Moving custom output styles between X7 Mac and PC

Hi, Im struggling with moving a custom output style bteween computers. I created a new style for my thesis on the desktop Mac version of endnote X7, hoping to easily use it on the work PC I am formatting my PhD thesis on. 

I (wrongly) assumed that syncing with online would enable me to do this, however from what I can gather custom output syles dont sync with endnote online. 

Whats the most straight forward way to do this… with only a few weeks until I submit I really want to avoid wasting any time duplicating work?

Any help is hugely appreciated :slight_smile:

Thanks very much for the detailed and prompt response, great advice :slight_smile:
