Lion OS X 10.7.3 combo update bugs
After installing 10.7.3 combo update, I found out some bugs:
The major one is the login screen freezing. Occasionally, when I quit from sleep mode to the login screen. The screen freezes, no respond to either keyboard or trackpad. Then it goes back to sleep mode again. This wasn't happening when I was using the previous version 10.7.2.
Another one is the dashboard calculator. Every time I press once to a number button, it shows up two digits.
I don't use time machine. Will there be any methods that can revert my OS to 10.7.2?
MacBook Air, Mac OS X (10.7)
