Compare License Types and Reinstall Office on a New Mac
Both retail and digital versions offer identical features; the main difference is the delivery method. Reinstallation relies entirely on your Microsoft account.
A retail package includes a physical box with a printed product key, while a digital download ties the license directly to your email or Microsoft account upon online purchase. The applications (Word, Excel, PowerPoint) and features are exactly the same.
If you purchased a retail box, navigate to setup.office.com, sign in with your Microsoft account, and enter your 25-character product key to bind the license to your account.
Open a web browser on your new Mac and navigate to account.microsoft.com/services. Sign in with the account linked to your Office 2021 license.
Locate 'Office Home and Student 2021' in your list of purchased products and click the 'Install' button to download the installer package for macOS.
