Mac OS 8 is now an app that you can download and install on macOS, Windows and Linux


Sluggish developer Felix Riesberg has turned Mac OS 8 into an app that you can install on your Mac or PC. After turning Windows 95 back into an app in 2018, Reisberg decided to convert the entire 1991 Macintosh Quadra into a single electron app with Mac OS 8.1. It even includes many apps and games, thanks to an old Macworld demo CD from 1997. The app can be installed on MacOS, Windows and Linux.

The Macintosh.js app is written entirely in JavaScript, and it uses a virtual machine to emulate the Macintosh Quadra 900 with Apple, the Motorola CPU used before IBM’s transition to PowerPC chips. Managed to get classic games like Rieseberg Duke nukem 3d, Civilization II, Dungeons & Dragons, i.e, Oregon Trail, Gully 19 Bowling, And Loss included Its going on. A set of apps and tests are also pre-installed, including Photoshop 3, Premier 4, Illustrator 5.5, Stuff It Expander and Apple’s Web Page Construction Kit.

While Internet Explorer and Netscape are preinstalled, versions are so old that Riesberg says, “You won’t open Google.” Either way, it is impressive that the 90s version of Mac OS is ported to run in JavaScript.

If you are interested in trying out the app, all standalone versions are less than 250MB and can be downloaded from GitHub. Enjoy, once again, a trip down memory lane.
