Emulator for Mac OS 9 in OS X updated for Mountain Lion

By John Rizzo

Jon Gardner has posted an updated version of preconfigured SheepShaver/Chubby Bunny emulation software, which enables the old Mac OS 9 to run on OS X Intel Macs. Gardner says this update runs on OS X 10.8. SheepShaver is an open source emulator, and Chubby Bunny contains the ROM file of a pre-PowerPC Mac as well as a preconfigured Mac OS 9.0.1 installation.

Gardener describes the new version:

I'm the Jon who submitted the customized, preconfigured SheepShaver/Chubby Bunny setup mentioned at your page Running Mac OS 9 apps on Intel Macs.

There's a newer version here that includes the updated SheepShaver (the recommended 15-07-2012 build). I'm currently running this setup on a MacBook Pro with Mac OS X 10.8.5, so I'm pretty confident that it'll run on the latest and greatest Apple hardware. It should also run on PowerPC machines, but I haven't tested that. I'd love to hear from anyone who does.

If you've tried Gardner's new Chubby Bunny bundle .

Although the Chubby Bunny bundle includes Mac OS X 9.0.1, SheepShaver can run Mac OS 7.5.2 (known as "System 7" at the time) through Mac OS 9.0.4. Sheep Shaver is available at the, along with documentation. (And there's also a version that runs on Windows.) However, you will need your own 680x0 Mac ROM file, which are not easy to come by, and the installation and setup is complicated. The Chubby Bunny bundle gets around these issues.

I'm not pretending that this is productivity software. We are in the realm of the hobbyist and the Mac historian here. We're talking retro coolness.

Along those lines, Gardner also reported on another emulator that allowed Mac OS 9 to run on an iPhone or iPad:

BTW, the Mini vMac emulator for iPhone stopped working a couple of iOS versions ago, so it's not possible to run a Mac Plus virtual machine on the current iOS. I know...bummer.
