Computer was extremely slow on startup from the very beginning Purchased from Amazon with a 1TB drive., worked with Dell support where it was determined that the issue was the hard drive, I was informed that  since the computer was purchaed through Amazon, they would only replace the HD with a 128 SSD. After multiple calls with Tech support, and discussions with Apple the decison was made to return the computer for a refund.Since it was 30 days beyond the purchase date, Amazon wanted a 97.00 research fee dispite the fact that Dell had already determined that the issue was the HD.
