I just tried to upgrade again, and it is right now (while I am wrting this) in the "Running package scripts..." phase.
"Install time remaining: About a minute" The blue indicator is almost at the end, but it has not advanced in the last 30+ minutes.
Should I keep waiting? I clicked "option-command-esc", but it does not show the "Installer" as "not responding."
On 12/12 I sent you a private message explaning my situation with screenshots of all the error messages. But now, the problem is that is frozen at that phase.
