The Macintosh was introduced in 1984 and was the first commercially successful personal computer to feature a mouse and GUI. It helped popularize home computing. Throughout the 1990s, Mac faced competition from Windows but was revitalized by the 1998 iMac. The iMac sold over 800,000 units quickly and its design was applied to other Apple products. Mac transitioned to Intel processors in 2006 and continues to gain market share, now offering various products like the MacBook, iMac, Mac Pro, and more running macOS.
