Apple has released a minor update to the Mac version of GarageBand. Version 6.0.2 reportedly improves overall stability, but most notably it introduces support for opening projects created in the iPad version of GarageBand (see “GarageBand for iPad and Mac Not Yet Ready to Play Together,” 11 March 2011). When you first open an iPad project after installing this update, GarageBand on your Mac will need to download an additional update that’s just shy of 200 MB. Note also that when you open iPad GarageBand projects, you’ll immediately be prompted to save them under a new name. That’s because once you’ve modified a project in the desktop edition, it can no longer be opened by GarageBand for iPad. ($14.99 new on the Mac App Store, free update, 47.44 MB)
Option-click to Hide Apps Quickly
This trick has been available in the Mac OS for years, but many people still don't know it. If you have too many windows cluttering up your screen, you can hide specific ones easily as you work. When you're in any application, hold down the Option key and click on another app's window, on the Dock, or in the Finder to switch to that other app and simultaneously hide all the windows in the previously current app.
