There is one thing that I’d like to see fixed, and soon, and that is the problem with the Intel HD Graphics hanging when it sleeps/wakes up.
I had looked at it months ago already, and quickly identified the problematic kext – AppleIntelSKLGraphicsFramebuffer.kext – and yesterday evening I used a good 30 minutes to nop/0x90 out some parts in the binary and the hang is gone.
Not only can I wake it up, but now I can also connect to it with screen-sharing/remote desktop. The latter did not work. Not without the modified bits, so this is good news. This also confirms that I am looking at the right spots.
The crappy part of the good news is that I have to find a good solution, one that works, and I think to have a good idea. Thanks to a not so good night of sleep – I probably kept working on it some time when I tried to sleep, because I woke up with a lightbulb moment. Yeah. Good news. New ideas!
Keep you posted 😉
