I have an install of mojave going... Two actually.
The issue is stability. Though the fresh install is better, when stress testing the machine by running DaVinci Resolve through some challenging footage that stresses the cpus and gpu, it seems to work fine and then eventually (about 40 minutes in to the last test) Resolve stops rendering and while the system isn't frozen it slowly starts locking up and hanging on processes. Sometimes I've seen kernel_task start shooting up in cpu usage (which I've read the OS does when it thinks things are overheating.
I posted my EFI in the thread in the Mojave forum, but I can cross post if it would help.
Thanks
