SheepShaver is a PowerPC emulator that runs under Mac OS X.

But even there – even on an Intel machine, even under Snow Leopard – I can run an older Mac OS, enjoy my older applications, and read and edit my older documents, by using SheepShaver. But all of that is a lot of trouble, because I’m not usually using those machines I’m usually using my Intel-based Mac mini, and running Snow Leopard. I also have two PowerPC-based Macs that run Tiger and therefore have Classic. For certain applications that won’t run properly even under Classic, I have several ancient (by computer standards) machines that can actually boot into Mac OS 9. If, like me, you still have an older application or document that you’d occasionally like to open, what can you do? I actually have three different approaches. Classic reached the end of its life in Mac OS X 10.4 Tiger later versions of Mac OS X don’t include Classic, and Classic doesn’t run on Intel machines at all. But this solution was fated not to last forever.

To solve this problem, Apple tided its users over with Classic, an environment that emulated Mac OS 9 within Mac OS X. Were users doomed to lose access to all their older applications and documents? Recent Mac OS 9 applications that had been “Carbonized” might run natively under Mac OS X, but older applications certainly would not. Mac OS X was a completely different operating system from its predecessors (Mac OS 9, Mac OS 8, System 7). In the run-up to the original release of Mac OS X, users were justifiably worried about compatibility.
