An ABI covers a lot of ground, generally including the entire OS interface.
Hence Apple's System 7 for Power Macintosh certainly has a unique API.
However, it uses the same calling convention as AIX. It also supports XCOFF
in addition to Apple's own PowerPC Executable Format (PEF). (And PEF
basically encodes the same runtime linking information as XCOFF only in a
much more efficient way.) In other words, things are enough the same that a
lot of development tools should be applicable between the two systems. (At
least if you're willing to cross-host the tools.)
