SheepShaver should boot all MacOS versions from 7.5.2, to 8.6. However,
your mileage may vary. If it doesn't boot, try again with extensions disabled
(by pressing the shift key) and then remove some of these extensions:"A/Rose",
"MacOS Licensing Extension", "Speed Doubler", "68k FPU extensions" and "MacsBug".
The colors are wrong in 16 or 32 bit graphics modes
If you're running SheepShaver on something other than a PowerMac, it may be
that 16 or 32 bit graphics modes show false colors due to the frame buffer being
little-endian. Apart from patching the X server, there's unfortunately nothing
that you or SheepShaver can do about this.
Full-screen mode doesn't work
Some X servers on Linux PPC don't support DGA and full-screen mode cannot be used
with these (in this case, you should disable it in the "Graphics" settings). If you
are seeing a message like "cannot map /dev/kmem (permission denied)", you have to
either run SheepShaver as root (not recommended) or give yourself appropriate access
rights to /dev/kmem if you can login as root.
Ethernet doesn't work
You have to either install the sheep_net driver or configure the ethertap device in the Linux kernel to use Ethernet. See Using SheepShaver for more information.
If you're using TCP/IP on the MacOS side, you have to set up different IP addresses for Linux and for the MacOS.
SheepShaver crashes, but yesterday it worked
Try the "Zap PRAM File" item in the main menu of the SheepShaver preferences editor.
When you are using a ROM file and switch to a different ROM version, you have
to zap the PRAM file or SheepShaver might behave very weird.
Known incompatibilities
MacOS programs or drivers which access Mac hardware directly are not supported by SheepShaver.
Speed Doubler, RAM Doubler, 68k FPU emulators and similar programs don't run under SheepShaver.
MacsBug is not compatible with SheepShaver.
Known bugs
The QuickTime 2.5 Cinepak codec crashes the emulator.
Programs that use InputSprockets crash the emulator when in window mode.
Help and Support:
SheepShaver is heavily under construction at the moment, and there is no
real user-level support yet.
