reinstall Mountain Lion on 13" macbook pro retina

Welcome to the Apple Support Communities

Mountain Lion is preinstalled on your computer. To reinstall, use Internet Recovery because your computer needs a special OS X version that it's not available in the Mac App Store

Are you trying to restore to factory settings? If so, use the Internet Recovery method - hold down the Command, option, and R keys whilst booting. Use Disk Utility to erase the flash drive, formatted as "Mac OS Extended (Journaled)" with a single GUID partition.

Then reinstall the version of OS X that shipped with your computer. Make sure that you have a good Internet connection before attempting - wired Ethernet is best, but if you don't have the Thunderbolt>Ethernet adapter you can use wireless... it will just be slower.

Your computer shipped with a special build that is currently not available from the Mac app store to reinstall OS X. That's why you're getting that error. Apple is aware of the issue & working on an update. You will not be able to reinstall until this update is released. You can call AppleCare...they are aware of the issue & may replace your computer.

ETA? I "upgraded" to 13 as well, and can't see my iPhoto Library at all, among other things I'm missing in ML.

Well, it is two months later now and I just wanted to clean install Mountain Lion on my MacBook Pro Retina 13" (brand new - but Apple Care recommended me to do so..) and surprisingly this issue has still not been solved because I also got to see that message: 'OSX Mountain Lion is not compatible with this computer'..

I got the same problem. Bought my Macbook 13 retina last friday and cannot upgrade to mountain lion.

Your machine should have shipped with Mountain Lion! And I thought that the 'cannot upgrade to 10.8.2' days were long passed. Did your rMBP ship with Lion, or can you simply not upgrade to 10.8.2 (which should be available via Software Update now)?

I've called Apple Care and they learned me to the following in order to complete a clean install from Mountain Lion on a MacBook Pro Retina (otherwise it won't work): http://support.apple.com/kb/PH11273

But, like Clinton said, shouldn't your rMBP come with Moutain Lion on it? And if so, why can't you upgrade to 10.8.2 because I could (with software update) - but my problem was to clean reinstall ML on it from the App Store (that you stil can't do with a rMBP btw).

And a small question off-topic: How long is your (average) shutdown time on your rMBP 13"?

i got OS X 10.8.2 installed if i check the mac. When i try to buy the lion via de app store it says that my macbook isn't compatible. It shuts down really fast.

So you've got the rMBP preinstalled with Mountain Lion and you have 10.8.2 on it now. Why do you want to buy/download Lion in the App Store? Or do you mean Mountain Lion?

If you want Mountain Lion as a backup you do not need to download it from the app store (that is not possible at the moment for users with a rMBP because we have a different version from 10.8.2 than all the other Macs). When you want to do a (clean) reinstall you just follow the steps fromt the link I've posted earlier.

Thank you btw, for your answer about the shutdown time.

No OS X 10.8.2 is preinstalled. I want to install Mountain Lion on it. But keeps saying that it is not compatible.

You want to install Mountain Lion on it, but 10.8.2 IS Mountain Lion, do you know that? So you alreeds have Mountain Lion on your rMBP.

Is that so? But when i watch the video of Mountain Lion you have facebook and twitter options in the message center and all. But i cannot see this options on my rMBP.

I found how to activate those options. I had to login via safari instead of firefox. Thanks for the help guys!
