Apple has issued MacBook Pro Retina SMC Update v1.1, which provides a fix for a “rare issue” for slow frame rates while playing graphics-intensive games on the 15-inch model of the MacBook Pro with Retina display. The System Management Controller update also provides bug fixes for Power Nap and wake from sleep, as well as a fix for a fan control issue. While the latter isn’t detailed in the release notes, it most likely addresses the overzealous fan spinning that’s been discussed at great length on Apple’s support forums and noted at Geek.com. After installing, the SMC will be updated to version 2.3f35. (Free, 504 KB)
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.
