Upgrade to a Modern 64-bit Version of Microsoft Office

Since macOS Catalina and newer operating systems no longer support 32-bit apps, upgrading to a newer 64-bit Office release is the standard resolution.

Microsoft Office 2011 is a 32-bit application, which makes it fundamentally incompatible with macOS Catalina, Big Sur, Monterey, and all subsequent Apple releases. To continue using Microsoft products on these systems, an upgrade is required.

1
Choose a newer Office version

Decide between purchasing a one-time license like Microsoft Office 2021 or subscribing to Microsoft 365.

2
Download and install

Download the installation package from your Microsoft account dashboard and run the installer on your new Mac.

3
Sign in to activate

Open Word or Excel and sign in with the Microsoft account associated with your new purchase to activate the suite.

Frequently Asked Questions

Why exactly did Office 2011 stop working on my new Mac?

Apple removed support for all 32-bit applications starting with macOS Catalina (10.15). Because Microsoft Office 2011 was only ever developed as a 32-bit application, the Mac operating system can no longer execute its code.

Can I download a 64-bit update for Office 2011?

No. Microsoft never released a 64-bit version of Office 2011. You must transition to a newer release like Office 2019, Office 2021, or Microsoft 365, which are built on 64-bit architecture.

Is it still possible to activate my Office 2011 license on an older Mac?

Yes, the one-time purchase license can generally be transferred to another Mac running macOS Mojave or earlier. However, because the product is retired, you will likely need to use the telephone activation method provided in the setup wizard.
