    Microsoft 365 is still compatible with supported versions of macOS on MacBook Air. The crash report shows Excel is terminating at launch with a dynamic linker (DYLD) “Symbol missing” error in the CocoaUI framework, which indicates a corrupted or mismatched Office installation rather than a general incompatibility.

    Use the following supported remediation steps for Office apps on Mac that quit unexpectedly:

    1. Completely quit all Office apps
      • On the Apple menu, select Force Quit.
      • In Force Quit Applications, select each Office app (Excel, Word, PowerPoint, Outlook, OneNote) and choose Force Quit.
      • Repeat until all active Office apps are closed.
    2. Remove Office app data and preferences
      • In Finder, open Applications and move all Microsoft 365 for Mac apps to the Trash.
      • In Finder, on the Go menu, select Go to Folder… and go to:
        • ~/Library/Containers/
          • Delete folders starting with:
            • com.microsoft.Word
            • com.microsoft.Excel
            • com.microsoft.Powerpoint
            • com.microsoft.Outlook
            • com.microsoft.OneNote
        • Go back to ~/Library/ and open Group Containers.
          • Move these (if present) to the Trash:
            • UBF8T346G9.ms
            • UBF8T346G9.Office
      • This clears corrupted app containers and shared Office data that can cause immediate crashes.
    3. Reset Office preferences (Excel-specific)
      • In Finder, on the Go menu, open the hidden Library folder (hold OPTION while opening Go → Library).
      • Open Group Containers.
      • Open the folder whose name ends with .Office.
      • Locate and delete Com.microsoft.officeprefs.plist.
      • If Excel still crashes after reinstall (see next step), delete the entire .Office folder in Group Containers to reset all Office preferences back to first-run state.
    4. Reinstall Microsoft 365 for Mac
      • After removing apps and data as above, reinstall Microsoft 365 for Mac from the Microsoft account portal as described in the moderator guidance.
      • Launch Excel again and confirm whether it opens without crashing.
    5. If crashes persist, perform a clean startup of macOS
    6. If still failing, fully remove and reinstall Office
      • Use the full removal guidance for Office for Mac (for the relevant version) and then reinstall, as described in the Office for Mac troubleshooting articles in the context.

    These steps target corrupted preferences, containers, and shared frameworks that commonly cause “quit unexpectedly” or immediate crash-on-launch behavior for Excel and other Office apps on Mac.
