Some problem with using the feature AirPlay mirroring (also known as AirPlay Mirroring) on MacBooks Pro (released in 2013) and new Macs Pro? I ask because he painted a new support article on the Apple website covering just that: frozen images and / or loss of connection on these Macs.
Apparently the problem only occurs in networks configured in 802.11b or 802.11g standards, and is easily solved. Just turn off Bluetooth (Bluetooth System Preferences Disable Bluetooth or via the shortcut in the OS X menu bar) so that AirPlay performance improves considerably.
As well as the proposed workaround to solve a problem in Mail, Apple did not inform if or when it intends to solve everything. But let's believe and hope that OS X 10.9.2 or a future firmware update will correct this (even though it is specific to the 802.11b / g standard on some Macs).
