The Sophisticated Operating System,[1] or SOS (/sɔːs/),[2] is the primary operating system of the Apple III computer. SOS was developed by Apple Computer and released in October 1980.

In 1985, Steve Wozniak, while critical of the Apple III's hardware flaws, called SOS "the finest operating system on any microcomputer ever".[3]

The operating system designed for the Apple III computer was called "SOS". This title arose from the Apple III's code name, "Sara", which itself came from the name of the daughter of engineer Wendell Sanders.
