Reverting to release notes that make haiku seem wordy, Apple has released something called OS X Mountain Lion 10.8.2 Supplemental Update 2.0 that claims to address “an issue with Keychain that can affect 2012 Mac systems.” It’s recommended for all Macs introduced in 2012, but there’s nothing else that hints at what it fixes or how serious the “issue” might be. It’s available via the App Store’s Updates screen, and if it doesn’t appear for you, it’s presumably not necessary for your Mac. (Free, 26.65 MB)
Copy Excel Selection as a Picture
Want to show someone a chunk of an Excel spreadsheet via email or iChat? You could take a screenshot, but if you want to show just a portion of the Excel window and you don't use a utility like Snapz Pro, you can do this right from within Excel 2008. Make a selection, hold down the Shift key, and choose Copy Picture from the Edit menu. You can select whether the selection will be rendered as though it was shown on screen or as though it was printed. Then just switch to your desired destination and paste.
