Question details
The user needs to activate a Microsoft Office 2019 license on a newly purchased MacBook Pro, which involves transferring the license from a previous Mac device.
- Product
- Microsoft Office 2019 for Mac
- Device & OS
- macOS
- Scenario
- Moving an existing Office 2019 installation to a new Mac or setting up a newly purchased Office 2019 lifetime license on a MacBook Pro.
- Observed behavior
- Requires associating the product license with a Microsoft account and potentially deactivating the previous installation to successfully complete the activation.
Ensure you have the login credentials for the Microsoft account associated with your Office 2019 purchase and a stable internet connection before beginning the activation process.
Deactivate Old Device and Reinstall via Microsoft Account
Use this method if you have a lifetime license of Office 2019 tied to your Microsoft account and need to transfer it to your new MacBook Pro.
Office 2019 licenses are typically valid for a single device. To move your installation, you must first unlink the license from your old Mac before activating it on the new one.
Open a web browser and go to https://office.com/myaccount. Sign in using the exact Microsoft account linked to your Office 2019 license.
Navigate to the 'Installs' or 'Devices' section, locate your previous Mac, and select the option to 'Sign out of Office' or 'Deactivate' the old device.
From the same account dashboard, click the 'Install' button to download the Office 2019 installer package for your new MacBook Pro.
Run the downloaded installer on your new MacBook Pro. Once installed, open any Office app (like Word) and sign in with your Microsoft account to complete the activation.
Activate Using a Third-Party Product Key
Follow these steps if you purchased Office 2019 from a third-party retailer and received a 25-character product key rather than an immediate digital account link.
Use Telephone Activation via Microsoft Support
If online activation fails or you receive a 'maximum activations reached' error despite deactivating the old device, you must use telephone activation.
Try WPS Office: A Free and Lightweight Alternative for Mac
If you are struggling with Office 2019 activation limits or prefer not to deal with complex license transfers, WPS Office is an excellent free alternative. It provides a full suite of productivity tools that run seamlessly on your new MacBook Pro without strict single-device limitations.
- 1. Download the Mac Installer: Visit the official WPS Office website and download the setup file specifically designed for macOS.

- 3. Start Creating: Launch WPS Office from Launchpad and instantly open, edit, or create your documents without worrying about activation codes.

Frequently Asked Questions
Can I use my Office 2019 license on both my old Mac and new MacBook Pro simultaneously?
No. A standard Office 2019 license is valid for a single Mac only. To use it on your new MacBook Pro, you must deactivate it from your old Mac first through your Microsoft account.
How do I find my Office 2019 product key if I lost it?
If your license is already tied to your Microsoft account, you do not need the original product key; simply sign in at office.com/myaccount to reinstall. If you haven't linked it yet, you will need to check the retailer's email receipt or the original physical packaging.
What should I do if my Mac displays an 'Activation limit reached' error?
This error means the Microsoft servers still detect your license as active on another device. Sign in to your Microsoft account to ensure the previous device is deactivated. If the error persists, you will need to contact Microsoft Support for telephone activation.
