Hello. This is my first post; I have come across a problem and I hope someone can help me. I have just received some new memory for my laptop, so I decided to install the memory. I am not very familiar with installing memory on a Mac, but the instructions seemed pretty straightforward and simple, so I attempted it. I saw the picture on the right hand side next to the memory slots (the one with the 25 degree angle), so I lifted the first one out easily. The one at the bottom, I just tried lifting it up with force; I believe that I was suppose to slightly lift and pull. I saw a small crack on the bracket arms, and I panicked. I put in the first bottom module, but instead of locking down, is pushed slightly upwards. The top one locked in fine. I decided to just go with it and turned my computer back on. My Macbook is able to read the memory, but I have a concern. By not having my bottom module locked in securely, will that create some issues in the future? Help will be appreciated. Thank you.
