Apple Posts Important iMac SuperDrive Update -- Apple has released the iMac SuperDrive Update, the first of a series of SuperDrive firmware updates that are critical for owners of SuperDrive-equipped Macs. A bug in the firmware of Pioneer DVD-writing drives (such as the SuperDrive, though Apple doesn't use Pioneer drives exclusively) makes them unable to identify media belonging to a new specification for higher-speed DVD media. Using these discs, which record at 4x speed for DVD-R and 2x for DVD-RW, can potentially damage the drive itself: the device's laser attempts to determine what type of media has been inserted, and since it doesn't recognize the new format, it keeps trying until it overheats and burns out. (Macintosh author Jim Heid has published more detailed information at his Macintosh Digital Hub Web site.) So far, Apple has released an update only for the iMac G4 (15-inch Flat Panel), and only under Mac OS X; the company says that updates for the Power Mac G4, as well as Mac OS 9 versions for both types of machine, will be posted soon. Recent models, such as the 17-inch iMac G4, the SuperDrive-equipped eMac, and the Power Mac G4 (Mirrored Drive Doors), include the latest firmware version and are not affected by the problem. The iMac SuperDrive Update for Mac OS X is a 1.2 MB download. [JLC]
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.
