Custom Storys and my Mac...Need help please!

[Mechanix2]

So I've spent 3 hours scouring the Internet looking at how to Install Custom Stories on my Mac...I've downloaded Gary's Dark Descent, and Tenebris Lake and have both of them extracted to my desktop. I've put both of those folders inside the "custom_storys" folder located in Applications > Amnesia > Content > Resources > Custom_storys but whenever I go to launch Amnesia the CS's are not there. I've looked up Youtube Vids, Googled Forums..I do believ eI've done everything right, but am i missing something?? Currently running 10.7.4.

Any feedback is greatly appreciated!
