Apple has had almost as many dud updates in the last year as reliable ones. They really have broken faith with their users. It's a sad reflection on what success can do to even the best companies.

Confirmed: only ThunderBolt 1.2 causes the kernel panics. (The other updates appear to work fine)

For those who'd prefer NOT to reinstall Lion, you CAN simply re-apply the 10.7.4 Combo Updater, and you'll be good to go.
A couple ways to do this:

If you have another Mac (MUST also be running Lion), you should be able to boot your kernel-panic Mac into (T) Target more, attach it via Firewire to your good Mac, and run the Combo Updater on the Firewire-attached drive (I did not test this).

If you don't have another Mac running Lion, but can download the Combo Updater to a USB stick (or you may already have this on your HD), you can (off the top of my head, check syntax):

Reboot with Cmd-R (Select Recovery Disk, or boot into install CD)
Utilities Menu : Terminal

From within Terminal window:
cd /Volumes/USB_Stick
hdiutil attach MacOSX10.7.4.dmg
cd /Volumes/MacOSX10.7.4
installer -pkg combo-updater.pkg -target /Volume/Your-HD-Internal

"Confirmed: only ThunderBolt 1.2 causes the kernel panics. (The other updates appear to work fine)."

This is absolutely not the case and while the 10.7.4 update may work for you, installing it across the board is bad advice.

Thousands of us - especially with older MacBooks - had to revert to 10.7.3 because of ongoing kernel panics. We did not install the Thunderbolt update. The problems were caused by the 10.7.4 update. Apple has yet to acknowledge the problem and release a fix. Go check the 10's of pages in the Apple forums for confirmation of this fact.

Hi, I've posted this yesterday and it has worked for those that tried it. There is some bad code in this update and it is breaking Lion for everyone. So, boot to Recovery HD by holding Command-R on a restart. Then select the option to reinstall Lion. It will verify your computer and reinstall via the internet. You will need an airport connection or a cable to your router. The reinstall will take about an hour and put you into 10.7.3. It will retain all your files and prefs. Nothing will be lost. Then go to software update and you will be offered 10.7.4 and a few other updates. Go ahead and do that. You will then be back where you were, and with a brand spanking new system. Going to software update again will offer you Thunderbolt and iPhoto. DON'T DO THAT! wait for Apple to come out with a fix. Good luck.

Can confirm the above. Do not install this update on a MacBook Pro 2011. You will get the message that the update cannot be installed and you will be asked to restart. The restart will fail and end in an kernel panic. Only the re-installation of OSX will bring the computer back to life.


Many people are having problems. Installing all the 6/11 updates trashed the Lion install on my MacBook Pro. Kernel panic on reboot. Suspicion is that it's the Thunderbolt update.
Check out threads on Apple discussion support Forums:

Lion recovery worked perfectly - but a big pain.


Yep - 20 minutes of panics till figured out what to do, followed by two long hours of painful re-installation of Lion. Come on Apple ...


Me too! 2nd reinstall of Lion. Wasn't sure what burped first time, 4 updates showed up.

Thunderbolt updates are very important in order to be able to use all your Thunderbolt devices like scanners, cams, printers...

Thunderbolt cameras? scanners? printers? I've not seen those. Would like to. But haven't. All I've seen are hardrives. Guess I'll do a search to see what I've missed out on.

I received an email from Apple concerning this update but it didn't show up under the Software Update menu. I wonder why?

I plan to install this. I ordered a Thunderbolt Display, and am kind of annoyed the the SHIP DATE was scheduled more than a month after purchase.

I should have it in 10 more days :|.

I suppose it might only show up in SU when the device is in active use?

Did you have your Mac connected to the Thuderbolt Display, while running SU?


No I don't. I just like keeping my MacBook Pro up-to-date.
