Hello all, I was wondering if there was anyone who has had any experience in opening up the post-2012 iMac with the adhesive instead of magnets.. I have a memory kit to upgrade my installed 8GB to 16GB but I did not order the adhesive strips to go onto the display. My question is: do I actually need to scrape off the old adhesives and attach a new one in a kit like this or is it possible to just reattach with the residual adhesive from factory? Any help is most appreciated. As well as any pointers for easier install while inside if you've done it before!
