I have a good as new 15-inch Retina MacBook Pro that I don't use anymore, as I have switched to Windows and Android. The machine still works as wonderfully as it did when it was brand new, it's very fast at every day use thanks to the SSD and processor. It currently has a dBrand mahogany skin on it, that can removed easily. Also comes with a grey sleeve by Incase, and the original box with all the accessories.
