"Macintosh HD" is Read Only - MacOS Catalina 10.15

[HaydenMeade]

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.

Problem(s)

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.

What I've tried to do

I have googled the cuss out of this issue. I've tried using Adobe's own script for terminal twice with no success. Solutions to Adobe Lightroom Lightroom user permission issues on launch - that didn't work. I thought maybe it could be a problem with my hard drive, so I ran disk utility and found corruption. I repaired my disk in recovery mode and thought everything was fixed. But still the problem kept happening. I found a youtube video Adobe Lightroom Classic User Permissions Issues-Fix-macOS - YouTube - that didn't work.

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 granted Lightroom Full Disk Access and it didnt work.

Updated to Lightroom V3.0 20191017-0835-b386176 and it worked.

No import error messages now.

(This may be way after the fact, but before updating LR I could not import any photos and had error message on opening.)

Catalina 10.15.1 (19B88)
