Due to my ownership, praise be to God, of the ability to buy a new one, I preferred to sell the old one and keep the new one, even though I recently changed it and in less than a month its battery and hard drive are new, so I can earn a living and give a warranty on it, and I am sure of selling it safely to the buyer. Finally, for anyone thinking of buying a clean Mac laptop and is serious, call me at ( Phone number appears when clicking the contact button ) .
