There are a variety of good ways to access Sharepoint document libraries from your mac. Some, such as plain access via the web, don’t offer much in the way of native integration. While others provide a full native filesystem interface that lets you access Sharepoint as a mapped drive.
Sharepoint via the Web
The easiest starting point is simply accessing Sharepoint via the web through the Office 365 portal. In order to get the richest experience via the web you’ll want to make sure you have a modern version of your browser. Microsoft keeps this list of supported browsers.
Mapping a Drive via WebDAV
While mounting Sharepoint as a network Drive using WebDAV mostly works in a Windows environment, it doesn’t function correctly on Mac when connecting to Office 365.
Microsoft Document Connection
In versions of Office previous to 2016 Microsoft included an app called Document Connection to move data in and out of Sharepoint, but it has been since discontinued in favor of more direct integration inside the office 365 apps.
Mapping a Network Drive
Third-party tools like ExpanDrive integrate directly with the Sharepoint API building in native access to any Mac. A user authenticates one time using the same login flow a they access Office 365 via the web, including MFA and SAML configurations. They can then access their entire Sharepoint setup as a fast, aggressively cached network drive that provides advanced features like smart-sync offline mode, integrated link sharing, and more.
OneDrive sync client
Another option is to use the OneDrive sync client to access Sharepoint on your mac. It provides reasonable integration and speed and is available from Microsoft. However, it doesn’t make managing a configuration with fine grained permissions and many different sites particularly. easy.
