System 6.0.1

System 6.0.1 (Finder 6.1, System Software Update 6.0.1) was released on September 19, 1988, and was pulled from distribution two weeks later. It was created to support the Macintosh IIx (1988). However, numerous bugs were found during initial seeding, the most prominent being bad spacing of screen fonts, and the Macintosh IIx came bundled with System 6.0.2 in its stead.
