Soooo first time mac owner here and I watched a few youtube videos and decided I'd replace my own ram. Now I'm reasonably experienced with fiddling with computers, (mostly desktops though) and I thought it looked pretty straightforward. So coming out was easy, putting in however... I couldnt get the bottom one to click when I pressed down so I kept taking it out and putting it in and trying. eventually I heard a click... it was the left tab breaking. So I put it all back together and much to my amazement it still works, and it recognizes the new upgraded memory. I'm curious as to whether anybody has had a similar experience because I know that it part of the logic board and it would cost a bundle to fix. So I might just see how this goes. And if anybody has any advice on how I could fix this should it start diarrhea-ing all over itself. Thanks for the input.
