## What it is
Infinite Mac is a browser-based emulator of classic Macintosh computers (System 1 through Mac OS 9 and early PPC Macs), built on WebAssembly ports of emulators like Basilisk II, SheepShaver, and Mini vMac. It loads pre-built disk images instantly and provides a large library of classic Mac software at infinitemac.org.

## Use cases
- run classic Mac OS in a browser
- try System 7 or Mac OS 9 without old hardware
- play retro Macintosh games online
- explore vintage Mac software library
- emulate old Macs for nostalgia or demos
- access KanjiTalk Japanese Mac environment

## When to choose
- you want instant, zero-install classic Mac emulation in a browser
- you need a curated library of vintage Mac software ready to run
- you want to share links to specific classic Mac OS experiences

## When to avoid
- you need high-accuracy emulation for software preservation research
- you want to emulate modern macOS or non-Mac systems
- you need native performance for demanding classic Mac applications

## Facets
- artifact type: application
- maturity: active
- function: simulation, wasm, gui
- domain: gaming-tools, developer-tools, cross-platform
- platform: wasm, browser
