Lightroom CC reports wrong available disc space

I'm running Mac OS Mojave and I've run into a problem while saving images from Lightroom CC on to my harddrive. System profiler shows me 281GB of free disk space, but Lightroom CC sees only 28.74GB. This might have to do with the "purgeable" concept Apple has introduced in High Sierra. I have attached a couple of screenshots where you can see the different locations in the system that report the disc space.

I hope someone can tell me if I'm doing something wrong, or that this bug gets resolved in Lightroom CC

Yes, it's to do with purgeable space.

I had this recently too. In my case, it turned out that Time Machine was storing temporary backups on my boot drive because the external drive had died. I googled for a terminal command to clear out those backups and my LR available space went back to matching the OS available space, so I'd start by looking there.

Yep... that seemed to do the trick. I had 5 local backups. Thanks a lot! However, as you see with my post below. I strongly think that Adobe needs to address this, since in Mojave it is not possible anymore to disable local backups. So it will happen again and again.

You can disable time machine still though, right? And if the drive's attached, it doesn't need to do local backups, if I understand it correctly. Mine hasn't recurred since I turned off TM (as I have other backups).

Thanks for the help! I'll look into that. However, I still think that Lightroom needs to be able to get around this since it is now a native feature of OS X.
