MT4 files downloaded

I found some files that end with .ex4 and .mq4 that would help my Techincal Analysis.

I have a macbook, so my operating system is the Mac OS, I had to download Wine program then download MT4, which makes it look like a windows format program. So I downloaded the files, and when I open them by double clicking, it opens the MT4 program but nothing shows up or changes…

Is there any way to solve this issue?
What could be wrong?
