SheepShaver is a PowerPC (PPC) emulator which allows you to run Mac OS 7.5 up to Mac OS 9.0.4 on various platforms, such as on Windows. SheepShaver started as a commercial project in 1998 but is now open source since 2002. SheepShaver is not perfect (it cannot run MacOS 9.1 or 9.2), but enables users to run the vast majority of PPC software for Macintosh on their PC, which is all things considered, extraordinary, especially back in the year 1998.

This bundle was put together by 'that-ben' and is intended to be the easiest possible for starters. It already contains a compatible ROM file (Mac_OS_ROM.rom), a ready 250MB disk image on which Mac OS 9.0.4 is already fully installed (as well as an optional empty 30GB, yes 30 gigabytes, disk image to accomodate heavy disk space use). Please note that the 250MB base image is not intended for users to install more software. If you intend to install software in your SheepShaver VM, then you will need to expand that blank 30GB file and move your Mac OS 9.0.4 installation to it.

Pre-installed software includes: QuickTime 4.1 for multimedia playback, Stuffit Deluxe 7.0.3 for extracting/compressing Stuffit archives and MacBinary files (such as .sit, .hqx or .bin), Toast 5 Titanium for mounting/creating CD images (such as .iso or .toast), Virex 6.1 which was the best antivirus for Mac around year 2000, SoundApp which is an extraordinary compatible music player (plays close to 100 different formats such as .mp3, .wav or .mod) and a bunch of useful utilities such as Super ResEdit 2.4, DiskCopy 6.4 and TaskMenuBar 2.4.2.

ON WINDOWS:YOU NEED TO INSTALL GTK+ BEFORE USING SHEEPSHAVER :)RTFM: https://www.emaculation.com/doku.php/sheepshaver_setup

ON MODERN MAC OS X: If it does not work (especially under Mac OS X 10.15 Catalina), please replace the executable application file by the one in the downloads mentioned 'NOTARIZED - Catalina 10.15'. RTFM:https://www.emaculation.com/doku.php/sheepshaver_mac_os_x_setup

For Windows: All you need to do is unzip the file, follow the instructions file inside the '1 - Install First' folder and you'll be ready to run old Mac software in seconds.

For Mac: All you need to do is set the 'Unix Root' folder you see on the VM desktop, it allows you to share files between Mac OS X and the VM Mac OS. It's fine if you do not set it, but know that it's gonna default to your /Users/your-username/Documents/ until you set it elsewhere.

SheepShaver is crashing while booting Mac OS 9? If the VM crashes while booting, try to re-launch it another time. This happens with SheepShaver, it's not 100% stable and sometimes extensions loading while the virtual Mac OS is booting can crash SheepShaver, notably the Virex antivirus extension. Re-launching it often bypasses the issue.

SheepShaver crashes when booting Mac OS 8.1? You need the Old World Mac ROM listed separately (see the downloads). Shut down SheepShaver if it's running, then launch the SheepShaverGUI and under the Memory/Misc tab, select that Old World Mac ROM file, then start SheepShaver and it should boot Mac OS 8.1 successfully.
