InfiniteMac is a browser-based emulator that allows users to run every version of classic MacOS from System 1.0 to MacOS 9.2.2, and even transfer files between their modern computer and the emulator.

For years, you’ve held onto those floppy disks and CD-ROMs, dreaming of the day you could fire up StuntCopter or revisit old WordPerfect files. But vintage hardware is finicky, and emulators often require technical wizardry. Enter InfiniteMac, a browser-based emulator that lets you run every version of classic MacOS—from System 1.0 to MacOS 9.2.2—with just a click.
This morning, I played Warcraft II for the first time since the 1990s. No hardware tinkering, no software hoops—just pure nostalgia, served up in a browser tab.
How InfiniteMac Works
- No Setup Required: Unlike traditional emulators, InfiniteMac runs entirely in your browser. No downloads, no configurations.
- Full Library of Classic Operating Systems: Choose from every MacOS version (and NeXT), customize RAM and screen size, and even load virtual CD-ROMs.
- Classic Software Access: InfiniteMac has native access to the Macintosh Garden, a collection of classic Mac software applications. InfiniteMac has a small collection of popular apps installed with each emulated operation system, but users can natively search and add additional software to their emulated environment at any time.
- Seamless File Transfer: Drag and drop files between your modern computer and the emulator. Still have old WordPerfect, System 7 sounds, or ClarisWorks documents? No problem.
Using InfiniteMac To Rescue Old Files

For longtime Mac users, InfiniteMac isn’t just a trip down memory lane—it’s a practical tool. Many of us have decades-old files trapped in obsolete formats. With InfiniteMac, you can:
- Rescue Old Documents: Open hundreds of old files types like MacPaint, ClarisWorks, KPT Bryce, or WordPerfect without hunting for vintage software.
On the desktop of the InfiniteMac emulation is a folder called “The Outside World.” You can use this folder to move your files in and out of InfiniteMac. For example, I can create documents in SuperPaint or KPT Bryce using the emulated apps and then move them back to my real computer. Any files that you add to the “Upload” folder will show up in your web browser’s default downloads folder.
The Community’s Verdict
Reddit users are raving about InfiniteMac. One Reddit thread calls it “the easiest way to relive the ’90s.” Others praise its speed and simplicity, especially compared to finicky hardware emulators. Besides recusing old Macintosh files, you can:
- Revisit Classic Games: Play Dark Castle, Bolo, or Oregon Trail as they were meant to be experienced.
- Preserve Digital History: Explore the operating systems that shaped modern computing.
Limitations and Quirks
- Occasional Crashes: Like the original systems, InfiniteMac isn’t flawless. Save often.
- Sound Issues: Chrome works best for audio-heavy programs.
- No Apple IIGS: A minor gripe for fans of Apple’s other classic systems.
A Dream Come True for Retro Mac OS Fans



InfiniteMac is more than an emulator—it’s a time machine. Whether you’re a retro gamer or just need to access old files, this tool bridges the gap between past and present. And for those of us who grew up with the “thunk” of a floppy disk, it’s a welcome reminder of simpler times.
