Boosting the Mac version of its podcatcher app with AirPlay support, Jamawkinaw Enterprises has released Downcast 1.0.3 with a number of new features and improvements. The update adds a preference to prevent screen dimming while playing videos, hides the cursor during video playback, makes significant improvements in iCloud syncing and stability, ensures the progress indicator is displayed when importing files, and makes several improvements to VoiceOver. It also fixes a bug that caused episodes to be marked for streaming instead of being downloaded and an issue that prevented the played/unplayed status from syncing correctly. ($9.99 new from the Mac App Store, free update, 6.1 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.
