I have a mid-2011 21.5" iMac (EMC 2389) and I am trying to remove the stand. I'm trying to follow this guide but I can't seem to find the "latch" that he talks about. I heard that any iMac past 2011 doesn't have a removable stand; this is a 2011 model. Is the stand even removable (whether or not in this manner) and if so how would I go about doing it? Thanks!
iFixIt.com have some of the best step-by-step guides for repairs on just about any Apple device.
I found their guide for removing the stand of your iMac here: https://www.ifixit.com/Guide/iMac+Intel+21.5-Inch+EMC+2389+Stand+Replacement/113471
I see it as a little bonus that it's based on steps - that way you don't have to pause the video multiple times.
