Macintosh operating systems The family of Macintosh operating systems developed by Apple Inc. includes the graphical user interface-based operating systems it has designed for use with its Macintosh series of personal computers since 1984, as well as the related system software it once created for compatible third-party systems.
Compatible Time-Sharing System The Compatible Time-Sharing System (CTSS), was one of the first time-sharing operating systems; it was developed at the MIT Computation Center. CTSS was first demonstrated in 1961 and was operated at MIT until 1973. During part of this time, MIT's influential Project MAC also ran CTSS, but the system did not spread beyond these two sites.
