Apple has released a trio of seemingly identical updates for recent Macs, including the Mac mini EFI Firmware Update 1.3, the MacBook Pro EFI Firmware Update 2.2, and the MacBook Air EFI Firmware Update 2.1. The updates improve the stability of Internet-based recovery operations under Max OS X 10.7 Lion, resolve unspecified issues when connecting to Thunderbolt displays, and improve the performance of Thunderbolt Target Disk Mode. As with any firmware update, you should read the installation instructions carefully before installing. To ensure you get an update only if it’s necessary, we recommend relying on Software Update; if an update doesn’t appear for you, it’s not appropriate for your Mac. (Free, 4 MB)
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.
