Impossible to edit LR-classic-files in Photoshop

Hello,

Following the transfer of Photoshop and Lightroom from iMac to a new Mac Studio with M2 Max chip, using Mac OS Sonoma 14.4., I experience the following problem: while in Lightroom choosing edit in photoshop, photoshop opens but the picture file from Lightroom will not open. The following message appears: Could not open file, because the file is locked, or because I do not have the necessary rights (to the file), or the file is used by a different program. I have never experienced this before. How do I solve it? All my pictures are stored on the same external discs as before. The preferences in LR are exactly the same as previously.

Currently I have LR Classic 13.4 and PS 25.9

Did you migrate the apps from the old Mac to the new Mac? Or do a fresh install?

If you migrated, try uninstalling them and reinstalling fresh copies from the Adobe Creative Cloud app.

I did a fresh install, and have also uninstalled and thereafter installed PS first.

Photoshop easily opens any file from my external discs , but PS still do not open the files when asked to do so via Lightroom.

Hi again,

All of a sudden, after closing PS and LR, then restart LR - it works. It is now possible to edit files in PS via LR! Beats me what happened, just happy they communicate normally!

Thanks for your advice.

Select the external disk in the Finder and choose 'Info' (or press Cmd-i). In the info dialog that comes up, look at the way at the bottom for the disk permissions. Do you see a checkbox 'Ignore ownership for this Volume'? Is the box checked? If not, check it (click the lock and enter your Mac password to make that possible).

Hello Johan,

Thanks for advice. I have checked both of my external disks, and this box is already checked in both of them.

Last idea: try resetting the preferences for Photoshop, and if that does not work also for Lightroom.

Hi again Johan,

All of a sudden, after my last comment to you a few minutes ago, I closed PS and LR, then restarted LR - and it works! It is now possible to edit files in PS via LR! Beats me what happened, just happy they communicate normally!

Many thanks for your advice - much appreciated!
