In response to a customer's query about the underwhelming Mac Pro update released this week (see "Mac Pro Gains Only Minor Speed Bump, Not Thunderbolt or USB 3.0," 11 June 2012), Apple CEO Tim Cook replied by email that Apple is indeed working on a more substantial update to the professional tower Mac. Cook writes, "Although we didn’t have a chance to talk about a new Mac Pro at today’s event, don’t worry as we’re working on something really great for later next year." Macworld confirmed with Apple that the message was indeed from Cook. follow link
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-]).
