Rhino Freezing entire Mac suddenly


I have been experiencing a recurring problem since I updated my Macbook pro to OS Catalina 10.15.4.
What happens is that my computer completely freezes- as if it has been shut off, but with the display still on. The forcetouch on the trackpad stops responding, the keyboard light goes off, etc. This happens suddenly, in different files (both light and heavy) and does not seem to have a correlation with any specific commands. I get no slowing down or any indication that it is about to happen.

I have urgent deadlines and no access to another computer thanks to COVID, please help!

I suggest taking your mac to the apple store when it reopens or ask for online assistance from them. This sounds like like a system problem.

Unless there are Kernel Mode Kommandos programming at McNeel, what you are describing would have to be an operating system bug or a hardware problem.

I don’t see any obvious problems in your SystemInfo other than you Mac is getting pretty long in the tooth.
We are seeing a few reports of problems with these older Intel 6000 and 6100 Macs running under powered GPUs.
Your MBP is 5+ years old now so my guess is things are not going to improve going forward.
