I have just (in last 2-3 days) upgraded 3 of my iMacs from 13.0.5321 to 13.2.5321. My Mac laptop remains at 13.0.5058. After some experimenting, I have discovered that I can connect with the laptop (originating connections from both local computers - laptop to iMac, and iMac to laptop). Everyting works. When I try to log into one of my remote iMacs, I get the initial log-on screen (requiring username and password). The mouse pointer moves at my direction but has no effect on either username or password command boxes. As well, the keyboard has no effect. I noticed that this problem arose immediately after I remotely upgraded the 2 remote iMacs. When all were running v13.0.5058, all was well. After upgrading to 13.2.5321, no joy.
Does this upgrade require a system re-boot? Since the upgrade, I have re-booted the local iMac but not the remote iMacs. I should say that the laptop also has no screen control with the remote iMacs.
I am going to try and send a remote signal to re-boot to see what happens.
After that, other than physically sitting in front of the 2 remote iMacs, I am out of ideas.
Suggestions?
