This guide shows you how to install and activate Microsoft Office 2016 Home & Business on a Mac using your product key.
Step 1: Uninstall older Office versions
Before you begin, we recommend uninstalling any previous Office versions from your computer to avoid activation or installation issues.
Step 2: Activate and download Office
Click the button below to start the activation process:
Sign in with your Microsoft account (or create one if needed).
Enter your product key when prompted.
Follow the instructions to associate the license and download Office.
Step 3: Install Office
Once the download is complete:
Open the installation file.
Follow the instructions on screen to finish the setup.
Note: The installer may be labeled as Microsoft 365. This is normal — it’s a shared setup file. After installation and activation, you’ll have the correct Office 2016 Home & Business edition linked to your Microsoft account.
Step 4: Confirm activation
To verify that Office is activated:
Open Microsoft Word.
Click Word in the top menu bar (next to the Apple logo, at the top-left of the screen), then select About Word.
You should now see your license type and whether it's activated.
