Apple pulls problematic Thunderbolt Software Update 1.2

updated 09:52 am EDT, Thu June 14, 2012

Patch caused serious boot issues

Apple has pulled Thunderbolt Software Update 1.2 from its list of available downloads, MacNN has discovered. Although the update was only meant to add support for the Thunderbolt-to-Gigabit Ethernet adapter, some users have complained that it caused serious boot issues such as kernel panics or freezing at the gray boot screen. The only solution appears to have been reinstalling OS X Lion, a time-consuming process.

It's a rare occurrence for Apple to pull an update outright. The company is more likely to offer up a quick reissue, or a later follow-up with a new version number. The Thunderbolt patch's withdrawal may suggest that the problem was too fundamental to fix in a hurry, and/or affecting a number of people.

    The only solution is not

    the only solution.
    The much quicker solution is to install the 10.7.4 combo update. Less than half an hour with a modern network connection. Don't forget to install all available updates after returning to a bootable state. The remaining updates appear to be fine.

    How do you install the combo update on a Mac that won't boot? That's what happened to mine...

    Less than half an hour with a modern network connection.

    Assumes you have a 'modern' network connection, and nothing as slow as DSL or below. Then again, re-installing requires a really modern network connection or 400 hours waiting for a download to finish. Gotta love 'internet restore'!

    Of course, wouldn't it be great if Apple would bother to test these updates before releasing them. We're not talking about one or two anecdotal reports of issues. They are widespread. This happens way too often with apple.

    And the sad part is, they'll re-release it with the same version number and some users won't even know there's a fix out!
