Macintosh is a brand, referred to as Mac, which is a series of personal computers from Apple Computer.
Macintosh was named by Jeff Raskin, the founder of the Macintosh project, after his favorite apple variety, Mcintosh, but in order to avoid conflicts with the audio equipment manufacturer McIntosh Labs Laboratory)'s name was in conflict, and he deliberately changed the spelling of the letters.
Extended information:
In 1979, Apple developed the Lisa, the successor to the Apple II, but at that time the product development team had not yet decided to use a graphical user interface. The Macintosh was a four-person research project at the time, before it even caught Steve Jobs' attention. It wasn't until late 1979 that Jobs visited Xerox's Palo Alto Research Center, giving Apple a fresh start to revolutionize the personal computer.
On several visits to Xerox PARC, Jobs and several other Apple employees saw the Xerox Alto computer in action. You could say it was an eye-opener for them.
The Alto computer has icons, windows, folders, a mouse, pop-up menus, a WYSIWYG (What You See Is What You Get) text editor, an Ethernet-based local network, and a network-based of prints and games. The concepts of "cut, copy and paste" and the Smalltalk programming environment were also demonstrated to Jobs and others one by one.
