Solution 1Recommended

Use Microsoft 365 for Office on both macOS and Windows

Choose a qualifying Microsoft 365 subscription when you need desktop Office apps in both operating systems.

Installing Office on macOS does not prevent you from using Windows through Boot Camp. Each operating system needs its own Office installation, but a qualifying Microsoft 365 subscription can cover both, subject to the plan's user and device limits.

1
Check the subscription's desktop app entitlement

Open your Microsoft account's Services & subscriptions page and select your Microsoft 365 subscription. Confirm that it includes desktop Word, Excel, and PowerPoint for both Mac and Windows; web-only plans do not provide these installations.

2
Install Office in macOS

Start your Mac in macOS, sign in to the Microsoft account associated with your subscription, and use the Install apps or Install Office option. Run the Mac installer, then open Word and sign in to activate it.

3
Install Office in Windows

Restart into your existing Boot Camp Windows installation. Open Microsoft's Office installation page, sign in with the licensed account, download the Windows installer, and run it.

4
Verify activation in both environments

Open Word in each operating system and sign in with the account assigned to the subscription. If you receive a device or sign-in limit message, review the subscription's device management options and plan limits.

Use Microsoft 365 for Office on both macOS and Windows
Windows needs its own license: A Microsoft 365 subscription licenses Office apps, not the Windows operating system. Boot Camp does not supply a Windows license.

Frequently Asked Questions

Will installing Office on macOS stop me from using Windows through Boot Camp?

No. macOS and Boot Camp Windows are separate environments. Install Mac Office while running macOS and Windows Office while running Windows; each installation must have valid activation rights.

Can one Office Home and Student 2019 license cover both environments on the same Mac?

Generally, no. Office Home and Student 2019 is licensed for one PC or Mac. Check the purchase terms through your Microsoft account's Services & subscriptions page, and do not assume the shared physical hardware permits two Office installations under one license.

Should I buy the Mac or Windows version of Office?

For a one-time purchase, choose a license and installer that cover the operating system where you will use Office. If you need desktop apps in both macOS and Windows, a qualifying Microsoft 365 subscription is usually the simpler option; otherwise, check whether separate licenses are required.

Does every Microsoft 365 plan include desktop Office for Mac and Windows?

No. Some plans provide web apps only. Before purchasing, open the plan's feature list and confirm it includes desktop Word, Excel, and PowerPoint for both platforms, then review its user and device limits.

Does Microsoft 365 include a Windows license for Boot Camp?

No. Microsoft 365 app licensing and Windows licensing are separate. In Boot Camp Windows, open Settings and search for Activation to check the Windows activation status.
