When Apple released MacBook Pro machines these year, it had integrated a revolutionary new method of data communication in those. The machines came with ‘Thunderbolt’ technology, which essentially allows a supported Mac to connect with another device through a high-bandwidth connection. Users initially reported some problems with it, and Apple has shipped out a firmware update to fix those.
Thunderbolt has only recently been implemented by Apple in its computers. So it is no wonder that a number of problems have been found in it. Specifically, users have widely reported that a number of bus-powered Thunderbolt devices didn’t exactly work very well when connected to 2012 MacBook Pro machines.
Apple has now released a firmware update which is intended to resolve these issues. The update is fairly small, sized at a mere 442KB. You can download it from the Software Update section of your Mac. However, you will be able to do so only if your specific Mac machine is supported.
You can check this out by going to ‘About this Mac’ from Apple menu and then hitting the ‘More info’ button. It will reveal the exact make of your Mac machine. If your machine is categorized as ‘Mid 2012’, that means that it qualifies for the update.
The update requires OS X 10.7.4 or later and your machine must be connected to a power source while it is being installed. Installation will also require restarting the machine.
