Mac OS 7

1997 Mac OS 7.7a2c5 (emulated in SheepShaver)

Mac OS 7.7 encompassed pre-release versions of the successor to Mac OS 7.6.1 that were renamed to Mac OS 8 (code named "Tempo").

Features[]

Some of the features from the cancelled Copland project, such as the Platinum appearance and multithreading in the Finder, were salvaged into Mac OS 7.7, giving it a different look and feel than previous versions.[1]

History[]

Apple Computer initially planned the update as version 7.7. However, it was renumbered to "8" on March 8, 1997 to exploit a legal loophole and accomplish Steve Jobs's goal of terminating third-party manufacturers' licenses to System 7, effectively shutting down the Macintosh clone market.[2][3]

Known pre-release builds[]

  • Mac OS 7.7 (d3), still identified as "Mac OS 7.6" with a partial implementation of the Platinum appearance.
  • Mac OS 7.7 (d4), codenamed "Spinal" with a more complete Platinum implementation.
  • Mac OS 7.7 (a2c5), codenamed "Speedy" with incomplete 68K support.
  • Mac OS 7.7 (a3c1), codenamed "StrikesBack".[4]
NOTE: Subsequent alpha builds, starting with a4, were identified as "Mac OS 8".
