Getting Jpcsp to work on a mac; can't find umdimages folder

[Savvylee]

I think I'm gonna try using a different file extractor and see what that does.

And also my dad gave me the mac, it's like 7 years old. I don't want to buy the console because it's old and P3P is really the only game that I care about playing on it.
Thanks for your input anyway.

EDIT:
I finally found it omg I put it on my desktop and I clicked "Show Package Contents" and I found the folder!! But now I have a new problem. I put the iso in the umdimages folder but when I try to open it on the emulator it doesn't show up. My mac says it's a normal document and not an ISO disk image. Is it the iso itself or do I have to do something to it

The file says .iso.torrent. What do I do with it?
