Texturing and Folder Finding (Mac)

[bbqd]

So I've been working on my first mod from this tutorial:

and I can't seem to find the user.gradle folder (13:00 in the video) to start making textures. Where is this folder on a mac?

 

NOTE: While waiting for a response, I made a test texture in GIMP (a 16x16 pixel png) and put it in the "firstMod/src/firstMod/assets/firstMod/textures/items" folder, but it just shows the purple and black default picture when I try to run minecraft with the mod. What happened and how do I fix it?

1) The only bit that's not working is the texture, the item itself is there.

2) I moved the texture to src/main/resources and it still didn't work.

3) why did it work in the video?

Thanks for helping so far!

Thanks so much, I changed my modid to all lowercase and it worked! I have one question left regarding file structure, but that would involve posting a screenshot(I don't have internet at the moment and am writing this with my phone...), so I'll try and have that up in an hour and a half or so.

 

NOTE: Okay, never mind, the picture didn't want to be inserted into the thing! Anyway, how should I set up my packages and directories? Right now, inside of the main minecraft folder, I have the packages "assets.firstmod.textures.items" which contains the item textures, "net.firstmod.mod" which has my main FirstMod.class, and "net.firstmod.mod.items", which has a template class for setting up Items.
