July 22, 1997: Apple unveils Mac OS 8, its next-gen operating system. The first major OS refresh for Macintosh since System 7’s release in 1991, it’s destined to become a big hit with users.

Mac OS 8 introduces easier surfing of the internet, a new three-dimensional look and other features. It gets great reviews — but arrives at a very challenging time for Apple.

March 8, 1997: Apple renames the forthcoming Mac OS 7.7 update, calling it “Mac OS 8.” It’s more than just a name change, though: It’s a sneaky sucker punch that ultimately knocks out Mac clones.

Unfortunately for Mac users, the updated operating system does not deliver the total top-to-bottom rewrite promised by Apple’s Project Copland. However, the renaming strategy turns out to be a brilliant (if underhanded) way of getting Apple out of terrible licensing deals.

Anyone wanting a serious dose of nostalgia should install a just-released emulator of a classic Apple desktop computer running Mac OS 8, first released in 1997. There’s even a bunch of games and productivity applications from the same era.

Because phones are small, it’s easy to underestimate how powerful they are. Give an iPhone a larger display and it would make a fine desktop PC. Case in point: A new video shows an iPhone X running Mac OS 8.1 as well as a couple of games.
