Apple has posted the iMac SuperDrive Firmware Update for Mac OS 9, as noted by MacUpdate. The update addresses an incompatibility with 4x DVD-R and 2x DVD-RW media when used with the internal SuperDrive found in the 15″ flat-panel iMacs, and also fixes a problem with ejecting audio CDs that are copy-protected or have mastering errors. The previously released Power Mac G4 and iMac SuperDrive updates for Mac OS X can be found here.
