Mac System Software 6.0.6 is a version of Mac System Software 6.x which was released in September 1990. However, distribution was quickly halted due to an AppleTalk bug which would crash the entire system, therefore the system was quickly replaced with System 6.0.7. This is the first version of Mac System Software 6 to support Macintosh LC, Macintosh Classic and Macintosh IIsi.
