Gigging musicians will be pleased to hear that Apple has updated MainStage, the live performance program that's part of Logic Studio. Version 2.1.1 provides over 40 minor bug fixes and performance tweaks, including enhanced support for 32-bit Audio Unit Bridge plug-ins, improved stability when changing or removing audio devices, and the resolution of a bug that caused audio output loss when the user enabled "Display audio engine overload" messages. The update also improves screen controls in several areas, increases the reliability of number keys acting as command triggers, and restores proper behavior to several aspects of the Loopback plug-in. The lengthy release notes are available in a Knowledge Base article on Apple's Web site. The hefty update is available via Software Update and Apple's Support Downloads page. (Free, 207 MB)
Open Files with Finder's App Switcher
Say you're in the Finder looking at a file and you want to open it with an application that's already running but which doesn't own that particular document. How? Switch to that app and choose File > Open? Too many steps. Choose Open With from the file's contextual menu? Takes too long, and the app might not be listed. Drag the file to the Dock and drop it onto the app's icon? The icon might be hard to find; worse, you might miss.
In Leopard there's a new solution: use the Command-Tab switcher. Yes, the Command-Tab switcher accepts drag-and-drop! The gesture required is a bit tricky. Start dragging the file in the Finder: move the file, but don't let up on the mouse button. With your other hand, press Command-Tab to summon the switcher, and don't let up on the Command key. Drag the file onto the application's icon in the switcher and let go of the mouse. (Now you can let go of the Command key too.) Extra tip: If you switch to the app beforehand, its icon in the Command-Tab switcher will be easy to find; it will be first (or second).
