Use Microsoft 365 Web Apps (No Installation Required)

This is the ideal solution if you do not want to install any Microsoft software or executable files locally on your Mac.

Microsoft 365 offers fully functional web-based versions of Word, Excel, PowerPoint, and other essential applications. These run directly in your web browser (such as Safari or Chrome) on macOS, meaning no local installation or Windows environment is required.

Log into the Microsoft 365 portal

Open Safari or your preferred web browser and navigate to Microsoft365.com. Sign in using the same Microsoft account you used to accept the invitation.

3
Launch the web apps

On the left-hand sidebar or the main dashboard, click the icon for Word, Excel, or PowerPoint to open the web-based version of the app and start creating or editing your documents immediately.

Frequently Asked Questions

Do I need Boot Camp or Parallels to run Microsoft Office on my Mac?

No, you do not need Windows emulators or partitions. You can either use the fully functional web versions through your Safari browser or download the native macOS versions of the apps provided by your Microsoft 365 subscription.

Can I use my existing Apple ID email to accept the Microsoft 365 invitation?

Yes, you can use your Mac or iCloud email address to create a free Microsoft Account. The sharing link must be tied to a Microsoft Account, but that account can be registered under any valid email address you currently own.

Are the web versions of Microsoft Word and Excel exactly the same as the desktop apps?

The web apps are highly capable and perfect for standard editing, formatting, and real-time collaboration. However, they may lack a few advanced desktop features, such as complex macros or heavy data modeling tools in Excel.

Will my files be stored locally if I use the Microsoft 365 web apps?

By default, files created in the web apps are saved to the cloud via OneDrive. However, you can choose to download a copy of the finished document directly to your Mac's hard drive at any time.
