My Custom Story won't show up...is it because of my mac???

[Your Computer]

It's because TextEdit by default is a word processor. Word processors tend to save in RTF (rich-text format). Notepad is an plain text editor and does not save in RTF but ASCII. That is why it works when you use Notepad.

In your other topic i linked you to a page on how to get TextEdit to save in plain text format. That should have solved your issue.
