Hi, Photoshop 2020 application, but also earlier versions have a serious error in the openCL settings. The problem concerns the MacBook Pro 16 "from 2019, but I suspect that earlier models. These MacBooks have two graphics cards. In my case, Intel UHD Graphics 630 and AMD Radeon Pro 5500M 8GB. When I mark in the system energy saving settings that the system automatically switches graphics cards, I can not enable openCL in Photoshop settings, despite the fact that when it is started, macos switches the card to the better one, i.e. AMD. However, when I manually set the computer to use only AMD, turn on Photoshop, then in the settings I can turn on openCL. A terribly annoying situation because Photoshop never uses an Intel UHD card. As soon as it turns on, the system switches to a better card. However, somehow, Photoshop doesn't know this and disables openCL. When the AMD card is permanently enabled, openCL works, I just need to re-enable it. Is there an option to fix this to let Photoshop know that it uses a better card and enable openCL acceleration when automatically switching graphics card? Perhaps he should evaluate the card with a delay until the system manages to switch graphics cards. I don't want to use only the AMD card manually, because it uses more energy on the battery, even when I'm not working in Photoshop.

Any suggestions?
Thanks, Marcin
