Apple has released two updates - Carbon Sound Manager Update 6.0.2 and Power Mac SuperDrive Update 1.0 for Mac OS 9.

The 1.2MB Sound Manager update improves reliability and performance of a number of applications that use Carbon Sound Manager.

The SuperDrive update installs new firmware on SuperDrives running Mac OS 9, addressing an incompatibility issues with 4x DVD-R and 2x DVD-RW media. It also enables the ejection of audio CDs that are copy-protected or contain mastering errors.
The update is for 4x DVD-R or 2x DVD-RW media in a Power Mac G4.
