How do I completely uninstall 2Do from my Mac?

1. Open Terminal and run defaults delete com.guidedways.TodoMac.
2. Delete ~/Library/Group Containers/EKT6323JY3.com.guidedways, ~/Library/Containers/com.guidedways.TodoMac, and the Helper's container ~/Library/Containers/EKT6323JY3.com.guidedways.TodoMac.Helper.
3. Restart your Mac so the deleted preferences are flushed from the system. If you have CleanMyMac or a similar uninstaller, that's the easier path.

warning

Uninstalling 2Do for Mac removes all local backups stored inside the container. Save a backup from 2Do > Settings > Backups (a backup's ⋯ menu > Save a Copy…) first if you might want your data back.
