Fix Microsoft To Do Crashing After Update on Mac (M1/Big Sur)
Question details
The user needs to resolve an issue where the task management application continuously crashes upon launch following a software update.

- Product
- Microsoft To Do
- Device & OS
- macOS Big Sur (MacBook Air M1)
- Scenario
- Launching the application right after installing a recent app update.
- Observed behavior
- The application stops opening entirely and crashes immediately as soon as the user tries to run it.
Verify that your Mac is connected to the internet so you can download any necessary system updates or reinstall the application securely from the Mac App Store.
Restart Mac and Apply macOS Updates
A simple system restart alongside installing pending operating system updates can clear corrupted cache data and resolve compatibility glitches.
Software updates often leave behind temporary files that can interfere with normal app launches, especially on M1-based Macs running macOS Big Sur. Restarting forces the system to clear these files and load a fresh state.
Click the Apple menu in the top-left corner of your screen, select 'Restart', and wait for your MacBook Air to boot up completely.
Open System Preferences from the Apple menu, click on 'Software Update', and install any available updates for macOS Big Sur.
Open the Mac App Store and navigate to the Microsoft To Do page to confirm that the installed version officially supports macOS Big Sur and M1 architecture.

Reinstall Microsoft To Do from Official Sources
If the application files became corrupted during the update process, completely removing and reinstalling the app will restore it to a working condition.
Collect Logs and Contact Support
When standard troubleshooting fails, escalate the problem to official support by providing detailed crash reports and system information.

Frequently Asked Questions
Why do Mac applications frequently crash immediately after an update?
Post-update crashes are generally caused by leftover, outdated cache files, incompatible configurations from the previous version, or glitches in how the new software interacts with macOS background services.
Where can I manually find application crash reports on macOS?
You can find crash reports manually by opening the Console app, which is located in Applications > Utilities. From the left sidebar, navigate to 'Crash Reports' or 'Diagnostic Reports' to view detailed logs for your applications.
Does macOS Big Sur have specific compatibility issues with M1 processors?
macOS Big Sur was the first operating system designed for Apple Silicon (M1). While native applications run flawlessly, older Intel-based applications running through the Rosetta 2 translator may sometimes experience slower initial launches or unexpected crashes.
