Hi @kmachacek , There is an instability on that version of the operating system that makes OpenCL unreliable. As a result, we just released a patch, 22.4.1, that disables OCL features on that version of the Mac OS in Photoshop.
The issue was fixed by Apple, but only offer it in 11.3, so they are recommending customers upgrade to 11.3 for that functionality.
Your shortest solution is to install 22.4.1 and continue on 10.15.7 but without OpenCL accelerated functionality. Your best solution is to upgrade to 11.3.
