    Does not work. Now my 24
    FIrst of all, it didn't come with an access card to engage the latch behind the mac. i was able to remove my imac stand but now my imac latch is locked into the down position. I have been trying for 2 hours and looking for a solution at and youtube but nothing is working. now i might have bring in my Imac at the apple store to get it fixed and will probably cost me a couple hundred dollars. I just wanted to add that i am a computer tech. I work on PCs, laptops and servers all the time and this mount just frustrated me

    PROS: I was so happy that i found an Imac adapter plate this cheap. Unfortunately, it was too good to be true. It was cheap and looks well made

    CONS: Didn't work for my 24" Imac

    Works great!!
    Purchased to attach a 27" iMac (Late 2009 model) to a pole-type stand to lower the overall height of my iMac (it was too tall with the original Apple® base).

    As a side note, my experience mounting the iMac to the pole-type stand was not so good (but is totally unrelated to this adapter plate). The problem is getting a mount strong enough to hold the weight of the iMac. For more information on this please see my review of Monoprice 105970 Adjustable Tilting Monitor Desk Mount Bracket Max, Black

    PROS: Very solid, well-constructed, and fairly easy to install.

    Tilts/operates just like the the original Apple® base.

    Better price than Amazon!

    CONS: None

    Working fine with my 24" iMac
    It works, what more to say

    Be sure to buy the heavy duty Mount 9378 gpt s 24" or above, I'm using a table mount and it's crying. I'm ordering another 9378 for this one as they work well for so many large LCDs.

    PROS: Gets the job done, works as advertised, Allows me to loose the base on my 24" iMac

    CONS: Not as sharp edged as my Mac. Ascetically not as attractive (but honestly who stares at the back of the Mac)

    Good, if you have the correct instructions
    I had a bit of a misadventure while installing this, as the instructions don't say to use the access card to open the interior latch in order to move it back into position. I suspect this is the source of all the reviews that state that the screen was always tilted forward - because this crucial step is missing from the directions.

    Anyway, between the problems from that and the problems of another reading of the instructions causing me to end up with the internal flange getting stuck inside my monitor (and having to fish it out with some very stiff wire and a LOT of elbow grease) I've ended up slightly damaging the internal hinge, and since the monitor stand I got wasn't quite right for my space I went back to the stock stand - which now makes a slight metal-on-metal grinding sound when I tilt the monitor.

    The bracket itself didn't damage my monitor, I did, but I did as a result of trying to follow the incomplete directions. So, that's pretty frustrating.

    But anyway, if you want to mount your iMac or Thunderbolt display to a VESA stand, this is perfectly fine. Just know that there's a very simple step missing from the manual - you have to use your access card to open the latch not just when removing the stock stand, but when putting the new stand into place as well.

    Also, as an aside, the manual says to make sure that you tighten the screws to the VESA plate all the way when you mount the monitor. This is a great way to strip the screwholes, as I found out, as the metal is quite soft.

    PROS: Does exactly what it says on the tin

    CONS: Incomplete instructions make it easy to screw up also, metal is soft and it's very easy to strip the screw holes (especially when following the directions)

    Very Difficult to remove!
    i bought this adapter a couple years ago to mount my 27" iMac to a monitor arm. It was much cheaper than the Apple option, so I bought it. It worked great for a couple years, but then the monitor arm failed and I needed to re-attach the stock stand.

    Recall how you removed the stand: Pull up on the stand, slip the card in to pull the latch, then push all the way down to expose the screws. This is very easy with the stand attached, because you have the leverage of the entire stand.

    When you try to do the same to remove the adapter, you DO NOT have the leverage. I had to bolt the VESA bracket back onto the adapter, then bolt part of the broken monitor arm onto the bracket in order to get the leverage needed. With the adapter bolted on, it is very difficult to get the card into the slot to release the latch.

    Once you install it, you should leave it locked in the "screws exposed" position, which is probably how it is meant to be installed. I didn't do that and what a PITA.

    PROS: Price

    CONS: Removal is very difficult

    Not good for the big imac.
    So I have fought with this all day long and I am fed up. Basically if you look at how the apple product works it blocks out the tilt entirely which this product doesn't. By not locking out the tilt you can literally turn your imac flat and spin it around. I can't get the 27" imac to stand up. It just slouches forward. Unfortunately this isn't a knock off of the apple product which looks like I wouldn't have to struggle with. Again with the lighter unit and with perhaps a different bracket you might have better luck. I didn't and I have hung a bunch of TV's and use my mounting bracket with monitors (much lighter) than the iMac.

    Response from Monoprice
    Hello Heffneil,

    Thank you for your review and my apologies for the issues you have experienced with PID 9899. A shame this didn't work out for your needs.. Now if you'd like, I can help setup an RMA for a return. If you would like me to proceed with the RMA, all I would need is the order # this adapter plate is under. Sorry again for the trouble and thanks in advance!

    Do not buy this if you have a 27
    I never write reviews but I am so frustrated by this I had to help other folks avoid this pain.

    If you have a 27" imac save yourself the trouble and buy something else.

    PROS: cheap

    CONS: Does not support the 27" iMac, the weight of the 27" is too much for this mount adapter, even though it is rated for 33lbs and the 27"iMac 2011 weights 30.5lbs this adapter had the monitor leaning all the way forward in an unusable position.
    More importantly it is nearly impossible to get off once it is attached. I have been trying for 2 days, searched help forums and youtube to no avail.

    Does not work with new 27". The mounting stand can not be removed therefore this will never work. Good think monoprice issued a refund but I am out the shipping cost for a product they should not be selling for a 27" iMac

    PROS: monoprice

    CONS: Does not work with new 27".

    Doesn't work for 2009 27
    When installed, my 2009 27" iMac tilts all the way forward. Maybe this will work with lighter models (2013 and later) or with 21" iMac models, but not for the heavy (30.5 lb) 27 inch iMacs. Because I didn't get around to installing it until after 30 days, I only get a merchandise credit and have to pay return shipping. Annoying. For a design flaw, I would have thought they would make an exception. Most things I have gotten from monoprice have been good. But not this time.

    Did not fit my 24-inch LED Apple Cinema Display
    I bought this for my Late 2008 24-inch LED Apple Cinema Display. The adapter was too narrow for the slot in the back of the display that the stand goes into, by about 1/4" on each side. I had to grind either side down in order to get it attached and working. It now seems to be working fine, but I can't understand why it was too wide to begin with. Even if later models of displays and iMacs feature a wider slot, given that all of the screws line up correctly, why wouldn't you just use the narrower width?

    PROS: Price compared to alternatives.

    CONS: Didn't fit.

    Will this work with a late 2013 27" iMac (EMC 2639)? There are no years mentioned in the supported model section and others leaving feedback aren't always calling out their model's year.
