Welcome to AMD OS X

Why not register now to gain full access.

Help with AMD OS X after installation.

Say, is anyone having random shutdowns, even when not doing something intensive, when running the 3900x on the ASRock x570m, at 10.14.6 18G87. (I still haven't managed to install the Security Update. Every time I try, I get stuck at Randomseed.) Photoshop 2019 used to work with the terminal commands, but not any more, so it's all Affinity now.

Many thanks in advance!!

Below is the problem report generated by Mac OS after rebooting from the random shutdown, which is occurring more and more often. I haven't changed fan cooler settings, yet can't monitor the CPU temp of course, so a bit lost:
