Hang on mavericks upgrade

Question

tried to upgrade to mavericks last night.  I had a 70-80 minute hang on the 'time remaining= less than a minute' screen.  when I shut it down and rebooted, it started with the new install screen, I'd get to the screen where it clearly wasn't recognising me (wanted me to replace or change my name) and would recycle back to the nations screen again.  before I got to the screen hang, it had not accepted my admin password> I had proceeded with a blank password field.
I recovered the Mac successfully from the time machine backup I ran the night before, but I'm wondering if I missed something?  another possible variable is that I do have Parallels 9 on the Mac with Windows 7 installed (need Windows for school last year).
Has anyone had this issue?

Answer 1

As mentioned by others, sometimes while sharing my screen on my MBP running Mavericks, I'm suddenly logged out -- not logged out of Skype, logged out of OSX entirely. In other words, when I log back in, the only applications running are those set to "Open at Login"... so it's a true logout, you know, like a full reboot without the wait.
But (again, as others are experiencing) sometimes instead of just logging me out, it locks up the whole screen except for the mouse... and audio, oddly enough -- I can still talk to the other call participant(s) until they hang up -- but I can't do anything else until I hold the power button for 5 seconds to completely kill OSX.
For what it's worth, the latter behavior also occasionally occurs in GoToMeeting, which makes me wonder whether some portion of the OSX API you're both using suddenly became disastrously buggy in Mavericks; I know you guys don't like talking to Apple any more than you absolutely have to, but in this one instance it might be more efficient to just ask them, since you know what your code is really doing, whereas we just know how your code is inconveniencing us. Just a thought...
