Fix Microsoft Office Compatibility Issues on M1 MacBook Air
Question details
Older versions of Microsoft Office fail to launch on an Apple M1 MacBook Air, especially after migrating data using Time Machine.
- Product
- Microsoft Office for Mac
- Device & OS
- Apple M1 MacBook Air (macOS)
- Scenario
- Transferring old applications from a previous Mac to a new M1 MacBook Air via Time Machine and attempting to open legacy Microsoft Office apps.
- Observed behavior
- Older Office applications like Office 2008 are incompatible with the Apple Silicon architecture and will not run, generating compatibility errors or simply failing to open.
Verify the exact version of Microsoft Office you are trying to run. Keep your Microsoft account login details handy in case you need to download a supported installer.
Upgrade to a Supported Version of Microsoft Office
Since older versions are permanently incompatible with Apple Silicon, upgrading to an M1-supported release is required.
Microsoft only officially supports Microsoft 365 and the one-time purchase license for Office 2021 on Mac devices with Apple M1 chips.
Legacy software like Office 2008 or 2011 lacks the 64-bit architecture and ARM support required by modern macOS versions, meaning they cannot be fixed or emulated using Apple's Rosetta 2.
Open the Applications folder on your Mac, locate the older Microsoft Office applications (Word, Excel, PowerPoint), and drag them to the Trash. Empty the Trash to ensure no conflicting legacy files remain.
Go to the official Microsoft website and purchase either a Microsoft 365 subscription or a standalone Office 2021 for Mac license.
Log into your Microsoft account dashboard, navigate to the Services & Subscriptions tab, and download the latest Office installer for macOS. Run the installer package and follow the on-screen prompts to install the M1-compatible suite.
Use WPS Office as a Native, Free Alternative on Your M1 Mac
If you do not want to purchase an expensive new license or subscription for Microsoft 365 just to open your documents on an M1 Mac, WPS Office is the perfect solution. It offers native Apple Silicon support for fast performance, complete file compatibility, and a familiar interface—all for free.
- 1. Download WPS Office for Mac: Visit the official WPS website and download the Mac installer. It will automatically detect and optimize for your Apple Silicon processor.
- 2. Install the Software: Open the downloaded .dmg file and drag the WPS Office icon into your Applications folder.
- 3. Open Your Legacy Files: Launch WPS Office and directly open your older Microsoft Word, Excel, or PowerPoint files without any formatting loss or compatibility errors.
Frequently Asked Questions
Can I use Rosetta 2 to run Office 2008 or 2011 on my M1 Mac?
No. Apple's Rosetta 2 translation environment only supports translating 64-bit Intel applications. Since Office 2008 and Office 2011 are 32-bit applications, they are entirely unsupported on modern macOS versions and cannot be run on an M1 Mac.
Why did my Office apps stop working after using Time Machine?
Time Machine copies exactly what was on your old Mac. If you migrated from an older Intel-based Mac running legacy 32-bit software, those specific application files are simply incompatible with the 64-bit ARM architecture of the M1 chip in your new MacBook Air.
Does Office 2016 or Office 2019 work on an M1 MacBook Air?
Office 2019 works on M1 Macs through the Rosetta 2 emulator, though it is not natively optimized. Office 2016 reached its end of support in October 2020; while its 64-bit later builds might run via Rosetta 2, Microsoft does not support it, and users often experience stability issues.
