Todolicious

Todolicious is a beautiful and simple task list for your Mac that helps you actually finish your tasks.

Todolicious does not ask you to categorize or organize your To Dos; simply add your tasks and check them off, and it will manage everything for you. And it will even cheer you on when you finish a To Do.
Stop wasting time meticulously tagging and scheduling your To Dos, and spend more time doing them.
Todolicious has system-wide keyboard shortcuts for adding new To Dos so you can get your next task out of your head quickly. There is also a keyboard shortcut for creating new To Dos and quickly showing/hiding your To Do list.
Todolicious has three beautiful styles to choose from, including a light, dark, and notebook styles. Your To Do list is your personal brain dump, so keep it styled the way you like it.
