Apple has quickly issued MacBook Pro (Retina) Trackpad Update 1.0 for its just-released MacBook Pro with Retina Display to address an issue that affected the trackpad’s responsiveness (see “New MacBook Pro Features Retina Display, Flash Memory,” 11 June 2012). The updater will be installed into the Utilities folder within your Applications folder, and will launch automatically. (Free, 1.26 MB)
Disable Caps Lock
If you find yourself pressing the Caps Lock key accidentally as much as I do, note that you can disable it entirely in Mac OS X. Open the Keyboard & Mouse preference pane, click the Modifier Keys button, and in the dialog that appears, select No Action from the Caps Lock pop-up menu. You could remap it to another modifier instead, but that might make using differently configured Macs more difficult.
