Reinstall and Activate via Microsoft Account
The most reliable way to activate Office on a new Mac is to download the Mac-specific installer directly from your Microsoft account services page.
Office Home & Student 2019 can be installed on either a PC or a Mac, but requires the correct platform-specific installer. Since you are moving from Windows to macOS, you must download the Mac version directly from your Microsoft account.
Open a web browser on your new Mac and navigate to https://account.microsoft.com/services. Sign in using the Microsoft account associated with your Office purchase.
Scroll through your list of subscriptions and purchased products until you find the Office Home & Student 2019 license.
Click the 'Install' button next to the Office 2019 listing. Microsoft will automatically detect that you are on a Mac and provide the correct macOS installer file.
Run the downloaded installer and follow the on-screen prompts. Once installed, open any Office app (like Word) and sign in with your Microsoft account when prompted to finalize the activation.

Frequently Asked Questions
Can I use a Windows Office 2019 license on a Mac?
Yes, Office Home & Student 2019 can be installed on either a Windows PC or a Mac. However, you cannot use the Windows installation file (.exe). You must log into your Microsoft account on your Mac and download the macOS-specific installer.
Why does Office say my license is already in use?
Office Home & Student 2019 is limited to one device at a time. Because the license was previously active on your Windows laptop, Microsoft's activation servers still register it there. You may need to uninstall it from the old PC or contact Microsoft support to authorize the transfer to the new Mac.
Is Microsoft Office 2019 natively compatible with M4 Macs?
Office 2019 is capable of running on Macs with Apple Silicon (including the M4 chip), but it may run via Apple's Rosetta 2 translation layer depending on the exact build. It functions perfectly well, though newer versions like Microsoft 365 or Office 2021 are fully optimized for native Apple Silicon performance.
