  • SheepShaver is being maintained!
    Note especially:
    "Installation and setup:
    If you have an existing SheepShaver setup, you can simply replace the application with the new application."
    This means you can use the disk image available here, copy the new application over the existing one and you're good to go.

  • More polished standalone disk image with simple install of preferences since all support files are on the disk image. -- DickFurnas - 21 Feb 2008
  • Networking seems to be unstable, causing SheepShaver to either silently quit or lock up requiring a force quit. -- DickFurnas - 21 Jan 2008
  • The disk image file contains material copyright Apple Inc. -- DickFurnas - 21 Jan 2008
