Rogue Amoeba has released Airfoil 4.7.5, which restricts searches to your local network to prevent possible issues with Back to My Mac and iCloud. The update also fixes an issue with failing to open a DVD in Airfoil Video Player, prevents a crash if the Transmit button gets pressed exactly as an output disappears, and provides some small improvements for Retina displays (a full Retina display update is yet to come). ($25 new with a 20-percent discount for TidBITS members, free update, 10.6 MB, release notes)
Open Links from Mail in the Background
Tired of switching back and forth between Mail and your Web browser every time you click a link in a TidBITS issue or other email message? Here's an easy workaround. Hold down the Command key when you click links in Mail to open them in your browser without switching away from Mail. That way you can keep reading in Mail and then read all the Web pages you've opened.
