From the dimensions of her torch fits exactly where the original SuperDrive Apple plugged. With a little sleight of hand on the basis of instructions, for example, Youtube, it is possible to expand the original burner.
And by then you realize that the two devices but are not quite identical, as alleged by the supplier! Because the original SuperDrive has a longer tab with two holes to fix the burner on the spot in the case to the lower front edge where the slot is located on the MacBook Pro.
Although these two screws are not the only ones with which the device is mounted in the housing, I think that without these two fixing points of the burner would sit loosely inside the Macs. This point is the most critical, because if the torch slipped over time, you can see the silver discs no longer load (push), or they are scratched.
The only way to master this little, or big problem is connected with other work! Namely, you have to cover the floor of the burner switch to the downside that the warranty by opening the new burner goes out !!!
On the one screw that is glued to the warranty label of the appliance. Without the screw unscrewed, you can not remove the lid.
You have to decide if you have a loose burner with guarantee in your Mac have want, or a permanently installed with no guarantee you so.
Without knowing whether the Apple operating system the new Blu-ray burner realizes I took the risk and was not disappointed.
The drive is recognized by the system restarts immediately and functioning properly.
Because of the inconvenience I forgive only 3.5 stars.
