Rogue Amoeba has released Intermission 1.0.3, adding full support for OS X 10.9 Mavericks to the audio utility that enables you to pause and rewind up to 3 hours of live audio on your Mac. (If you’re not familiar with it, check out why Josh Centers is a fan in “FunBITS: Intermission Lets You Browse Your Mac’s Audio History,” 11 October 2013.) The update also resolves an issue where Bluetooth audio devices could cause static, improves compatibility with the Soundflower audio extension, and makes several unspecified small fixes.

Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
