I double-checked the wiki page, http://hashcat.net/wiki/doku.php?id=mask_attack , says this:
Is that the page you looked at (or do we need to update/improve other wiki pages)?
The problem is that cpu hashcat currently does not support mask-files (hcmask)...
If you insist to get this feature also for cpu hashcat you could try opening a trac ticket, https://hashcat.net/trac/ , and see if it'll get accepted.
Another problem ofc is that you can't run oclHashcat on a MAC, therefore there are only some remaining options:
1. run the mask within a (shell) script - one mask at a time - several sequential calls of the .app
2. maybe you can use different hardware + win/linux with a recent GPU to run oclHashcat
