MAC contest logging software
Honestly? N1MM running in a Windows VM. There are some decent paid options like MacLoggerDX.

Be careful. I've found free software to be be worth every penny! After messing with a number of free ham software packages for the MAC I decided to run a MS Windows machine with N3FJP logging software. I've found Windows to be more user friendly with fldigi and Signalink also.
I am a MAC user and use MAC for everything else since retiring. But for the shack I found much better user groups for Windows software. It's just a fact of life which was true of Engineering apps when I was working. Like I said...when I retired I jettisoned MS. If it were not for getting back into ham radio I would not own a Windows machine.
