Duplicating a fix provided by the recently released Firmware Update 1.6 (see “SMC Firmware Updates for MacBook, MacBook Pro, and MacBook Air,” 31 January 2013), Apple has released MacBook Pro SMC Firmware Update 1.7 to target a range of specific models — both 15- and 17-inch MacBook Pro models released in mid-2010 and early 2011. Like the previous update, this one addresses a “rare issue” that caused laptops with a battery that had accumulated more than 1,000 charge cycles to shut down and possibly fail to boot back up again. As always with firmware updates, we recommend relying on Software Update or the App Store app to ensure you get the firmware update for your MacBook Pro, and being careful not to interrupt the update process.

Untrash the Trash
Feeling trasher's remorse? On Snow Leopard, you can open the Trash (click the Trash icon in the Dock) and "untrash" individual items there. Select one or more trashed items (files and folders) and choose File > Put Back. This returns the items to where they were when you originally put them in the trash. The keyboard shortcut is Command-Delete - the same as the shortcut for trashing an item in the first place, since in deleting something from the trash you are untrashing it.
