BIG problem. My computer has intermittently shown this problem (in the title). The screen goes blank, fans go very loud, then the computer restarts itself. This happens mostly when using Logic, and more so when EuCon is active. However, it has also happened when simply using the internet... like right now, when I'm searching for a solution!
It's been stress-tested (by the fine folk at CreatePro), and, according to them, the CPU, GPU and logic board have shown no problems at all.
A quick run-down of my specs: Mac Pro 5,1 mid-2010, 64GB RAM, 12-core 2.66GHz; Mac OS 10.12.6.
I have checked out the logs when these problem have occurred, and it looks like WindowServer and libdispatch client are both present in most of these reports.
If anyone can help me with this, that'd be incredible. Am at my wits end, and have work to do, dammit! I've copied excerpts from the reports below. Thank you so much for reading! Nick
