Hey guys this is my first mac. It's a retina macbook pro working flawlessly. However, when I pick it up or apply a little bit of pressure, I hear some tiny pops that aren't really major. I noticed that when I push the bottom cover in, it goes in a little bit, which means the screws could be a tiny bit loose (there's a tiny tiny gap between the bottom cover and the top.) I don't know this is normal, but I read somewhere that it could be because the components are getting used to the heat expansion and stuff, and this popping noise should disappear in a few months. It's my first mac, so I can't judge but let me know what you guys think.
