'Your graphics processor is incompatible'; OpenCL greyed out (Early 2015 Macbook Pro, 10.15.7)

[toml11924954]

Hi all. When I opened Photoshop earlier today, I was greeted with this box telling me that my graphics processor is incompatible, even though I have been using Photoshop seamlessly this last month or so and never had this pop-up before. Updating to the latest version of Photoshop (23.4.2), restarting my computer, and closing and reopening Photoshop several times did not fix the issue. I am currently running Catalina 10.15.7 but don't really want to update my OS unless there's no other option. Any help or advice would be appreciated.

It is old one which may be outdated for newest versions of Photoshop. In general Adobe is recommending GPU with score 2000 or more PassMark Software - Video Card Benchmarks - GPU Compute Video Cards Your Intel Iris 6100 has score 564.

You can try to update driver as recommended in that warning dialogue, what means you must update OS.

Thanks for getting back. I'm still fairly surprised as I've been using the 2022 versions of Photoshop on this computer without any problems or pop-ups like this until now.

I have a mid-2012 MBP running 10.15.7 with an onboard Intel HD 4000 and my GPU report is the same yours. OpenCL is not important unless you want the Oil Paint Filter. OpenGL is the important part and you can still run Photoshop as before.

Hi, @toml11924954 each incremental release of Photoshop might make small changes in the usage of the CPU, GPU and the  system API used to interact with them. 

Usually, Photoshop supports the current and previous version of the OS.

Unfortunately, display drivers comes with software updates on a Mac, not sure if Intel does update theirs often.
I know that some clone a copy of their current install on an external disk when they upgrade their OS, in order to have a dual boot fallback method.

You are right on the trailing edge of compatibility. My 2015 iMac has Iris Pro 6300 which is still supported, but anything much older will not be. I'd consider updating to Big Sur or Monterey, Catalina is going to be unsupported this fall when the next version of macOS is released.

How did you get that information about Catalina being unsupported this fall when the next version of macOS is released?

https://nextcraftsecurity.co.uk/macos-end-of-life shows past end of support dates which does go to Dec 1st at the latest, still technically fall. While the dates can officially vary, I wouldn't bet past the December 1 given their history.
