The latest version of the open-source troubleshooting tool AppleJack offers a handful of new features and bug fixes, most notably compatibility with Mac OS X 10.6 Snow Leopard. AppleJack is unique in that you can use it to identify and fix problems on your disk even if you don't have a separate startup disk or your Mac can't boot all the way to the Finder. It can repair disks, repair permissions, clean up cache files, validate preference files, and remove swap files. Along with Snow Leopard compatibility, AppleJack 1.6 simplifies the startup process in both Leopard and Snow Leopard, enhances the SMART status verification process, and adds blessing capabilities for system folders on attached volumes. The update also fixes an unspecified bug that affected user account lists. (Free, 372 KB)
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
