This is a list of Classic Mac OS Macintosh software that no longer run on current Macs. The software might require versions of Classic Mac OS. Most old programs can still be run using emulators, such as SheepShaver, vMac, or Basilisk II.
For a list of macOS programs, see List of Mac software. Third-party databases include VersionTracker, MacUpdate and iUseThis. Since a list like this might grow too big and become unmanageable, this list is confined to programs for which a Wikipedia article exists.
