¿do you get the initial "passed my self-test" CHIME?

¿does the power light blink a repeating pattern?

¿do you ever get anything other than total whiteness on the screen?

¿If you hold Alt/Option key at Startup, do you get the System Selector screen after a few minutes?

I get past the chime, the apple logo and countdown circle runs as does the countdown bar, this then goes to white screen about a third of the way down the countdown bar, the mouse pointer shows for a few seconds in the top left corner and will respond, the screen then goes white or sometimes goes black then blue and freezes.

If I put the OSX disc in and startup in C or Alt I get the choice of untitled, recovery or startup disc. I can select any but non have any effect. The startup disc did run for some time, then stopped and the screen froze in this format.

A 15-in with dual graphics from 2010 or 2011 may have suffered a Discrete GPU failure. If you do NOT intend to use an external display, you can try these solutions:

Install gfxCardStatus (https://gfx.io) and set it to "i" (integrated graphics only). It will allow your MBP to run on integrated graphics only, bypassing the discrete GPU which has the issues. This may allow your MBP to run normally, although it will have reduced graphics performance when permforming demanding graphics tasks. The alternative is replacing the logic board, which is not cost effective on a machine that old, unless gfx does not resolve the issue and you really want to keep this MBP.

There is an acknowledged bug in the current version of Cody Kreiger's Open-Source gfxcardstatus, and the developer has confessed he does not have time to fix it right now.

There is a fork off the main build by steveschow available that seems to fix that problem for current versions of MacOS such as ElCapitan and Sierra. He provides a finished .app for direct download -- you do not have to compile anything.


Also note that if your Mac does not run long enough to allow gfxcardstatus to be added, this is not really practical.

In addition, Steve Schow writes that he has abandoned further development -- because there are better solutions available [for both the 2010 model and 2011 models]. In particular, the use of ArchLinux bootable CD to gain access to and re-write the EFI on the drive, and permanently disable the discrete graphics chip. This page and scroll down past the list to the blog:


there are two similar procedure listed. I used the second from MacRumors as it seemed easier. I have made the Arch Linux bootable CD on another Mac, and tried this approach. I now have a perfectly-functioning MacBook Pro late 2011 15-in model with Discrete Graphics disabled. Runs just fine.
