Using Mac Catalina 10.15 with the latest update of PS 21.0.1 and Lightroom Classic 12.0. When ever I try to import a file from Lightroom via "Edit in Adobe Photoshop 2020..." like I always have done I can not get the file to open in PS. I get one of two things. A: Cannot open file ****.dng due to disk error or B: literally nothing happens. I did not have this issue before the upgrade. Additionally I attempted to uninstall the current version of PS and go back one version and it is giving me the same issue. One thing I did note was that when I opened LR for the first time after the update it had me upgrade the Catalog folder and gave it a new name. Anyone else having this issue or have a work around?

Did you check your disk to see if there are problems. Is the message correct or not correct.
I ran the Mac Disk Check and it didn't show anything wrong. So far all the files open up in Lightroom as well so as far as I can tell it should all be good to go.
At this point I have unistalled both PS and LR and reinstalled but getting the same errors. Not sure what else I can do at this point.
Just figured out the solution. Went to System Preferences Security and Privacy and added Photoshop to have access to my Harddrive and now it is working.
I am having the same problem..Just started out of the clear blue and only on my Mac Book not on the iMac. started after I upgraded PS to the newest update. I went to privacy setting but can't figure out how to add PS.
I had the same problem. This sorted things out for me. Thank you!
Thank you Troutt! I spent over two hours and couldn't fix the disk error problem. I knew it has something to do with the Mac upgrade, but couldn't figure it out. Thanks to your message and share the solution.
