Dent.

So a few months ago my mom was using my MacBook Pro, and she apparently dropped it or something. One of the corners is completely dented, and scrapes against the other half of the computer when I open it.
I'll attach some pictures below. Is there any way for me to fix this problem without completely screwing up the computer or anything?

Apart from taking it to apple then file it so it doesn't catch.

Get your Mom to make a claim under her home and contents insurance polify. Sometimes accidental damage is covered.

Mine is dented on the back corner in a very similar fashion (oddly enough). It doesn't catch when I open it or close it. You can't really tell it's there unless your looking at it while it's closed. I left it like that. I was tempted to bend it back, but then realized there is a high possibility of breaking the glass while doing that. I would just leave it, if it doesn't hamper the machines ability to function, then leave it be.
