Rogue Amoeba has released Airfoil 4.5.5, a minor update to its popular remote audio transmission app. The main focus of the new version is the correction of several issues related to Mac OS X 10.7 Lion, one of which is a severe crash. In addition, Airfoil now sports improved compatibility with Google Talk, Muse Controllers, and Radium (although the latter requires an as-yet-unreleased version of the Internet radio player app). ($25 new, free update, 11.3 MB, release notes)
Wake On Demand in Snow Leopard
Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.
While the requirements for this feature are complex, eligible users can toggle this feature in the Energy Saver preference pane. It's labeled Wake on Network Access for computers that can be roused either via Wi-Fi or Ethernet; Wake on Ethernet Network Access or Wake on AirPort Network Access for wired- or wireless-only machines, respectively. Uncheck the box to disable this feature.
