Thunderbolt Software Update 1.2 Causing Boot Failures for Some Users

    Among the many software updates Apple has been pushing out associated with yesterday's keynote announcements, Thunderbolt Software Update 1.2 is a relatively minor 537 KB download offered to provide support for the company's new Thunderbolt to Gigabit Ethernet Adapter. The adapter is intended for use with Thunderbolt-equipped MacBook Air models and the new Retina MacBook Pro, which do not come with an Ethernet port built in due to their thin designs.


    But as noted by TidBITS, the update seems to be causing major problems for a number of users, with some users' machines being rendered unable to boot.
    The report notes that the issues can be fixed by reinstalling OS X Lion, although that is certainly not a desirable step for most users to have to take. Consequently, it seems advisable for users to avoid installing this update until the cause of the issues can be identified and Apple can introduce a revised version of the software.

    Late 2011 MBP is OK. I had already downloaded it when I saw this article and I was praying on the reboot lol.

    bring back plug and pray ;) :D

    I think I'll pass updating my 2011 MBA at the moment.

    No issues here. OS X Lion 10.7.4 on Early 2011 13" MBP.

    Lose a port, gain a crash. Seems like a fair swap to me.

    Had a kernel panic sometime last night/ this morning on my Mid 2011 iMac.

    I think I'll avoid this update for now. I'm glad this was spotted before I heard about the update.

    Fine for me on both early 2011 MBP and 2011 Mac mini.

    I'm still using my 2006 White MacBook. Doesn't even support OS X Lion, which I think is actually a feature. :D

    No problems on my mid-2011 iMac.

    Given the sporadic reports I suspect we'll find it's a conflict with some other software that only some people have. I remember there was some bug a few years back that erased external hard drives, but it only happened with people who had a specific Logitech mouse driver on their Mac.

    Makes it really hard to nail down the problem.

    No problems here. Early 2011 MBP17 w/Intel 600GB 320 SSD.
  19. macrumors 65832


    Early 2011 17" MB Pro. No issues. 10.7.4.
  20. macrumors 6502a


    agree, ill sit this one out aswell.

    Hit me...

    I'm one of the unlucky ones I suppose. I've posted this in a few other places, but yeah, yesterday afternoon shortly after it was released, it popped up as an available update. I was going to be away from my computer (MacBookPro8,2, 2.2GHz quad core 8GB), so I figured I'd run the two updates (this one and iPhoto) while I was gone.

    I came back to a single dialog box that said that the update couldn't be applied. I rebooted the machine (hitting OK simply removed the dialog box but didn't reboot on its own for at least 5 minutes) and got the "driver not found" kernel panic on the next (and 3 other) attempt to boot.

    The only thing I found that worked was re-installing Lion (hold the option key on boot to select the recovery drive.)

    For the record, I had an external monitor hooked up to the Thunderbolt port while running the update - if that's applicable.

    Re-Install Lion

    I downloaded this update last night. My 2011 MacBook Pro 17" running Lion would not reboot and would not install update. Had to shut down and re-install LION. All is fine now. But I won't be trying to download this Thunderbolt up-date again.

    Happened to me last night. Macs don't crash though, its a feature. j/k :p

    But yeah I will avoid this update for awhile, I forget to wait sometimes and just update anyway. I lost my kernel panic virginity YAY!

    Early 2011 MBP here.
  24. macrumors 68030

    Wow, I just ran software update and saw this.

    Thanks for the heads up!
