GarageBand 5.1 update
Apple today released the GarageBand 5.1 update, which it says addresses general compatibility issues, improves overall stability, and fixes a number of other minor issues along with an addressing an important security issue that allowed third-party to track usage of the app. According to the documentation, the specific issues addressed include the ability to add GarageBand track effects and Audio Units to a guitar track, improved support for Apogee audio interfaces, faster switching to full screen in Magic GarageBand, and improved access to audio monitoring settings. Apple says the update is recommended for all users of GarageBand ’09.
Separately in Apple's security bulletin, the company noted that update disabled the ability for third-parties to users' web activity via cookies: "When GarageBand is opened, Safari's preferences are changed to always accept cookies. The default preference is to accept cookies only for the sites being visited. The altered setting may allow third parties and advertisers to track a user's web activity," Apple wrote in documentation of the issue. "The update addresses the issue by not changing the preference setting. Users who have run previous versions of GarageBand should
confirm that their Safari preferences are set as desired."
