I requested a return on this computer within 30 minutes of it being delivered to my house. The charger they sent is not Apple certified so it's overheating to scary levels and the computer will not stay charged. The computer itself is LOUD because of the overheating the fan is on constantly. Theres also this continuous popping sound coming from the computer that only stops when the computer is shut down.  I was SO disappointed because I purchased this for work and I have to wait. I'm concerned about the legitimacy of this company as well. They have my return but will not return the $620 I spent for another 30 days! So I have to wait 30 days until I'm able to replace a computer that I only owned for 30 minutes. It's not worth the risk. Shop with another refurbisher.
