As to clarify/verify, can you post in a reply a screenshot of that.

Please post a screenshot of the message you get. There is no 'full disk warning' in MacOS. You can be asked to give Lightroom full disk access, but that would indeed be strange if you already did that. So maybe it's another warning about read & write permissions? There is a known issue where the destination of synced images is reset to the Users folder, which is off limits to Lightroom, even if it does have full disk access.

You may need to repair permissions of some folders. See at the bottom of the 'Learn More' linked page (https://helpx.adobe.com/lightroom-classic/help/allow-permissions.html)

I've run across this.

There is a note on the "learn more" page that "If you have Time Machine mounted on your system, the dialog may appear. It is advised to ignore it by selecting Don't show again." I believe "mounted on your system" probably refers to being in the process of a current backup; it could even refer to the filesystem doing its own snapshot work in the background. I'm not entirely sure.

But, basically, if you have already checked that Lightroom has the disk access it needs; you are not actually getting any problems other than this error message; and you use Time Machine... I'd recommend just saying "Don't show again." I have done this and not run into any issues.

[JohanElzenga]

'Mounted' means the Time Machine disk is connected and shown. Maybe this message might occur if you use Time Machine but did not choose to encrypt the backup.

[umlautnord]

Quite possibly! I do have a networked (encrypted) Time Machine setup off an old Airport Time Capsule and the volume never actually mounts visibly, though. If I jump into the CLI or Disk Utility, it's mounted when there's activity—just not actually visible in Finder. I'm guessing when TIme Machine is running even off a disk that's visible/attached, there's an additional volume of a disk image that mounts in the background similarly.

I'm not sure what exactly Lightroom is looking at that makes it want to throw that error, and if there's some locked snapshot state involved with the backup when it's in process. APFS + the changes to Time Machine have gotten a little beyond me in the exact mechanics over the past few years. That's all in the weeds.

I've never had issues with ignoring this error after just double-checking that System Settings has it set for whatever disk access it needs. But! Agreed it makes sense to be sure the Adobe folders have the correct permissions, per what you point to on that page. 🙂
