Apple has released AirPort Base Station Firmware Update 7.7.3, which is recommended for all AirPort Extreme and AirPort Time Capsule base stations with 802.11ac. Related to the recently exposed Heartbleed bug (see “The Normal Person’s Guide to the Heartbleed Vulnerability,” 9 April 2014), the firmware update fixes an OpenSSL vulnerability that was exposed when the Back to My Mac feature was turned on. After updating the firmware, you may need to re-enable Back to My Mac using AirPort Utility and your Mac’s System Preferences. You must update your AirPort base station using AirPort Utility on your Mac or an iOS device with the free AirPort Utility app installed (the download isn’t available via the Apple Support Web page or Software Update).
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.
