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)
Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
