Apple Pulls ThunderBolt 1.2 Update due to Boot Problems w/some 2011 Macs:
A new Apple doc today (6/15/2012) confirms a reader's warning on problems booting 2011 MBP after T'Bolt 1.2 update posted early this week. (He was not alone & repeatable after restore/reinstall.)
Here's a copy of Apple's doc with some recovery tips. (Original TBolt Update 1.2 was pulled.)

"Mac is unresponsive on startup after installing Thunderbolt Software Update 1.2

Products Affected:
Mac mini (Mid 2011), Mac mini Server (Mid 2011), MacBook Air (11-inch, Mid 2011), MacBook Air (13-inch, Mid 2011), MacBook Pro (13-inch, Late 2011), iMac (21.5-inch, Late 2011), iMac (27-inch, Mid 2011)

Symptoms:
You may notice your Mac becomes unresponsive on startup after installing Thunderbolt Software Update 1.2.

Resolution:
Apple has identified an issue with Thunderbolt Update 1.2 (released Monday, June 11th, 2012) which caused some Macs to become unresponsive on startup after the update was installed. Apple promptly withdrew the update and investigated, discovering an installation compatibility issue with a previous Thunderbolt update applied by some customers. Apple apologizes for the disruption this caused for customers with affected Macs.

Thunderbolt Software Update 1.2 enables Mac computers to support the Thunderbolt to Gigabit Ethernet Adapter. If you do not plan to use this adapter, you do not need to install the update.

To recover a Mac computer that will not start up after installing Thunderbolt Software Update 1.2, start up in Lion Recovery by pressing and holding the Command and R keys after hearing the start up chime. Reinstall Mac OS X. Reinstalling Mac OS X using Lion Recovery does not remove any personal data or files from your Mac.

Alternatively, you may perform either of these options:

  1. Restore from a Time Machine backup that was created before Thunderbolt Software Update 1.2 was installed.
  2. If you have access to another Mac, you can start up the affected Mac in Target Disk Mode and then install the OS X Lion v10.7.4 Combo Update to resolve this issue quickly.

Additional Information:
Apple is investigating this issue and plans to release a new version of Thunderbolt Software Update 1.2 soon."

Although ThunderBolt Update 1.2 was said to only add support for the new ThunderBolt to GigaBit Ethernet Adapter (for 2012 Macs w/o an Ethernet port), some may have installed it in case it had any other improvements. (On that subject, Tuesday's news has Apple's notes on the ThunderBolt to Ethernet Adapter not supporting sleep w/2011 Mac Minis. I wondered if that also applied to other 2011 Macs.)

Update: Late Monday night (June 18th), Apple posted Thunderbolt Software Update 1.2.1. But again, although v1.2.1 is supposed to fix the above problems - if you do not have a need for the Thunderbolt to Ethernet adapter, I would not install this update. (And even if I did need it, I'd wait for some feedback from early adopters first.)
