Breeders Assistant requires a computer with Windows 10, Windows 8, Windows 7 or Windows Vista. Please note that Windows XP and earlier versions are not supported. A minimum of 1Gb memory is recommended.
In practice, any PC with Windows that is less than 6 years old will almost certainly be sufficient to run Breeders Assistant. Obviously you also need a printer to print out your pedigrees - any page-oriented printer that works with Windows should be sufficient, such as a typical inkjet or laser printer.
You can also run Breeders Assistant but you must also have a Windows environment on your Mac that supports genuine Windows based software. E.g. the 3rd party product 'Parallels' for the Mac together with a valid version of Windows is known to support Breeders Assistant. 'Parallels' can be obtained from most Apple stores.
If you are looking for a native pedigree program for the Mac you should consider our PedPro product.
