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)
Disable Caps Lock
If you find yourself pressing the Caps Lock key accidentally as much as I do, note that you can disable it entirely in Mac OS X. Open the Keyboard & Mouse preference pane, click the Modifier Keys button, and in the dialog that appears, select No Action from the Caps Lock pop-up menu. You could remap it to another modifier instead, but that might make using differently configured Macs more difficult.
