Create a weekly or specific date alarm to wake you with your favorite music or any of the built in sounds.

Fall asleep with the sleep timer, which can also put your Mac to sleep.

Use the egg timer for quick one-time alarms like taking a quick nap or timing the oven. Let your Mac sleep through the night. Awaken will handle waking your Mac at alarm time.

If  iTunes has a problem at alarm time, the backup alarm will wake you.
