Hi Nick, xTuple ERP is one of a very small number of ERP solutions that runs natively on Macs (as well as Windows and Linux on the desktop, and just about any modern tablet or phone in a mobile browser).  Have a look at www.xtuple.com. Cheers, Ned

xTuple and PostBooks are the same thing.  There is all kinds of information including documentation, videos, and of course the software, at www.xtuple.com.
