Fix Microsoft To Do Mac App Not Signing In or Opening Settings
Question details
The user is unable to sign into the Microsoft To Do desktop application on Mac, and the Account, Settings, and Preferences menus are completely unresponsive.
- Product
- Microsoft To Do
- Device & OS
- macOS
- Scenario
- Attempting to log into the desktop application or access app settings after launching it on a Mac.
- Observed behavior
- The application opens without displaying a sign-in prompt. Clicking on Account, Settings, or Preferences yields no response, and a standard reinstallation of the app does not resolve the issue.
Before proceeding, verify that your Mac is connected to the internet and check if your macOS version is fully updated. You can temporarily manage your tasks by logging into the web version of Microsoft To Do via your browser.
Perform a Clean Reinstallation of Microsoft To Do
Completely removing the application along with its hidden cache files before reinstalling often resolves stubborn login bugs and unresponsiveness.
Simply moving an application to the Trash does not remove all of its configuration files. If the local cache is corrupted, the application may enter an unresponsive state where it cannot load the login window or settings menus.
Press Command + Option + Esc, select Microsoft To Do from the list, and click 'Force Quit' to ensure the app is fully closed.
Open Finder, navigate to your Applications folder, right-click on Microsoft To Do, and select 'Move to Trash'.
In Finder, click 'Go' in the top menu bar, select 'Go to Folder...', type '~/Library/Containers/' and press Enter. Locate any folders named 'Microsoft To Do' or 'com.microsoft.to-do-mac' and move them to the Trash.
Open the Mac App Store, search for Microsoft To Do, and click the cloud icon to download and install a fresh copy.
Launch the newly installed application and click on 'Account' to verify if the sign-in prompt successfully appears.

Frequently Asked Questions
Why is my Microsoft To Do app opening but not loading preferences on Mac?
This typically occurs due to corrupted application cache files or an OS compatibility issue, especially on older versions like macOS Catalina. Clearing the app's container files in your Mac's Library folder usually restores functionality.
Can I still use Microsoft To Do if the Mac app refuses to work?
Yes. You can access all your lists and manage tasks by logging into the Microsoft To Do web version using any browser like Safari or Chrome, which works entirely independent of the Mac app.
Will I lose my tasks if I delete and reinstall the Microsoft To Do app?
No, your tasks will not be lost. All Microsoft To Do data is synced to your Microsoft account in the cloud. Once you successfully reinstall the app and sign in, your data will automatically sync back.
How do I check my macOS version to see if it's compatible with the app?
Click the Apple logo in the top-left corner of your screen and select 'About This Mac'. A small window will appear displaying your current macOS name and version number.
