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)
Thoughtful, detailed coverage of the Mac, iPhone, and iPad, plus the best-selling Take Control ebooks.
