Every time I open my macbook I get the message ( You computer restarted because of a problem )
panic(cpu 0 caller 0xffffff801d491b2c): Sleep transition timed out after 180 seconds while notifying clients about upcoming system capability changes. Suspected bundle: com.apple.iokit.IOGraphicsFamily. Thread 0x74.
I have tried a fresh install with the same problem. Any ideas?
MacBook Pro 16", macOS 10.15
Had the same problem
Status here
My GPU Panic sleep problem is still solved. I have since installed my video-rendering tools, my developer tools, all my other stuff.
My energy saving stuff is back to normal.
Having it gooing to sleep on power, on batteries
Running 10.15.4
Solution for me was
My brand new macbook pro 16 (Shipped 2. april 2020) also restarted (crashed) over nigth - actually it crashed (Kernel Panic GPU) everytime it went to sleep mode. I had nothing installed except default OSX with updates.
Solution details
I don't know if step 1-3 is necessary, but I think so.
So a macbook pro 16 that I almost returned, is now working perfectly - and I'm very happy:-)
All I had to do was disable "PowerNap" to Prevent computer from sleeping automatically when the display is off. (Problems disappeared).
OK, graphics crash on wake from sleep, we get it.
It's the same solution. As a work-around, Turn off Power Nap. and wait for the software update that fixes the underlying issue.
