Get a Mac OS 8 Emulator and Relive the Macintosh 90s

Mac OS 8.1 emulator

If you’ve been a longtime Mac user, you may fondly remember the classic Mac OS system software releases. Rather than get stuck in a memory, you can relive some nostalgia by running Mac OS 8.1 on your modern Mac right now (or even on a Windows PC or Linux machine), and it’s as easy as launching any other app.

Macintosh.js is a self-contained Electron app that bundles a classic Mac OS emulator preinstalled with Mac OS 8.1 along with a handful of classic applications from that era, including Adobe Photoshop 3.0.5, Adobe Illustrator 5.5, demos for Duke Nukem and Civilization 2, Oregon Trail, and more.

  1. Get Macintosh.js from the developers GitHub page here
  2. Unzip the downloaded archive and launch “” to get started

The Macintosh.js experience should feel immediately familiar to anyone who used the classic Mac OS releases of the pre-Mac OS X era. And if you didn’t, well it’s a pretty simple and intuitive point-and-click user interface.

System startup is identical and fairly speedy, and most apps launch impressively fast in the emulator, many even faster than their modern app equivalents (which are now obviously much more sophisticated, but that’s still kind of amusing).

And a classic computing experience wouldn’t be complete without frequent system crashes and reboots, and you can experience those in Macintosh.js too! Remember the “Sorry, a system error occurred” bomb alerts and CHK errors? Play around enough and you’ll run into those again too.

You can even transfer your own apps and files between Macintosh.js with Mac OS 8 and your modern Mac (or PC), so if you want to stuff ResEdit or some other old school app or game on their you are free to do so. Don’t forget you can download old classic Macintosh software from a variety of repositories if that appeals to you.

Perhaps the only disappointment is that internet connectivity doesn’t work with Macintosh.js, not that using Netscape Navigator, Archie, or Mosaic would be wonderful experiences, but it’d certainly help to complete the retro experience.

The developer of Macintosh.js also built the popular Windows95.js app, which bundles Windows 95 as a self-contained application in a similar manner and is also a fun digital toy to play around with if you want to recreate the old beige box PC feeling.

By the way, if you don’t feel like downloading or installing an application onto your Mac, you can also run classic Mac OS releases in a web browser too.

If this kind of thing appeals to you, don’t miss checking out other nostalgic computing stuff in our retro archives.

    This only runs on Big Sur as far as I can tell. Are there versions for Catalina?

    @JohnIL, Wait,the github page notes the “real internet” can’t be reached. Why are you pontificating about not working on modern websites? Does the web sharing server actually work? Also Apple had a decade of coding and hardware modification before they switched to PowerPC. The Model-T isn’t a good comparison. Imagine driving a 60’s Cadillac instead. In a number of settings it’s ride is superior, partly because of lack of fuel-saving and modern safety requirements. Using an old browser can be like that, too.

    I certainly don’t see things that way. I loved Cyberdog back in the day, the seemless integration of browser, email, ftp, fidonet, etc. The closest modern experience is Chrome integrated with Gmail and Search and the rest. Here’s a somewhat related story: Back around this time, at local libraries there were strict filters that were overzealous. Searching for stuff about the author Pillip K Dick, for example, got blocked. But they also had an Internet Poetry Database that used the Lynx textbrowser for its interface. I could get to the address bar by searching for a nonsense string of characters instead of a poem title or poet name. Then I could redirect the browser away from the poetry database, to any website I wanted. Now, I’m not going to explain exactly how you can find clever hacks or find vulnerabilities with Mac internet software, but you can get to “deep code”, and peek behind the curtain. The game involves getting verbose error messages wen a modern bit of code crashes the browser or app. Just a thought!

    Nice to see old technology but then you realize it has no place in today’s world. Much like the 56K modem would be useless with today’s complex web sites. The ideal of loading a old operating system is like visiting a museum of old model T cars. Fond memories for sure, but I wouldn’t want to drive one on the freeway.

    Can I run Appleworks 6.0 or Clarisworks?

    Oh to see that beautiful Netscape page loading icon again – I always loved the design with the shooting star or whatever it is but grew to hate the app. Fun thing with this emulator is you can save modifications – I noticed how all the extensions and control panels are enabled – screams NEWBIE Mac user lol

    I wonder if I can get Kaleidoscope on this thing. (This allowed complete modification of the GUI, to some horrendous results dependent upon taste, of course)

    Oh btw there is no scrolling – this is before scrolling existed in Mac OS

    Thanks but I have enough challenges as is.

    Seeing those old screens is like meeting with your old school friends :) but as a sysop at the time, I remember OS 8 as a pretty bad system :) Os 8.5 was really good…fond memories come with that one.

    I hate to say it, but this almost appeals to me to run the drivers for my over-priced Xerox printers — I have a Xerox Phaser 5550DN and a Phaser 7760GX (color).

    Xerox hasn’t updated these drivers since Mac OS X 10.10 Yosemite.

    If you know of any full-featured drivers that work, I’d love to hear.
