Hi, I am working on a Mac as main machine. I use the native Emacs package for MacOS, but other than that just a standard Emacs installation with my ~/.emacs.d containing all configurations, packages etc.
I also work on linux and on windows, and I had no trouble just porting my ~/.emacs.d over to those platforms and also have everything working, so I expect you will be fine 
Thanks for sharing your Emacs configuration, I will try to have a look at some point.
Cheers,
Marc
