MacOS with MyCloud EX2 Ultra


I am using Macbook Pro and we got in our office MyCloud EX2 Ultra. After update to OS5 I am little bit strugling. Is there any basic WD or 3rd party software to sync some specific folders with NAS? I dont want to packup my macbook every 24hrs or anything like that. Just sync folders, to have backup, acces for my colleagues, and remote acces from my iPhone.
