Hey there, I'm on exactly the same issue you had where it says: Ebonys-MacBook-Air:LW-EW-Linux-OSX-v1_0 ebonybowers$ sudo ./install-LW-OSX.sh Password: sudo: unable to execute ./install-LW-OSX.sh: Operation not permitted Ebonys-MacBook-Air:LW-EW-Linux-OSX-v1_0 ebonybowers$ I can see you've put in the edit how you fixed this but I have no idea how to key this in on terminal. Is there any chance you, or anyone else, could send me the bit of text you used to get past this part? Thanks
