My 2c here, I’m on Mac too, but not yet Catalina, however just learnt from a colleague that the big thing with Catalina is that you have to explicitly set permissions (typically just once for each “issue”).
This was raised during a Slack Screenshare, something that had run for years, but after upgrade, my colleague tried to share but the wrong screen appeared and was unable to share his laptop screen. Had to dig through the Catalina permissions to set it (took 1 minute, he knew where to go) and then could share OK again. I’ll discuss with someone today and let you know, but sounds like you may need to permission the “owner” of the directory perhaps to view the files. I’ll update you later with what I can learn. …/Rob > On 15 Oct 2019, at 6:09 am, Pablo Landherr <[email protected]> wrote: > > Some further clues. > > I now think it's something with the directories that's keeping J out. > Before, I had copied the entire directory from one HD to another without > any improvement.
