Fix Microsoft Office 2024 Apps Crashing on MacBook Air
Question details
Microsoft Office Home & Business 2024 applications (Word, Excel, PowerPoint, Outlook) crash immediately after being installed and launched on a MacBook Air.
- Product
- Microsoft Office 2024
- Device & OS
- macOS
- Scenario
- Launching Office apps immediately after installation or entering a product key.
- Observed behavior
- The applications crash instantly on startup, which may be caused by corrupted preference cache files, damaged licensing tokens, or issues with third-party access codes.
Ensure your macOS is fully updated to the latest version and completely close any running Microsoft applications or the AutoUpdate tool before proceeding.
Reset Office Container and Preference Data
Corrupted cache and preference files from previous installations are the most common cause of immediate crashes on launch.
macOS isolates app data in specific container folders. When you install a new Office version like 2024, outdated or corrupted cache files can cause fatal startup conflicts.
Open Finder, press Command + Shift + G on your keyboard, type ~/Library/Containers/, and press Enter.
Locate the folders named com.microsoft.Word, com.microsoft.Excel, com.microsoft.Powerpoint, and com.microsoft.Outlook. Drag these folders to your Desktop to back them up.
Press Command + Shift + G again and navigate to ~/Library/Group Containers/. Find the folder named UBF8T346G9.Office and move it to your Desktop.
Restart your MacBook Air and launch Microsoft Word to see if the crash is resolved.
Use the Microsoft License Removal Tool
Clear conflicting or corrupted license tokens that prevent Office from verifying your subscription.
Verify License and Reinstall Office
If you used a third-party key or your installation is corrupted, verify your account status and perform a clean installation.
Try WPS Office for a Lightweight, Crash-Free Mac Experience
If Microsoft Office 2024 continues to crash on your MacBook Air or if you are dealing with invalid third-party keys, consider switching to WPS Office. It provides a stable, unified workspace that operates smoothly on macOS without heavy resource usage.
- 1. Download WPS Office for Mac: Visit the official WPS website and download the macOS installation package.
- 2. Install the Application: Open the downloaded file and drag the WPS Office icon into your Applications folder.
- 3. Open Your Files Seamlessly: Launch WPS Office and directly open your existing .docx, .xlsx, and .pptx files with zero formatting loss.
Frequently Asked Questions
Why does Office 2024 crash immediately upon opening on macOS?
Immediate crashes are typically caused by corrupted container preferences, an outdated macOS version, or conflicts with pre-existing Microsoft license tokens on your device.
Will I lose my Word documents if I delete the com.microsoft.Word folder?
No. The container folders only store application preferences, templates, and temporary cache. Your saved documents are stored safely elsewhere on your hard drive and will remain unaffected.
What should I do if my Office 2024 product key says it is already redeemed?
If you bought the key from an unauthorized third-party marketplace, it may have been revoked, resold, or region-restricted. You will need to request a refund from the seller and purchase a legitimate license from an authorized retailer.
How do I know if my Office 2024 license is properly linked to my account?
Log in to the official Microsoft website with your account credentials and navigate to the 'Services & subscriptions' page. If your Office 2024 purchase is valid and linked, it will be listed there.
