We do not produce a version of our software for Apple Mac or iPad.
For those with the required technical expertise it is possible to use "Crossover" (www.codeweavers.com/products/) - i.e. Mac software with no actual Windows installed at all.
There is also a third party application "Parallels" available at www.parallels.com/uk/. This is a "PC emulator" and we understand that it is much more expensive, and requires the additional purchase of a Windows license.
A user of Parallels solved a problem with running PC-Rail using 'Procedure 2' in the documentation.
