The only commercial tool I know of for this is T3D (formerly Slicer)
from Fortner Research:

If you have MATLAB for the Mac, you can also use Chuck Denham's MexCDF,
a MATLAB/NetCDF Interface for which Mac binaries are available at

There is some limited Mac support for FERRET:

GrADS is also implemented on Macs, and the latest version is supposed to
have some support for reading netCDF files with some restrictions, but I
don't know any more details:

We're currently working on a Java browser for netCDF files that runs on
the Mac as well as any other Java platform.  I've used it to look at
netCDF files on the Mac, but it's not ready for release yet.  Maybe in a
month or two ...
