I bought a MacBook Air recently and wanted OctaChainer on it. So I just uploaded a native OS X version here:
As a brand new Mac owner I’m not familiar with how to deploy software on OS X, so I might have gotten something wrong.
It runs fine on my El Capitan mac, and I’ve checked that the .wav and .ot are the same as on the Windows version. So it should be perfectly safe. But as always, own risk, etc.
