Hi, I have a 2012 retina macbook pro, and I'm running MacOS Catalina 10.15.7. It also has NVIDIA Geforce GT 650M 1GB & Intel HD Graphics 4000 1536MB.
I have been using photoshop with no problems at all, but then out of nowhere, I suddenly start getting this error message when I'm trying to do basic tasks such as using the brush tool: "The 3D features require that 'Use Graphics Processor' is enabled in the Performance preferences. Your video card must meet the minimum requirements and you may need to check that your driver is working correctly."
So I go into the performance settings and I can't check 'Use Graphics Processor' because there is this error message:
"Photoshop detected an error in your display driver. Update or reinstall the driver and check Graphic Processor to retry."
My Macbooks up to date, and I've tried suggestions from other topics like this, but nothing seems to work. It's so frustrating because I'm trying to meet a University deadline, and I haven't been able to work on it all day. I would greatly appreciate any suggestions!
Unplug your monitor and relaunch Photoshop - does the error still occur?
Just checking, but your recommending I physically detach my MacBook Pro laptop screen?
You list two graphics cards - I assumed you were connected to an external display.
I haven't any luck following step 7 I'm afraid. Thank you though, it was a good suggestion.
You can try disabling the Intel graphics. Note that the nVidia card is old enough that it may not be supported for graphics acceleration.
