Fit note – Please note that the only 2TB drive that exists currently is a 15mm high drive. This means the drive is actually approximately 1mm taller than the drive bay in your Macbook Pro. With this drive in your notebook, the bottom panel of your computer will not fit perfectly flush, as it would with a 12.5mm drive. It WILL protrude on the corner which houses the drive by approximately 1mm, which is very little, but not perfect. You can see an image of the effect below to judge for yourself. Photos in this post are of a mid-2012 Macbook Pro 13. I have also done this install in a 2010 Macbook Pro 13, and the drive bay is slightly deeper, so the fit issue is almost nonexistent – perhaps .2mm
