In order to give you an accurate answer, we need to know exactly which MacBook you have.
Is it just a MacBook? Is it a MacBook Air or MacBook Pro? And what year was it released?
Find that info by clicking the Apple menu () at the top-left of your screen and then select About This Mac. (Note- for privacy and security reasons, please never post your serial number.)
