Is there any hardware issues that could cause a black screen after sleep?
Hi hive mind,
I have a Mac Pro 4,1 -> 5,1, Dual X5690, Gop Enabled on motherboard, RX580 unflashed, Martin Lo's OpenCore 0.9.2, Monterey 12.6.8, 256GB RAM. The machine was working fine before, including normal sleep in both MacOS and Windows 10, until a few days ago.
Since two days ago, the Mac Pro is showing a black screen after sleep. It went into sleep normal, as I can see the lights were out and fan stopped. It seems to resume normal as I can see the light back on and the fan started spinning. But there was nothing on the screen. It is black but not lack of signal, otherwise the monitor would indicate no signal.
The two changes that might be related were below. But these two may not be related to the problem.
1. I upgraded Monterey from 12.6.7 to 12.6.8
2. I started playing games in Windows 10.
I have done the following tests but none have improved the situation:
1. Change RAM to 4 sticks of 2GB each so 8GB total;
2. Try to sleep in Windows 10 but same issues;
3. I have another Mac Pro with 96 RAM and very similar specs. It was also upgraded to Monterey 12.6.8 recently, it is sleeping fine, but at resume, the monitor did have a few seconds of artefacts before resuming normal;
4. I moved the RX580 from Slot 1 to Slot 2;
5. I took out all other PCIe cards;
6. I used High Sierra without OpenCore;
7. I checked the BootROM, looks about the same as when I flashed Enabled Gop 1.3 three months ago;
8. I used a GT 710 but it refused to go to sleep, maybe due to a lack of driver under MacOS. In Windows 10 it had the same sleep problem.
It seems like a hardware problem, any ideas what else to check? Is there any log on MacOS and/or Windows that I can check for errors?
