Firmware Update Solves Power Mac G5 1.8 GHz Freezes -- Last week, a reader wrote in asking if we knew anything more about the freezing problems he was having with his single processor Power Mac G5 1.8 GHz. Almost simultaneously, Apple released a firmware update for that machine that promises to address a number of freezes, enabling us to write back and tell him that we'd looked into the problem, contacted Apple, and that they had dropped everything to release a firmware update for us. Every now and then you just have to take credit for utter coincidences! There are separate updates for Mac OS X 10.3.9 and 10.4.3; they're about 1 MB in size. [ACE]
Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
