Apple has released a Thunderbolt Firmware update for mid-2012 MacBook Pros to fix Thunderbolt storage and cable compatibility issues. Those problems, however, are still reportedly present in some of Apple’s iMacs.

Following numerous posts on Apple’s Support Communities that highlight concerns about unreliable Thunderbolt performance with some of Apple’s Mac line-up, including complaints from some vendors, the ‘Thunderbolt Firmware Update v.1.1‘ “addresses an issue with MacBook Pro (mid-2012) and some Thunderbolt cables that make prevent bus-powered Thunderbolt devices from functioning properly,” according to Apple’s description.

Before the update, some users suggested wrapping Thunderbolt cables in tin foil to prevent electromagnetic interference; others said that it was an internet connectivity issue. Users were finding that their Thunderbolt storage drives were freezing during important processes such as backing up data.

ZDNet reports that, while MacBook Pro owners have now received a solution to the problem, iMac owners are still experiencing issues. Several posts on Apple’s Support forums say that, when iMac owners plug their Thunderbolt products into their MacBook Air, previously experienced connectivity issues no longer occur.

Perhaps Apple is waiting to release a Thunderbolt-related update for iMacs after the new models of the desktop all-in-one computer are shipped, which is expected to be on Friday.
