It has been over a week since the Apple Developer Center Web site went offline, with no indication of when it will be fully back. However, Apple has created a status page displaying an itemized checklist of what services are online. (Alas, you can’t click the icons to bring services up and down!) In email to developers, Apple announced that it is prioritizing the order in which updated systems will be made available. Certificates, Identifiers & Profiles, Apple Developer Forums, Bug Reporter, pre-release developer libraries, and videos will be available first, followed by software downloads and remaining systems. (Most Developer Center systems have since come back online.)follow link
View Extra Audio Details in Snow Leopard
In Snow Leopard, Option-clicking the Volume icon in the menu bar displays a list of sound input and output devices. Choose one to switch to it; it's much easier than using the Sound preference pane. Also, hold Shift and click the icon to set the system volume, which is separate from the general output volume.
