Apple has released Security Update 2007-004, which fixes a wide variety of obscure security holes and includes new versions of several open source components of Mac OS X, including fetchmail and ftpd. Of particular interest are fixes to Mac OS X's file sharing client software, the elimination of several bugs identified by the Month of Apple Bugs project, and fixes for holes in the Login Window authentication dialog. Academic users should also note that Security Update 2007-004 addresses three different exploits aimed at the Kerberos secure authentication support in Mac OS X. The update is available in four versions, for Mac OS X 10.4 for PowerPC-based Macs (9.3 MB) and for Intel-based Macs (16.1 MB), and for Mac OS X 10.3.9 Client (37.6 MB) and Server (54.1 MB). Or just let Software Update do the job for you.
File Email with a Key in Apple Mail
In Mac OS X 10.4 Tiger or later, you can use the simple and fun MsgFiler Mail plug-in to file Mail messages using keyboard shortcuts.
New in Apple Mail 4 (the 10.6 Snow Leopard version), to assign a keyboard shortcut to any mailbox on the Move To or Copy To submenu, you can also open the Keyboard pane of System Preferences, click Keyboard Shortcuts, and select Application Shortcuts in the list on the left. Click the + button, choose Mail from the Application pop-up menu, type the name of the mailbox in the Menu Title field, click in the Keyboard Shortcut field, and press the keystroke combination you want to use. Then click Add.
