Not sure if anyone is still looking for this info. But apple will swap the stand for vesa mount and vise versa. The cost is $119 for VESA mount and $99 for labor as they claim this repair is “out of warranty” they will also return the stand to you and it’s $99 if you ever want to swap it back.apple care + has no bearing under it they tried to get the labor waived but apples system wouldn’t allow it. Here is the service receipt to go from tilt stand to vesa mount
they also offer it as a self service repair but not sure what that cost is.
