Thanks for the fast reply. So I copy the contents of the .dmg file to a folder in my 'Applications' folder, then follow TJW's setup... When I'm in terminal, and I run ./tremded blah blah it returns './tremded: Permission denied.' I'm an admin on my iMac but I have no idea how to work with Terminal, besides how to type stuff in. Is there a way I can grant myself permission to execute files in Terminal? :-?
