MacBook Air and MacBook Pro Update 2.0 [just released]

Installed it on my MBP10,1 and so far so good. Build number is now at 12C3006 (was 12C60).

Wow, I hadn't noticed the build number changed. We have a few Late 2012 models on order so we can create our Mountain Lion image (forked of course until the 10.8.3 Combo is released). It'll be interesting to see what the different models end up with after they've been fully updated. :)

FWIW, there's a few posts on "macupdate.com" about problems with this firmware. I know, nothing new there, but just an FYI. Apple's had a few so-so releases in the last 12 months...
I'll be applying this later to a couple of Macs to test.

just installed it. intel and nvidia drivers are revved, UI seems a little snappier.

Ok, I will test next week, hopefully won't cause problems on earlier models. :)

No issues here
