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)
Beware Country-Specific iTunes Stores
If you buy an iPhone, iPod touch, or iPad, and you happen to be a user of the iTunes Store in more than one country, take note which country's store you're viewing in iTunes when you plug in the device for the first time. This will be the country the device will register with, and you will be forever barred from purchasing or even updating free apps from anywhere else. The only way out is to delete everything on the device and do a full restore.
