OverTone analyzer for MAC? Any free links?

[PaigeMtl]

Hi,
I just switched over to using a mac and can't find a decent (free) software similar to the OverTone Analyzer for Windows. Does any one have any suggestions?

fyi. I cannot use my old windows based pc because it officially gave it's last blue screen of death. May it r.i.p.
It was good to me during the past few years.

You could get one of the free/cheap windows emulators on your mac and then keep using your winxx software.

Thank you.

@RANETH: Have you used this software before? If my research is correct it only reads imported files (so no real time). The comments seem to be that it is not user friendly. Do you agree with that?

@PADMA: I found WinOnX as an emulator through the AppStore for 5$ There is no guarantee that OverTone won't crash, but I guess for 5$ I'll have to cross my fingers.
