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)
Fun Way to Send Attachments in Mail
If you're working in a file that you want to attach to a message in Apple Mail, you can transfer the file to Mail easily: From the title bar of the file's window, drag the little proxy icon to Mail's icon on the Dock. Your Mac will make Mail the active application and open a new outgoing message, with the file attached.
(If your icon won't drag, the file probably isn't saved.)
