Which came first, email or the Macintosh?

email came first, by 13 years. Ray Tomlinson sent the first message between two computers and chose the @ sign.

Side by side

email

Messages had been left for other users of the same machine since the mid-1960s. What Tomlinson did in 1971 was send one between two different computers on ARPANET, and pick @ to separate the user from the host because it was the only preposition on the keyboard that could not appear in a name. He did not record the first message and later said it was probably "QWERTYUIOP" or similar. Email is eighteen years older than the Web.

the Macintosh

The Macintosh launched in January 1984 with a graphical interface and a mouse, and beat Windows to market by almost two years. Neither invented the idea — Xerox PARC had built the Alto in 1973, and both Apple and Microsoft were working from what they had seen there. Mac OS X, the ancestor of today's macOS, arrived much later in 2001 and is Unix underneath.
