After sending in my MacBook to Apple for a trade-in, the value was changed to zero due to "Data erasure unsuccessful". I did some research and found other people having the same problems with Apple trade-ins. I decided to look for other places to trade in my Mac and found Go Roostr who offered me more than double what Apple originally offered. The service was incredible, and the team responded very quickly to my questions. They paid for shipping (super simple to drop off the package) and it was the quickest turnaround ever. I got paid the full amount I was quoted the day after they received it and I couldn't be happier with the service!
