As far as I can tell, you have to open the Energy Saver System Preference to see which one is active.ĭoes anyone know of a tool that will display (in the menu bar, on the desktop, whatever) my current video card status? Especially good would be a terminal command that would report which one was active. This can end up with a dead battery while on an airplane pretty quickly. The problem is, I often forget which one I am running. It requires only single-User mode to get started, then type a complicated string into NVRAM, then disable System Integrity Protection and run an additional little program (direct-download link provided there) to make the change semi-permanent.There is a big difference in both performance and power consumption between the two video cards in a MacBook Pro. There is a completely different hack developed more recently. But NO external display support any more.

I now have a perfectly-functioning MacBook Pro late 2011 15-in model with Discrete Graphics disabled.

I have made the Arch Linux bootable CD on another Mac, and tried this approach. I used the second from MacRumors as it seemed easier.

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. I have discontinued use of gfxCardStatus to solve the MBP kernel panic problem as the issue is better solved on 2010 models with the nVidia GPU by the following hack: 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). If you can use Single-User mode, you can use the last hack on this list: Be sure to read everything before you do anything. This is my accumulation of links on the subject, it is NOT a single procedure.

Can you Restart into Single-User mode (it will show only a Terminal window with command-line) ?.

Screen updates will be wonky and slow, but ultimately correct.

Can you restart holding the Shift key and get into Safe Mode? In Safe mode, it does a five-minute disk Repair as it starts up, then loads a minimal set of extensions, including NO graphics acceleration.

choose the one you want and tell it to proceed.)

Can you restart holding the Option key, and get the Startup Manager? (it draws an Icon for every potentially-bootable drive it discovers, which can take five minutes or more.

all of these mode are likely to use the Integrated graphics, and not shift to the discrete graphics unless you launch an advanced Application: If you do not edit movies or use an external display, you can use a hobbyist hack to disable the Discrete graphics processor, and keep running on the Integrated Graphics processor.įirst, you would want some additional confidence that this really is the problem. sometimes it would crash with a failure linked to the Discrete graphics processor. The 2010, 2011, and some 2012 15-in Dual graphics models sometimes had an issue where the Discrete Graphics processor would fail, but MacOS would not recognize the failure and would keep using it.
