The new MacBook Pro models powered by Intel's Sandy Bridge CPU may sport the über-fast Thunderbolt I/O interface for incredibly fast connections to external hardware, but those same MacBook Pros are reportedly having problems with a commonly-used wireless interface.
According to a post on AppleInsider, a large and growing number of early 2011 MacBook Pro owners are finding that iTunes Home Sharing isn't working for them. Home Sharing, when working properly, allows a single iTunes library to be shared between Macs, PCs and iOS devices over a wireless network. One Apple support forum user reported that he was initially able to stream from his new MacBook Pro to a second-generation Apple TV without difficulty. Later, the Apple TV began reporting that it was unable to connect to the computer or would display an error message stating that "there are no movies in this library."
Since the MacBook Pros appeared in February, Apple has released iOS 4.3 and two updates to iTunes that added compatibility to iOS 4.3 and Home Sharing. Those software updates do not appear to have resolved the issue, and a related thread in the Apple support forum now has over 220 posts.
Owners of other Macs are reporting similar issues with iTunes Home Sharing, but not to the extent that those using the new, speedy MacBook Pros are. Have you run into this issue or found a workaround? Let us know in the comments.
