Like in Windows, you can open the hosted versions of Word, Excel, Powerpoint and other O365 applications from a MacOS web browser. You'll have the same features and functionality on the Mac as you would from a Windows computer.
There is a Microsoft Teams application for MacOS which works very well. Other O365 applications like Delve and Stream are available from office.com, but they are not part of this project, not even Teams. Moving data from iSpace and into SharePoint/OneDrive is our sole focus.
Check the 'Quick Start Guides/Resources' listing found throughout this site for links to information on these other applications.
