Which internal Blu-ray drives are compatible with a unibody Macbook Pro?

The following YouTube video by breakbeet808 confirms that

... It is now possible with the Panasonic/Matshita UJ167 9.5mm slot-loading BD-ROM drive, and/or the UJ-267 BD-Recorder drive, and some extra software: Mac Blu Ray Player from MacGo.

However, these blu-ray drives are not a "100% direct swap out replacement":

There is a slight difference with some mounting points on the top side of the drive. The problem is solved by swapping the drives' upper casing out.
(see "How to upgrade to the Panasonic/Matshita UJ167 drive")

Once you finish the upgrade, OS X will "recognize blu-ray discs and it will be available to the file system like any other optical disc".

How to upgrade to the Panasonic/Matshita UJ167 drive

This may void your warranty. Try this at your own risk.

1. Remove the original superdrive. (You can follow instructions by ifixit, for example.)
2. Remove the top metal shell of the drive itself, by removing its four screws. You'll also have to peel off a strip of silver tape that connects the top shell to the bottom shell. This will expose the internal guts of the superdrive. It's this top metal shell that we need to keep, it has the mounting holes in the right spots, so be very careful not to damage it. Do not touch any components inside of the drive. You may want to look up how to do this, it's a little tricky to free it up successfully.
3. Now remove the top metal shell of the new blu-ray drive in the same fashion.
4. Swap out those top metal shells, and screw the drives back together. The top metal shell from the original superdrive should now be on the new blu-ray drive.
5. Now also swap out the small Y shaped mounting bracket from the plug-side of the superdrive and screw it to the new blu-ray drive - those two screw holes do match up exactly already.
6. Carefully unplug the flexible data connection cable from the old superdrive and plug it onto the new blu-ray drive.
7. Reinstall blu-ray drive.

Edit: Slimline drives are 12.7 mm thick; Super-slimline drives are 9.5 mm thick (these fit in current portable Macs smaller than 17")

Physically these two should fit for slimline dimensions (12.7 mm) - don't know about the software support (I guess it will be difficult to find someone who actually uses an internal Blu-ray drive in a portable Mac):

TEAK BD-C24SS-A slimline BD combo drive

• Slot Load «Combo-drive», plays Blu-ray disks (no recoding for Blu-ray), writes DVDs & CDs

Sony BD-5850H slimline BD burner

• Slot Loading Mechanism, Max. 6x BD read, 6x BD write, Max. 8x DVD+/-R read/write, S-ATA interface

You would have to remove the plastic bezel/cover (which is normally not too difficult).

Wonderful question! I am looking to do the same thing and found it difficult to find the right drive so that the wireless card will fit nicely over the top. So after a little searching, here is a Panasonic as well as the Sony drive perviously mentioned, these should both fit perfectly (with a little thinning down aka removal of the sony faceplate). So now we have the drive. If you are going to be installing this yourself there is a great walkthrough on drive replacement over at iFixit. Luckily apple got with the standard and any macbook 2009 or later will have a SATA hook-up which fits our replacement blu-ray drives. As far as software goes, the web is an endless source for compatible software. Although, VLC is a great media player that will handle blu-ray playback in keeping with a comfortable GUI.

For the software, I have to say you won't be able to play a Blu-Ray drive onto your Mac since their is no decoder for Mac OS X integrated.
However, you can play your Blu-Ray movies by using Windows. And of course, some clever guys did find a work around to play Blu-Ray movies onto your Mac.

For the hardware, it seems it's pretty hard to find an internal drive with a 9.5mm hight to fit in your 15" MacBook Pro. Take a look at this picture with the supported models:

It seems like Apple, with his eagerness to design the thinnest notebooks, has made it almost impossible to install an internal Blu-Ray drive inside a Unibody MacBook Pro.

Their are some with 12,5mm in height, but they will only fit in a 17" MacBook Pro. And since you mentionned the height of 9.5mm, I assume it's a 15" MacBook Pro you're talking about.

So in my opinion, it's not possible to fit an internal Blu-Ray drive into a 15" MacBook Pro Unibody. It's like Steve Jobs said once, Blu-Ray is a bag of hurt (to implement it in a Mac).

I think you should look out for an external one. I would recommend one with maximum versatility, one with Firewire, USB, and eSATA connectivity.

A quick look at OWC doesn't show any internal BR drives for portable Macs, only in 5.25" format. CDW only shows a single model internal BR drive, and I doubt it would work well in anything other than its intended laptop.

So I don't think a compatible product exists.

That said, I have a LaCie BR external drive that I occasionally use with my MBP 15" as well as other Macs around my office (including file servers). It's not an internal, but its small, fast, and reliable.
