OS X Lion was the first version to use an x64 kernel, and there were definitely x86 (32-bit) versions of the OS and apps. In particular, the quicktime runtime / codecs (until quicktime x) was only x86, and various VFX apps on OS X had to write RPC code to communicate with it as a 32-bit process from 64-bit land. |
