Works with my MacBook Pro (15", late 2013) running Mac OS X 10.11.1 (El Capitan). I plugged it in and in System Preferences-->Printers and Scanners, I added it and kept the default name as "USB Modem." No drivers were needed. Apparently, all the fax software needed is already built into the Mac OS X.
A field to enter the station ID is available. There are also settings to automatically answer the phone to pick up faxes and send each received fax to a folder, printer, and/or e-mail address.
Faxes are sent by "printing" the document to "USB Modem." Phone numbers can either be entered in or automatically pulled from the system's Contacts. There is an option to use a very plain and simple cover page (works just fine for me). Under the "Printer Features" section, there is an option to select resolution. High seems to be 200 dpi and low is 150 dpi.
In System Preferences, there is also an option to share this "printer." I turned it on. From another MacBook Pro (13" Mid 2010) also running 10.11.1, in System Preferences, the shared fax modem could be added as a "printer." At this point, the second computer could send a fax the same as if the fax modem were directly connected to it.
I tested it with both the Plain Old Telephone Service (POTS) and Ooma (which needed a *99, dialed before the phone number).
Bottom line is this fax modem worked just fine with Mac OS X. It's inexpensive, plain looking, yet does the job with no hassle.
