Apple is shipping new Power Mac G4 systems with Mac OS 9.2.1, according to ThinkSecret, which notes that the update provides bug fixes and other minor improvements. Mac OS 9.2.1 will be available to download in the coming weeks, according to the site, although it’s unclear if this update will be for all Mac OS 9 users or just those that already have Mac OS 9.2. Apple has yet to release Mac OS 9.2 for general consumption.
