Amnesia Editor for mac, How To?

[nivramm]

the biggest thing i need is what script app do i need?

Would be best to use a texteditor, in which you can add a custom tag list for autocomplete.
This is a list of tags, very useful.
I personal prefer Geany, just found a port for MacOSx - don't know if it works proper.

If it does, here is a quite good tutorial on how to set it up for .hps; including the taglist above.
Good Luck
