I wonder if it actually needs OS9, PPC supported started (barely) in the System 7.1 era

• EL_Loco 5y ago
  Yes, but lots of software made for PPC began requiring OS8, then 8.6, and then a bunch required OS 9 to run.

    How far back did Carbon support go?
    • greenknight 5y ago
      native mac os 8 and 9 applications could only be run under rosetta. they could be rebuilt to run under cocoa.
      • mattl 5y ago
        They required some Carbonization. Also then would run under Classic or Carbon. Rosetta was for Cocoa I think.

          Rosetta was a PowerPC CPU emulator that allowed running any kind of PowerPC OS X application on Intel Macs. Carbon was a set of largely OS 9 compatible APIs that allowed an easy transition for apps that could be recompiled. Classic was a virtualized OS 9 environment available on OS X (up to 10.4 Tiger, PPC Mac only) that allowed running unmodified binaries for pre-OS X Macs. Most things that didn't require special hardware access or precise timing ran fine, but things like real-time audio and MIDI applications did not.

        Not Rosetta, Classic

      It's not that easy. Carbon is largely a subset of the classic MacOS toolkit APIs reimplemented in MacOS X to provide a migration path for existing application to MacOS X. IIRC carbonized applications commonly targeted version going back to MacOS 8.6 - 10.x with a single executable. From my unreliable childhood memories the next common range started at MacOS 9.0 (or 9.1).
