Why is my new Mac acting weird?
Replace the battery: If you have a new Mac, you won’t run into system battery problems for years. But if you have an older Mac that is behaving weirdly — a common symptom is the wrong date at startup — the small battery on the motherboard that keeps the clock and PRAM working might have run down.

How do I reset the PRAM on my Mac laptop?
Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R. You can release the keys after about 20 seconds, during which your Mac might appear to restart. On Mac computers that play a startup sound, you can release the keys after the second startup sound.
