Marcel Bresink has released TinkerTool 4.95, a small update to his under-the-hood customization system utility. The app now offers a setting that enables the debug menu of Disk Utility and the App Store application in Mac OS X 10.7 Lion or later. For 10.8 Mountain Lion users, the release adds settings to control smoothing and to disable the default behavior of asking if you want to save new documents to iCloud in supported apps (such as iWork, TextEdit, and Preview). It also adds a pane to control Resume behavior for individual applications in Mountain Lion. (Free, 3.9 MB, release notes)
Avoid Simple Typos
If, like me, you find yourself typing 2911 in place of 2011 entirely too often, you can have Mac OS X (either Lion or Snow Leopard) fix such typos for you automatically. Just open the Language & Text pane of System Preferences, click the Text button at the top, and then add a text substitution by clicking the + button underneath the list. It won't work everywhere (for that you'll want a utility like Smile's TextExpander), but it should work in applications like Pages and TextEdit, and in Save dialog boxes.
