Solution 1Recommended

Verify License Compatibility and Download from Microsoft Account

Check if your product key is valid for macOS by linking it to your official Microsoft account.

Microsoft Office 2021 Professional Plus is specifically designed for Windows and is typically distributed via volume licensing. Standard Mac editions are usually branded as 'Home & Business' or 'Home & Student'.

If you purchased a Professional Plus key from a third-party discount site, it may not be compatible with macOS or might not grant access to an official Mac installer.

Visit the Office Setup Page

Open your web browser and navigate to the official setup.office.com website.

2
Sign In to Your Account

Click 'Sign In' and enter your Microsoft account credentials. If you do not have an account, you will need to create one.

3
Enter the Product Key

Type in your 25-character product key when prompted, select your region, and click 'Next'.

4
Check for Mac Download

If the key is valid and compatible with Mac, you will be redirected to your Services & Subscriptions page where you can click 'Install' to download the macOS package. If it states the key is for Windows only, you cannot use it on your Mac.

Verify License Compatibility and Download from Microsoft Account
Compatibility Warning: If your account only offers a Windows installer (.exe), your license is strictly for PC. You cannot run a Windows Office installer on macOS without using a virtual machine like Parallels.

Frequently Asked Questions

Can I install Office 2021 Professional Plus on a Mac?

Officially, Microsoft Office 2021 Professional Plus is a Windows-only edition. Mac users typically need Office 2021 Home & Business, Home & Student, or a Microsoft 365 subscription to install Office natively on macOS.

Why is setup.office.com rejecting my product key?

Product keys from unauthorized discount sites may be blocked by Microsoft. Additionally, the key might be for a different region, a volume license not meant for consumer resale, or strictly a Windows edition.

Is there a standalone installer for Office 2021 for Mac?

Yes, standalone Mac installers are available through your Microsoft Account under the 'Services & Subscriptions' section, provided you have a valid, Mac-compatible license linked to your account.

What should I do if I bought a Windows Office key for my Mac by mistake?

You will need to contact the retailer for a refund or exchange. Alternatively, you can run Windows on your Mac using Boot Camp or virtualization software like Parallels, or simply use a free alternative like WPS Office for Mac.
