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).
How Loud Are Your Mac's Fans?
When they get hot, Macs turn on various internal fans to keep components cool. The noise can be annoying, but just how loud is it? If you have an iOS device with a built-in microphone, you can download one of many free sound meter apps (search on
decibel in the App Store) and see if you're subjecting your ears to a truly unreasonable noise level.
