We had several clients upgrade (unfortunately) also.
We just needed to have them:
- Go into “system preferences”, and then “security & privacy”
- Go into the “privacy” tab
- Then for “Accessibility”, “Full Disk Access”, and “Screen Recording” on the left hand side they will need to put a checkmark next to “Remote Access”
- Some of the things will say that it won’t take effect until the program is quit, and it will provide a dialog box to quit remote access, do that.
You should now be able to remote control again
There are some pictures that will show you what I’m talking about here (but it’s for teamviewer):
Good Luck!
