This page and scroll down past the list to the blog: 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. ![]() In addition, Steve Schow writes that he has abandoned further development - because there are better solutions available. app for direct download - you do not have to compile anything.Īlso note that if your Mac does not run long enough to allow gfxcardstatus to be added, this is not really practical. 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. 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. 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. This may allow your MBP to run normally, although it will have reduced graphics performance when permforming demanding graphics tasks. It will allow your MBP to run on integrated graphics only, bypassing the discrete GPU which has the issues. Install gfxCardStatus ( ) and set it to "i" (integrated graphics only). The issue they encountered was that sometime the Discrete graphics chip broke, and in other cases, the Discrete graphics chip could not wake quickly enough from a low power state.
