I installed and removed Pixelmator from my 10.8.2 rMBP. But if I right click on a .jpg it asks if I want to open it with Pixelmator which isn't even on my system! I read to remove com.apple.LaunchServices.plist (I dragged it to my desktop). Rebooted. And Pixelmator is still there! Help! --- [RESOLVED] I still had Pixelmator in my trash and my OS still saw the program as active. I deleted the trash and now my "Open With" associations are correct!
