Arduino library MAC problem!

Hello!

I'm trying to make out a little project but for this I downloaded some new libraries to write down the sketch for arduino.
I am using a MAC, and the problem is that Arduino cannot recognize the libraires I am trying to work with.
I put the in the sketch folder and nothing, I do not know why is not working, it always say to me that the commands I am
trying to use does not exist, when is supposed that I included the library with the commands.

Please help!
Thanks! :grin:

I think you mean a "Mac". Mac isn't an acronym.

Libraries go into:
~/Documents/Arduino/libraries/

Make sure the library's contents are in their own directory.

Uh right!

Thanks the problem was that I did not create a folder with the library name into the "libraries" folder. I
just put the libraries in there. So easy that I couldn't recognise it.

And yes I meant a Macintosh my bad, for fast typing.

Thanks for your help, I was getting mad!!
