Hobbyists have set about making classic versions of macOS available on modern devices in the past, such as the Internet Archive's collection of classic Macintosh software that can be emulated in a browser. We may eventually support M1 Macs, but not at this time.

Mac OS 8 was the remnant of Copland OS, and is credited with helping to modernize Mac OS while Apple developed Mac OS X. Our Mac builds may run through Rosetta, but you WILL encounter various issues that we wont provide support for. Mired by delays, missed deadlines, and dysfunctional management, Copland was never commercially released and is regarded as one of the biggest IT project failures in history. Originally released in 1997, Mac OS 8 represented a significant overhaul of classic Mac OS software, and integrated many of the technologies developed for Apple's cancelled Copland OS.

Although Internet Explorer and Netscape are preinstalled, Rieseberg says the versions are so old that 'you wouldn't be able to open even Google.' The app can also run classic games such as Duke Nukem 3D, Civilization II, Dungeons & Dragons, Namely, Oregon Trail, Alley 19 Bowling, and Damage Incorporated. The macintosh.js app includes a number of apps and games from a 1997 MacWorld demo CD, and includes Photoshop 3, Premiere 4, Illustrator 5.5, StuffIt Expander, and Apple’s Web Page Construction Kit. The project has not been approved by Apple and is provided for educational purposes only. The app, titled 'macintosh.js,' is written entirely in JavaScript, and uses a virtual machine to emulate a Macintosh Quadra 900 with a Motorola CPU that Apple used before its transition to IBM's PowerPC architecture.

Having previously transformed Windows 95 into an app in 2018, Rieseberg turned his attention to transforming an entire 1991 Macintosh Quadra with Mac OS 8.1 into a single Electron app. Slack developer Felix Rieseberg has transformed Mac OS 8 into a single downloadable app for modern macOS, Windows, and Linux devices. Mac OS 8 is now available as an app for macOS, Windows, and Linux, reports The Verge.
