Photoshop 2021 won't open on MacBook Pro running macOS Big Sur

I found a solution that worked for mines

CMD+Option+Shift keys. Photoshop open a dialog asking if you want to delete your Preferences reply YES.

This was the only thing that worked for me. I was one hour into learning affinity which I still might do for a back up. 

Let me know if this helps

Thank you, but after talking to helpdesk it seems my THREE YEAR OLD macbook pro's graphics card isn't supported by the latest PS version! I deleted it and installed previous version and it's fine now. However, it will make me look at PS alternatives that do support my laptop card. 

Hi,

We're sorry about the trouble with Photoshop while trying to launch the app. Please check if Photoshop has the necessary permissions using the steps suggested below:

1. Go to the System Preferences for your Mac, then Security and Privacy, then select the Privacy tab.

2. Then select Accessibility from the list to the left & check if Photoshop is added to the list with a check mark in front of it.

3. If Photoshop is not a part of the list, please add it by unlocking the window first using the lock at the bottom left, then clicking the + icon & navigating to the Applications folder.

4. Also, grant permissions to Photoshop under Full disk access located in the same list as Accessibility.

5. Once done, restart the Mac & check if it helps.

If the issue persists, you can try to reset the preferences of Photoshop using the steps mentioned here: https://adobe.ly/2Qzc0K3

Please backup your settings prior to resetting the preferences. You can check: https://adobe.ly/2vNz6FG

Let us know how it goes!
