In addition to adding compatibility with OS X 10.8 Mountain Lion, Apple has updated Aperture to version 3.3.2 with a smattering of improvements. The professional photo organizer now enables you to sort projects and albums in the Library Inspector by date (in addition to name and kind), and adds the capability for Auto White Balance to correct color using Skin Tone mode (even when Faces is disabled). The update also fixes an issue that affected performance when entering or exiting Full Screen mode. ($79.99 new in the Mac App Store, free update, 530 MB)
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.
