Are there any difference if I try it for Mac?

Welcome to the forums,

I doubt there are any issues on a Mac - the Cubecart guys code on Macs....

The only differences may be minimal browser standards compatibility issues.

It's a system that's based on a web-platform, so whatever computer you use, so long as it has an internet browser, should really work.

If you're talking about hosting your own system using your own Apple computer, then that's a different story.
