Our program is not set up to work on an apple operating system. Several customer however do have macs and useing software like bootcamp or parallels to allow a windows based program to work on the mac/apple computer. The remote access from one computer to another over the internet may not work when using an apple operating system. If you want to use the computer for managing your rentals I would recommend a windows based system.
Boot Camp is software included with OS X so you can run compatible versions of Microsoft Windows on an Intel-based Mac.
