Lightroom cannot write to /Volumes/Data after creating dual booted volume

[ericv13334838]

I have configured by MacBook Pro for dual boot, and am moving Lightroom & data to a new volume.

Now, on the new volume, I get the following error:
Lightroom cannot write to the following directories. until this problem is resolved, syncing from lightroom may not work correctly
/Volumes/Data



Well, it is expected Lightroom can't write to /Volumes/Data, as that is the Data volume for Macintosh HD.
The dual booted MacOS uses a volume called alternate which mounts /System/Volumes/Data:
Macintosh HD -> /Volumes/Data
Alternate -> /System/Volumes/Data

I have two questions:

• How can I fix this?
• Why is Lightroom hardwired to volumes instead of directories? (which I did copy over)

Go to Preferences - Lightroom Sync and change the location for synced images by clicking the 'Choose...' button. Right now it is set to Volumes/Data, but Lightroom Classic has no permissions to write to that directory and should not have permissions.

Thanks.

I actually tried that, but it did not work before. As the path on each volume is the same (/Users/eric/Pictures/Lightroom/Cloud), maybe Lightroom did not register it as a change (even though clearly recording the volume somewhere).
So I renamed it twice /Users/eric/Pictures/Lightroom/Cloud -> /Users/eric/Pictures/Lightroom/Temp -> /Users/eric/Pictures/Lightroom/Cloud, and bingo: that worked.

It works for me now.
