Apple has released iMovie ’11 9.0.9, a small update for the video editing app that is nearing its third birthday (the iLife ’11 suite was originally released on 20 October 2010). This update squashes a bug that prevented iMovie from recognizing video cameras connected to your Mac and improves compatibility with projects that are imported from iMovie for iOS. Finally, it also includes unspecified stability improvements. ($14.99 new from the Mac App Store, free update through Software Update or the App Store app, 1.08 GB)
Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
