Apple has issued a System Management Controller (SMC) update for the MacBook Pro with Retina Display, which fixes several sleep and wake issues for users running Mac OS X 10.7.4 Lion. Additionally, like the SMC updates recently issued for MacBook Air models (see “MacBook Air SMC Updates 1.5 and 1.6,” 27 July 2012), this one enables Power Nap support when running 10.8 Mountain Lion.

Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
