There is no such thing as Mac OS X 10.7.3. However, I'm sure you intended OS X 10.7.3. Unfortunately, your link provided offer no information regarding tapsaite's problem.
@tapsaite; it might be helpful to repost your problem with a more meaningful title. I don't know anything about this particular issue. But something along the lines of '10.7.3 update HDMI/Thunderbolt broken' might key in the people that have similar problems. They may have a solution.
Unfortunately, your source is out of date.
It's just OS X, now. This will be corrected, in a future software update. It's helpful to stay current, when providing information to others.
I'm afriad that you completely missed the point of tapsaite's question. Whiile spending the majority of your reply correcting his quibble of an error in Apple's OS naming schema, the link, to the release notes that you provided, referenced nothing about the main thrust of his post (possible Thunderbolt issues). The ability to distinguish between general questions and the specific concern matters a lot, to people seeking information. We do our best to reach them on the level that helps them the most. Having a basic grasp of grammar is also prefered.
