General information

What is SheepShaver?

SheepShaver is a MacOS run-time environment for BeOS and Linux that allows you to run classic MacOS applications inside the BeOS/Linux multitasking environment. This means that both BeOS/Linux and MacOS applications can run at the same time (usually in a window on the BeOS/Linux desktop) and data can be exchanged between them. If you are using a PowerPC-based system, applications will run at native speed (i.e. with no emulation involved). There is also a built-in PowerPC emulator for non-PowerPC systems.

SheepShaver is distributed under the terms of the GNU General Public License (GPL). However, you still need a copy of MacOS and a PowerMac ROM image to use SheepShaver. If you're planning to run SheepShaver on a PowerMac, you probably already have these two items.

CVS snapshots and precompiled binaries

Anonymous CVS access

Because SheepShaver shares a lot of source files with Basilisk II, you also need to checkout the Basilisk II sources.

To download the current version of the sources via CVS:

$ cvs -d :pserver:anoncvs@cvs.cebix.net:/home/cvs/cebix login
(password is "anoncvs")
$ cvs -d :pserver:anoncvs@cvs.cebix.net:/home/cvs/cebix checkout BasiliskII
$ cvs -d :pserver:anoncvs@cvs.cebix.net:/home/cvs/cebix checkout SheepShaver
$ cd SheepShaver
$ make links

You can then try to compile the program with

$ cd src/Unix
$ ./autogen.sh
$ make

under Linux, or

$ cd src/BeOS
$ make

under BeOS.

A Web interface to the CVS repository is also available.

Frequently Asked Questions (FAQ)

Didn't I already see this years ago?

Yes, SheepShaver originally appeared for BeOS in 1998 as a commercial application (first as shareware, then via the now long-defunct BeDepot). Due to the demise of Be, it has been re-released in 2002 as Open Source software under the GPL.

Can I run MacOS X applications under Windows with this?

No. Firstly, SheepShaver doesn't run under Windows. Secondly, MacOS X doesn't run under SheepShaver.

Will you make a Windows version?

I'm not a Windows programmer.

What's with the silly name?

It's a pun on “ShapeShifter”.
