Noodlesoft has released version 3.0.9 of its file cleanup utility Hazel, which updates some icons and fixes some issues when viewing the app with the new MacBook Pro with Retina Display, as well as adding a Developer ID that allows the app to be installed without difficulty when using OS X 10.8 Mountain Lion’s Gatekeeper security feature. Hazel 3.0.9 also displays more-accurate error reporting in its preview, prevents a whole pattern getting deleted when you delete a custom token, and fixes an issue with the incomplete downloads setting that was causing prediction errors. ($25 new, free update from version 3.x, $10 upgrade from previous version, 5.2 MB, release notes)
Sleep (and Lock) Your Screen
When you are walking away from your computer, it's fairly common practice to start your screen saver and lock your screen. But did you know that there is a built-in keyboard shortcut in Mac OS X to sleep the screen?
Press Control-Shift-Eject and your monitor sleeps without engaging the screen saver.
