SheepShaver is an open source PowerPC MacOS run-time environment. That is, it enables you to run PowerPC Classic MacOS software on your computer, even if you are using a different operating system. However, you still need a copy of MacOS and a PowerMacintosh ROM image to use this program. SheepShaver is distributed under the terms of the GNU General Public License (GPL).
If you are using a PowerPC-based system, applications will run at native speeds (i.e. without any emulation involved). On other systems, SheepShaver provides the first PowerPC G4 emulator, though without MMU, to enable the execution of MacOS Classic. Performance with the current CPU emulator using basic just-in-time (JIT) translation techniques is roughly 1/8-th of native speeds.
The following platforms are currently supported: Linux (i386, ppc, x86_64), MacOS X (i386, ppc), Darwin, NetBSD 2.0, FreeBSD 5.3 and Windows for x86. An experimental port to MacOS X 10.4.4 for Intel is now available.

If SheepShaver (catchy name) is getting 1/8 of native speeds, how slow are the PPC apps using Rosetta? Lower than 1/8 of native speeds? Ouch if true.
It doesn’t run OS 9.1 or 9.2 though!
1/8th native speed sounds rough but it may be just fine. The machine I was using when I purchased most of the “classic” applications that I still need was a 292MHz Wall Street Powerbook G3, if I get a 2GHz Intel iMac that should be the equivalent of a 250MHz G4. That should run most of my old apps with little performance hit. Cool.
Hey, as long as it runs System 7, we’re good.
I guess this is more useful than installing OS X on a Timex computer circa 1981. But not by much.
Give it up people, buy new freakin software.
It DOES NOT work [yet]… the article is misleading. I tried it two days ago on my iMac Core Duo (10.4.4) as well as a DTK (10.4.3), and it fails to launch.
“Performance with the current CPU emulator using basic just-in-time (JIT) translation techniques is roughly 1/8-th of native speeds.”
Ugh. If you can accept that kind of performance, wouldn’t it be better to just keep and use your current PowerPC Mac? Or maybe pick up a used iMac? Since you’ll need the ROM image anyway…
That name should get attention in China, Australia, and New Zealand!
For anyone stuck with Outlook:mac 2001, this might help.
“I guess this is more useful than installing OS X on a Timex computer circa 1981.”
Didn’t those computers use cassette tapes for memory? Or was it 8 Track? Wax cylinders? LOL
Just don’t choose Swiss cheese software to go with your Darwine.
Oops. Sorry. Wrong thread. Too much Darwine too early in the day. <hic>
to jfbiii:
As much as I’d like to believe it’s just as easy as buying new software, the software I need for my field is a standard and does not exist on any other platform besides classic and it is still widely used in my field (systematics).
So buying new software is not an option until a new version is written and this is difficult as the writers have full time faculty jobs and do this on the side.
Sheepshaver.
I don’t get it.
Ampar,
It was the Timex Sinclair that originally sold for $100, and I believe it was 1982. I almost got one to practice BASIC with.
I just checked. You can get a nice 266 MHz beige G3 off ebay for under $50 (plus shipping). I have a warehouse full of older Mac (built by Sony) 640×480 monitors (they’re still good and I never thro anything away). If anyone wants one let me know, I can drop it off at the UPS store. You pay to pack and ship and the monitor is Free.
It seems to me that just getting some older Mac hardware to run your classic apps native would be simpler and easier than taking a chance on contaminating your current OS-X machine.
DRAM and parts for older Macs is dirt cheap also. I have several older machines that are stuffed out. I should also say I never use them anymore because OS-X rocks but the old hardware is too cool to throw away.
Gee, maybe with Classic going away, this old hardware will be worth something after all

Quick question here. I’ve tried to set this up on my iMac G5 1.9, but the only way I can get an OS9 desktop up without screen corruption is by holding down Shift whilst it loads to turn off all the extensions. The corruption takes the form of the screen stretching horizontally, and whilst the background draws okay, all the icons, windows & menus are all over the show.
If I use Extensions Manager and disable all extensions, then restart OS9, I still get the corruption, so I don’t think it’s a particular extension causing the problem.
I’m using the Mac OS ROM from the Apple Rom Update 1.1 available on their Website, which I extracted using Tomeviewer. My MacOS 8.6 install disk also causes the corruption, so it’s nothing in OS9.
Any ideas? Is it something simple, or contact the developer time?
common people. buy new freaking software.
yeah. what he said…
To all the “Buy new software already” people…
Sometimes industry-specific software is only available on Mac Classic or on Windows, or whatever, and must be used. This is not a difficult concept. It really isn’t. Please put some effort into not being ignorant.
It might be fun to load and run a bunch of my old System 7 vintage software. Yeah, i keep disk images of most of it on Magneto Optical disks.
While it might be fun to do, I can’t see doing it for long.
Oh, but I gave my old PowerMac 8500 to a friend who doesn’t need it any more… maybe I could just take it back, load ‘er up… just to give myself a reality check and be GLAD I’m running OS X!
Fixed it. Woo-hoo. Works great.
Now, if only I can find a use for it…..where’s my copy of Master of Orion 2?
Dave H, How did you manage to get around the problem? If you happen to look at this please let me know, it would be much appreciated, Ive been looking for a solution for a while. Every time I boot into classic mac with sheepshaver on my intel Mac, the screen becomes corrupted, streched and such.
here’s to all the people that have commented “buy new software,” or related comments…
sometimes programs that are still useful are no longer supported or have been discontinued (such as Adobe Live Motion, a wanna-be flash annimation program). the last version (2.0) was powerPC native but won’t run on the intel macs via rosetta. i learned how to use LM 2.0 pretty quickly and the interface is MUCH better than flash. at work i have to use flash (on an intel based mac) every now & again to make web ads……..i would MUCH rather be using Live Motion 2.0 since i already know how to use it well..
so dudes…. GET OFF. sometimes you CAN’T buy a new piece of software.
I would like to propose not to hold back until you get enough money to order goods! You can take the personal loans or just collateral loan and feel fine
