Problem solved by installing P/S from Creative Cloud on to the new computer. Many thanks for your help.

You migrated your software from an older, Intel Mac. This DOES NOT WORK. You need to use the CC App to completely uninstall and reinstall all of the Adobe software.

You get those errors because you are running Intel software on your new Apple Silicon Mac in Rosetta mode.

Thank you. I did not migrate from my old iMac. I used a portable hard drive to load data. What you say makes sense. Thank you for your suggestion . I will try it out. I appreciate your answer.

Well, M4 obviously has full AVX2 support, so this message makes no sense.

Is Photoshop running in Rosetta mode? You need to run in silicon-native mode.

Makes no sense? I didn't write it. I have no idea what Rosetta or silicon-native is.

How can I check the GPU compatibility report?

With the Photoshop 23.0 release, you can run the graphics processor compatibility check to ensure your GPU is compatible:

Go to Help > GPU Compatibility and see the report dialog that opens.

Here is my report (MacAir M1)

Additionally, click on the Apple icon, then About This Mac>More Info>General.

Click on System Report at the bottom of the About screen.

In the left column, click on Graphics/Displays; look for Metal Support.

Which camera are you using?
