EndNote X8 Keeps Crashing on Mac

I would just like to add my frustration here. I am using Endnote X8 because my academic supervisor and team use it and we want to share libraries to enable academic collaboration. But I have to say that since I installed it on my Mac running OSX Sierrra, it continually freezes on me whenever I try and open a new reference. This is completely unacceptable, and I am dismayed and shocked to read such continual feedback in these forums from two years ago with seemingly no improvement in stability! Are you hearing us at all? How can the most widely used professional academic reference software, actively promoted by the university, not work on both platforms? Now I can’t even access my library to transfer it!!

Can anyone else give some advice here, or let me know how to transfer my library to another more Mac-friendly service? 

Thanks!
