Are you sure you have the Angelbird SSD wrk for Mac?
B&H offers the SSD wrk. I think you must have a different model. I have the one for mac and there it says TRIM Support = Yes
Hmm.. Probably not. Where did you buy yours from?
Their site doesn't allow direct US shipping.
I'm in the UK, but looks like they ship to the USA, since it's in the drop down list in the country select on the Angelbird web site
In the same boat as you, bought a 256GB wrk last week from B&H right after reading this thread. Angelbird support said I need the "SSD wrk for Mac," and I should contact B&H about an exchange. They would have the Mac drives in stock "soon." A firmware flash wouldn't be available for my drive, either. Probably more trouble than I'm willing to go through with the exchange process, bummer that it wasn't clearer.
I returned mine to B&H and ordered from Angelbird direct, set to be delivered tomorrow.
That's not the angel bird cos it spoofs the geniune Apple drive to bypass this charade of third party trim.
I am surprised Apple haven't sent their lawyers in, but I fear with a fair use defence and being blatantly unfair that we have to disable signed drivers they might have lose that case and end up and being forced to enable third party SSD trim for all of the popular SSD models.
Couldn't come a day sooner - it's utterly ridiculous by Apple enforcing it after Yosemite..
You could always not bother, install a small Mavericks partition with trim enabled and use disk utility/repair disk to trim the drive from the 10.9 recovery partition - until this farce is over!
If you are wanting to put an SSD in a Mac to get the benefit of the TRIM function then make sure you buy the Angelbird SSD wrk for Mac, not their regular wrk model, as that doesn't offer TRIM for Mac.
From my understanding I want the Samsung based Apple SSD for the fastest read/write performance right?
But I can't seem to find any of those on eBay.
how do the Toshiba ones compare in terms of performance? As I see quite a lot of those available.
Received two Angelbird 'wrk for Mac' 512GB SSD drives from Austria (package said Germany).
TRIM does work as advertised!! Speeds are not bad either.

For now Whats so say Apple breaks it with future updates.

Then, that could likely break TRIM on some of their real SSDs.
Do you think they'd be willing to take that risk?
I've updated my OS to 10.10.1 and my Angelbird SSD for Mac is working with TRIM function enabled.
No, these are just standard 2.5" laptop drives. Your Retina uses a "blade" style storage module that looks like this.
Take a look at Transcend. The make a replacement drive for your Retina.

angelbird was a big option for me because of the trim support
are there any other blade style storage SSD's that do enable trim?
So if I were to buy one of these drives, all I have to do is physically install the drive into my 2012 MBP and then clone my old drive? No tricks or hacks? I'm a noob when it comes to SSDs

Yep... format the new drive then clone old to new and restart. After restarting go to System Prefs and in the Startup Disk pane select the new drive as the boot drive and you are done.

Not without running the TRIM enabler "hack."
How about that 'Erase Free Space' button in Disk Utility? Isn't that sort of TRIM-on-demand we could use once a month or so? I would guess so, since it erases unused space, as a security measure to prevent the recovery of previously written data. Wouldn't that enable GC to weed out unused pages/blocks?
