Mac OS X 10.0 "Cheetah" ( Cheetah ) is the first major release of macOS , the desktop operating system from Apple that was introduced at that time under the name of Mac OS X. With it, the previously used Mac OS "Classic" was completely replaced. After a public beta phase, it was offered on March 24, 2001 at a price of DM 329 (adjusted for inflation in 2020 corresponds to around € 425). For buyers of the public beta , the price was reduced to 79 DM (2020: ≈ 102 €).

Mac OS X, spoken in English Mac OS Ten for the number ten , follows Mac OS 9 and is the result of the merging of the classic Mac OS with the OPENSTEP operating system purchased by NeXT in 1996 or its further development Rhapsody .

As Mac OS X Server 10.0 , it also replaces Mac OS X Server 1.x, which is almost identical to Rhapsody and which inherited the classic Mac OS as a server operating system as early as 1999.

The successor, Mac OS X 10.1 "Puma", was released on September 25, 2001.
