Once installed, quit your terminal window, delete the bash-fix folder from your user home folder, and start again from the beginning. I've updated the article to reflect this. I downloaded Xcode, opened it no problem, did all the steps above and updated my bash, then reset the default But I still get 'vulnerable' this i a test.

Should i just delete that with normal Finder Trash? So even though I haven't yet installed the second-level patch, my 3.
