Due to all the cautionary words here and elsewhere I put off my Catalina upgrade until a couple of months ago. Mostly seemed to go OK except for one really odd thing on which I’d value the TidBITS Talk team wisdom:
My file structure dates back to pre-OSX days. When OSX came along I saw no reason to change and it’s been working fine until Catalina. I use two top-level folders on my hard disk for personal and business documents. Almost everything important to me is in these two folders. On completing the upgrade they had disappeared. After panic and investigation (won’t bore you with the details) I found they had not actually gone but were relocated into a second instance of my hard disk.
The path to these folders now looks like this: MacHD > System > Volumes > MacHD (again!) > my precious data folders. (The Applications folder appears in both instances of MacHD, and both also have Systems, Library and Users folders but I have not checked to see of the contents are identical.)
After the initial bafflement I got used to this and simply worked around it. Until I found that Backblaze was no longer backing up my precious data folders. Turns out that Backblaze will not back up anything in the System folder, including these folders. Moving them back to the true top level doesn’t seem to work because they get relocated again, I think as a result of system updates (hazy about this because the last time was a couple of months ago and I’ve forgotten the details).
Is this file structure normal for Catalina? If not, any suggestions on how to fix it? I considered a clean install but after re-reading Joe Kissell’s Upgrading to Catalina book I’m dubious it would fix anything.
I can presumably work around this (and get Backblaze working again) by moving my data folders into my Home folder. I haven’t done that partly because I like having my key data at the top level of my hard disk, and partly because I’m troubled that something has gone wrong with my Catalina setup.
I’ll be most grateful for any advice.
