Isn't TextEdit sandboxed in Lion + Mountain Lion? If so TextEdit most likely cannot execute any non signed code or open a network connection... But of course sandboxing should only be used as a last resort. I am not a security expert - can anyone comment on that?
My .txt's open with Sublime, which is not Sandboxed (or maybe is, I don't know). They can't de-quarantine .txt's because the default is to open with TextEdit!
