Solution 1Recommended

Verify Transferability and Upgrade to a Supported Office Version

Determine if your Office 2016 license is transferable and learn how to activate a newer, supported version on your new Mac.

In most cases, a standard Office 2016 for Mac license is tied to the original device and is generally not transferable to a new Mac. Additionally, Office 2016 has reached its end of support, meaning it no longer receives critical security updates or compatibility patches for newer macOS versions.

To ensure seamless performance on your new MacBook, it is highly recommended to purchase a modern edition like Microsoft 365 or Office 2021 instead of trying to migrate unsupported software.

1
Check your current license status

Log into your Microsoft account at account.microsoft.com/services to check if your Office 2016 license allows for installation on a new device.

2
Purchase a new license

If your license is non-transferable, purchase a newer version such as Microsoft 365 or Office 2021. Avoid purchasing Office 2019, as it has a much shorter remaining support lifecycle.

3
Redeem the new product key

Navigate to redeem.microsoft.com, sign in with your Microsoft account, and carefully enter the 25-character product key to bind the new license to your account.

4
Install Office on the new Mac

Download the installer from your Microsoft account services page and follow the on-screen prompts to install Word, Excel, and other apps on your new MacBook.

Can I deactivate Office 2016 on my old Mac to use it on the new one?

Will Office 2016 work on macOS Sonoma or newer?

Office 2016 for Mac is 32-bit/64-bit software that is not officially supported on recent macOS versions like macOS Monterey, Ventura, or Sonoma. Even if you manage to install it, you will likely experience frequent crashes and compatibility issues.
