Hello @tnuis ,
Welcome to the Poly Community.
The Polycom CX100 Speakerphone was originally designed specifically for use with Microsoft Office Communicator 2007. Later versions of Lync and then Skype for Business Client added support via the clients.
The CX100 is end of sale and end of support and personal knowledge there was never a specific driver for Mac.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
