I have the latest version of Photoshop Beta 26.5.0 installed. I get a warning whenever I open the software:
Your graphics processor is incompatible
GPU not supported
Metal unavailable
Insufficient VRAM: (0 MB of 1500 MB required)
GPU Detected: $$$/Prefs/Performance/UnknownGPUDeviceName=Unknown GPU (UNKNOWN)
In settings > performance, the whole section for Graphics Processor Settings is greyed out, with the same message for the detected GPU:
GPU Detected: $$$/Prefs/Performance/UnknownGPUDeviceName=Unknown GPU (UNKNOWN)
In my system report, the graphics details are:
Chipset Model: Apple M1 Max
Type: GPU
Bus: Built-In
Total Number of Cores: 32
Vendor: Apple (0x106b)
Metal Support: Metal 3
However, in Photoshop non-Beta 26.3.0, the GPU seems to be detected just fine and shows up in settings > performance as:
Detected Graphics Processor"
Apple M1 Max (APPLE)
In the Beta version, I am also experiencing some crashing, selecting 'select and mask' for example, now crashes every time.
I appreciate that this is a Beta issue though, so this may not be the correct forum for this?
