The Apple Macintosh 1.0 was released in 1984, and it was partially based on the Apple Lisa. Steve Jobs joined the Macintosh team after he was forced out of the Lisa project.
The interface icons were designed by Susan Kare. Kare was a pioneer of pixel art. Her designs included some of the classic Apple icons, such as the Smiling Mac, paint bucket and lasso tool. She also designed the Chicago, Monaco and Geneva typefaces which have been used in Apple computers. The Macintosh 1.0 icons and interface are very similar to those of Apple Lisa and they were also influenced by the design of the Xerox Alto.
