Apple has released a firmware update for the SuperDrive in the Power Mac G5 and eMac.
The 2MB update delivers improves reliability when accessing DVD and CD media, says Apple.
The update comes a day after Apple announced that its new Power Macs would ship with speedier SuperDrives. The new 16x SuperDrive now supports double-layer DVD+R DL discs.
While single-layer DVD-R discs hold up to 4.7GB of data, double-layer discs have two layers of data, allowing the SuperDrive laser to read and write on either layer, almost doubling the storage to 8.5GB.
