Fix Excel for Mac Hanging at Startup on Apple Silicon M1
Question details
The user needs to resolve an issue where Excel for Mac freezes and becomes unresponsive during launch on an Apple Silicon processor.

- Product
- Microsoft Excel for Mac
- Device & OS
- Apple M1 Mac / macOS Sonoma
- Scenario
- Opening the Excel application.
- Observed behavior
- The application becomes unresponsive (hangs) during startup, often requiring multiple force-quits before it successfully opens.
Before troubleshooting, ensure all other applications are closed and your work is saved. Verify whether the freezing happens when opening a specific workbook or when launching the blank Excel application itself.
Isolate the Issue (Workbook vs. App Launch)
Determine if a specific file is causing the hang or if the application itself is corrupted.
Sometimes Excel hangs because it is trying to recover or open a corrupted file on startup. Isolating the launch behavior helps pinpoint the root cause.
Open Excel directly from the Mac Launchpad or Applications folder without clicking any specific spreadsheet file.
If Excel opens successfully, go to File > Open and select the workbook you were trying to access. If it hangs now, that specific file may be corrupted.
If the application becomes unresponsive, press Command + Option + Esc, select Microsoft Excel, and click Force Quit.
Remove Excel Preferences and Cache
Clearing corrupted configuration files can often resolve persistent startup hangs on macOS.

Frequently Asked Questions
Why does Excel freeze on macOS Sonoma?
Freezes on macOS Sonoma can be caused by outdated Excel versions, incompatible third-party add-ins, corrupted preference files, or compatibility hiccups during the Rosetta to native Apple Silicon transition.
What is the difference between an Excel crash and an Excel hang?
A crash occurs when Excel unexpectedly closes completely and generates a standard crash report. A hang (or freeze) means the app remains visually open but stops responding to any clicks or inputs, requiring a force-quit.
How do I completely force quit a stuck Excel window on a Mac?
Press the keyboard shortcut Command + Option + Esc to open the Force Quit Applications window, select Microsoft Excel from the list, and click the 'Force Quit' button.
