Should you upgrade to OS X Lion??? Meh…. it’s presented more problems than previous upgrades.
Maybe I should have waited until 10.7.1, so this is my punishment for being bleeding edge.
Another issue I saw was the continual nag when I opened some apps (Billings and Cyberduck) that “This program was downloaded from the Internet… blah blah blah” This normally happens once for a program then goes away after you say “OK”, but this was happening everytime I opened those two programs.
The solution.
sudo xattr -d com.apple.quarantine /Applications/Billings.app
This shut the bugger up.
