Hey, I'm getting the above message when I select "Easy Install" or "Updates."
The computer is a 2013 iMac.
So I tried "Easy Install" and "Updates" on my 2018 MacBook. No problem.
I get the feeling my 2013 iMac slowing hard drive is the source for the issue. By the time it crunches through my many resources the internet has timed out.
Anything I can do?
