I've been having an issue when opening Lightroom CC. I have tried several solutions for over 2 hours and I've had no success.
The first noticeable problem is on startup, Lightroom tells me that my hard drive is Read-Only and that I need to either change it's permissions or select a new storage location. So the first solution I tried was to select my external hard drive as the new destination to save files. At first I thought that it worked, the error message went away, I tried to import my photos to get to work and when get to the final import page, Lightroom gives me another error telling me 1 of either 2 things: A) The disk needs X amount of more storage to import, please free up space and try again or B) Error occurred when checking disk space.
When it gave me solution A, I did delete space and it gave me the exact same error message afterward. But that error shouldn't be happening either way. I have over 70gb of free space on my internal drive and 2TB on my External.
After that, I figured that it was more than likely a problem that's specific to the beta version of Catalina and that maybe I just needed to change Lightroom's permissions in my system preferences. So I gave Lightroom complete and total access to my files and folders. I thought for sure I had solved the problem and that the error message would go away. But it didn't. It's still here and I still can't edit or even import my photos.
Please help me, there have been a few other things that I've tried as well, like resetting Lightroom's preferences, but that hasn't worked either. If you have any solutions, I'd love to hear them. I think it might come down to me downgrading from Catalina but I'm hoping to avoid that. Thank you.
I've been able to bypass this issue by mounting OS volume as writable (which is read-only in Catalina) using "mount -uw /" command in Terminal. Works until restart, after that it will become read-only again and you have to remount it again.
