extlist = mexext('all');

The mex command identifies a platform by its arch value, which is the output of the computer('arch') command. For Mac platforms, the value is maci64.

Search the arch field in extlist for 'maci64', and display the corresponding ext field. 

for k=1:length(extlist)
   if strcmp(extlist(k).arch, 'maci64')
   disp(sprintf('Arch: %s  File Extension: %s', extlist(k).arch, extlist(k).ext))
   end
end
Arch: maci64  File Extension: mexmaci64
