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.

1
Restart your Mac

Click the Apple menu in the top-left corner of your screen, select 'Restart', and wait for your MacBook Air to boot up completely.

2
Check for system updates

Open System Preferences from the Apple menu, click on 'Software Update', and install any available updates for macOS Big Sur.

3
Verify application compatibility

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.

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Post-update crashes are generally caused by leftover, outdated cache files, incompatible configurations from the previous version, or glitches in how the new software interacts with macOS background services.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.
