Late Monday, Apple released its Thunderbolt Software Update 1.2 firmware upgrade for its Thunderbolt-equipped Macs running Mac OS X 10.7 (“Lion”). The update, a 510 kilobyte download, adds support for the Apple Thunderbolt to Gigabit Ethernet Adapter.
In addition to the direct download, Thunderbolt Software Update 1.2 is available through Mac OS X’s built-in Software Update feature. The update requires a Thunderbolt-equipped Mac running Mac OS X 10.7.4 or later to install and run.
If you’ve tried the update and noticed any changes, please let us know in the comments.

It was a disaster. The update caused an unending kernel panic. The OS had to be reinstalled. Sadly, I took it to an Apple Authorized agent and had to pay for the service. Apple is not likely to make good on such costs, even though they are clearly responsible.
