    Hello all,

    I recently did buy a beautiful Apple Macbook Pro A1286, early in 2011 bought 15 inch i7, 8GB RAM and 1000GB.

    However, Windows 10 was installed on it, so I looked at the serial online and purchased snow leopard (Mac OS X 10.6). I did the installation from the CD, however, I can make the choice to start from the CD, but he always hangs at the '' white screen with apple logos.

    Even with Mac OS X 10.6 I created a USB boot disk, but it recognizes the USB sticks and stucks again on the same screen, white screen with apple logo. Even with the recovery of the hard drive I come to the same problem.

    The funny thing is, there is Windows 10 installed from the previous owner and it just works.

    Does anyone have a solution? I am now a making a boot USB with OS X 10.8 (Mountain Lion). I've even done vram reset, but without success.

    Is the software (Snow Leopard) maybe too old for my macbook pro?

    Snow Leopard was introduced in 2009. When new Mac models are first introduced, a lot of times they will require a special version of the OS. Drivers for the new Mac model are then incorporated at some point into the later updates and versions. So there's a good chance that you bought a version of Snow Leopard that predates the 2011 MBP. Mountain Lion should work.

    Be aware (if you're not already) that the model you have has been know to have GPU issues. You can look up "Radeongate Mac". There was a repair program that ended at the end of last year.

    @treekram thanks for the fast response! I dont have any problems that is written on the apple website. The only thing that it doesnt load (only to the white screen with the apple logo). But the weird thing is, that it also doesnt work with the recovery on the hardisk. It starts but then stucks on the same screen. I gonna try it today with the mountain lion and hopes it works.

    I'm not saying that this is the case but it could be possible. It maybe that the person using the computer was using Windows 10 because doing so would avoid using the GPU. While some of the Radeongate issues would be obvious (no video on the computer screen), some may not be apparent for the limited use you've had on the computer thus far. I haven't followed Radeongate closely so maybe I'm mistaken here. Hope everything goes well, though.

    As I understand it, Windows 10 uses only the dGPU on Macs, so the previous owner would have had to figure out some way around that.

    Yeah and now it works. Had 2 times a blue screen, formated also the harddrive (before install) and downloaded gfxcardstatus 2.0.1. Now it doesnt get stuck or a blue sceen! If somebody haves this problem surely try this steps.
