On the heels of the recent iMac refresh (see “New iMac Gains Thunderbolt, FaceTime HD, and Quad-Core CPUs,” 3 May 2011), Apple has released a couple of iMac-specific updates that address stability-related issues with several apps and interfaces, with a particular focus on Thunderbolt. Mac OS X 10.6.7 Update 1.0 for iMac (Early 2011) 1.0 introduces fixes that improve the reliability of Back to My Mac, App Store, and FaceTime, and corrects issues in Windows file sharing, graphics and video display, and the new Thunderbolt interface. The latter is also the main target of the iMac EFI Update 1.6, whose release notes mention no changes beyond Thunderbolt. But according to Other World Computing, the update also unlocks the full 6 Gbps SATA 3.0 capabilities of the two internal drive bays, though the optical drive bay remains at 3 Gbps. As always with firmware updates, do not disturb or power down your iMac while installing, since it could leave the Mac in a non-functional state. Both updates can be downloaded and installed via Software Update, or through their individual pages on Apple’s Web site. (Free, 382.56 MB and 6.1 MB respectively)
Find Text Leading from Acrobat PDF
Ever have to recreate a document from an Acrobat PDF? You can find out most everything about the text by using the Object Inspector, except the leading. Well, here's a cheesy way to figure it out. Open the PDF in Illustrator (you just need one page). Release any and all clipping masks. Draw a guide at the baseline of the first line of text, and one on the line below. Now, Option-drag the first line to make a copy, and position it exactly next to the original first line at baseline. Then put a return anywhere in the copied line. Now adjust leading of the copied lines, so that the second line of copy rests on the baseline of the second line of the original. Now you know your leading.
Or you could buy expensive software to find the leading. Your choice.

I just received my new 21.5" quad i7 iMac and was applying all the updates during setup. The iMac shipped with 10.6.6. A bunch of updates are available in Software Update including 10.6.7. Haven't tried anything from there yet. Instead I downloaded the 10.6.7 combo updater and it says that my system drive doesn't meet the requirements. Could it be the updater doesn't recognize the new iMacs yet?
With a new machine, I'd let Software Update do the work rather than rely on the combo updater, since it's unclear where in the timeline it was released.
