Since there are many OSes these days the need to let them communicate with each other is higher than ever. Because we have experience on all major OSes our knowledge can be useful if you need help in a environment that has more than one type of OS.
In fact we are very agnostic about OSes. In our opinion they all serve their purpose (for better and worse) and can live peaceful together. The main challenge is to connect them to each other.
OSes we can operate and make communicate with each other:
- Mac OS X
- Microsoft Windows (mainly Windows 2000 till Windows 7 and every in between)
This goes for file sharing, virtualization, file systems, networking etc.
