ogelthorpe. Ran the more intense hour long hardware test last night and then left it shut down overnight. No results again for the test, but this morning I've run it through a few minutes of borderlands 2 with no shut down. Strange. Am fully expecting it to start playing up again though.

Macbook pro retina does not turn on-

was fine when I closed it and left it to charge overnight
This happened before and I took it to a Genius at the Apple store who took it in the back and brought it back on. Didn't tell me what he did but now I'm travelling and can't go to the store. Does anyone know how to magically make it come back to life?

Look at this Apple support article:

Ciao.

My Macbook Pro Retina can't turn discrete graphics on.
