The open-source keyboard launcher Quicksilver has been updated to version β69, a maintenance update with a plethora of fixes that also adds support for OS X 10.8 Mountain Lion. The release now enables Quicksilver’s “paste” action and internal shortcuts to work for all keyboard layouts, makes Automator actions universal, and fixes sporadic opening and closing of the Quick Look panel. It also allows the app’s preferences to be localized and adds French localization. (Free, 3.3 MB, release notes)
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.
