Older iMacs had magnets to keep the screen in place. Wouldn’t it be possible add magnets to the newer iMacs which have the screen glued on? So that when you have to open your iMac the first time, you do not glue it back together but glue in some magnets and some metal and simply snap the screen back in place?
Nope, there’s no room. The earlier iMacs has room for a metal plate all around the display and room for magnetic pins. This one does not have the room nor thickness to alter it.
What about magnetic tape? https://www.amazon.com/Flexible-Magnetic… I have not tried this myself but I will probably try it next time I have to open up one of these iMacs. Although honestly, I try very hard to not bother. The main thing people want is a larger/faster hard drive and it’s better to use an external (in most cases an SSD) rather than going through the hassle of messing with cutting then replying adhesive.
