Although a post for quite some time ago, for completeness I'll add that RootsMagic (has both a free and pay for more advanced version) and the free FamilyTreeBuilder from MyHeritage (which can optionally be synchronized with a MyHeritage tree) both run on a Mac without having to set up a virtual windows machine.
Both take care of the Windows side of things seamlessly for you.
Do take care however, until the expected updates are available, not to try either under the MacOS upgrade to Catalina currently available, Nov 2019.
RootsMagic has a nice interface to work with FamilySearch for research hints, and their FamilySearch tree if you are a fan of collaborative trees (yes I know that can be a contentious subject, it is a completely optional feature).
RM also has a good hint system with Ancestry, FindMyPast and MyHeritage records which can be helpful for research.
