"How to put the original Apple led stand back after removing Vesa?"に関する回答This discussion was incredibly helpful to me, particularly the part where it said the latch is not deep in. Still, I was unable to get the latch to operate until I used an idea from another thread on this subject. I used an icing spreader, which has a thin stainless piece of metal on a wooden handle. It isn’t sharp, and has a rounded end. It was thin enough to go in the gap, and stiff and strong enough to move the latch.
