Annoying uninstalling files on mac 10.10.2? Help?

,Before you go into the comments and send me a link to some other question and answer please listen to my situation.

When I searched for Unistalling UE4 because it is huge and is too much for my mac computer (I can only run it at about 15fps) I got this: How do I uninstall UE4 on a Mac? - Getting Started & Setup - Epic Developer Community Forums .

This, as it turns out is useless. I have found files. but the largest found is 134mb. I thought I would ask you before deleting them, just in case. On my operating system I cannot find the actual unreal engine even with help from that link.

Should I delete the files? Will that overall get rid of unreal engine? Please help…
