## What it is
Basilisk II and SheepShaver are open-source emulators that run classic Macintosh operating systems on modern hosts. Basilisk II emulates 68k Macs running MacOS 0.x through 8.1, while SheepShaver runs PowerPC MacOS 7.5.2 through 9.0.4.

## Use cases
- run classic Mac OS software on Linux
- emulate a 68k Macintosh on Windows
- play old Mac games on macOS
- run PowerPC Mac apps on an Intel or Apple silicon Mac
- preserve and test legacy Macintosh software
- set up a retro Mac environment with a ROM image

## When to choose
- you need to run classic MacOS 0.x-9.0.4 applications on a modern OS
- you want an open-source, cross-platform Mac emulator
- you have (or can obtain) a Macintosh ROM image and MacOS copy

## When to avoid
- you need to emulate Mac OS X or newer macOS versions
- you want a turnkey solution without sourcing ROM images and OS installs yourself
- you need actively developed features - consider the kanjitalk755 fork instead
