Is anyone having problems with the new update? I try to update mine and it keeps on asking to quit Safari even if its closed. Even tried force quitting it, restarting Mac, and none of those worked. I tried downloading new Flash11 dmg file but still didnt work. It keeps on giving me that "Please quit Safari before install". Even after I hit "retry" it gives the same message. Installation stops around 50%. Anyone aware of this issue and knows how to fix it? Thanks. EDIT: Forgot to mention, running Mac OS X 10.8.3 on 2011 MBP.
