A day after unveiling its updated slate of MacBook Pros, Apple released MacBook Pro (Mid 2012) Software Update 1.0 for all the new models — covering the 15.4-inch Retina Display version as well as both 13- and 15-inch sizes of the non-Retina models (see “New MacBook Pro Features Retina Display, Flash Memory,” 11 June 2012). Apple states that the update improves graphics stability, external display support, and USB 3.0 device support. (Free, 1.06 GB)
Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
