With a focus on improving compatibility with the MacBook Pro with Retina Display, Global Delight has released Voila 3.3, addressing a number of bugs specific to Retina display screenshots in the screen capture utility. Also fixed are crashes related to multiple monitor setups and a video corruption problem on the MacBook Air. For those with the MacBook Pro with Retina Display, note that you can set different export formats in Voila’s Export preferences; that way you can easily export more-compact formats when the Retina display screenshots are too large for email or a blog post. ($29.99 new from Global Delight — with a 25% discount for TidBITS members — or the Mac App Store, free update, 13.8 MB, release notes)
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.
