Hi Guys - I'm having issues doing a clean install of El Capitan. I currently have it installed but I want to do it cleanly to get rid of all the older versions on my computer (2015 MacBook Retina). I watched this video and I'm following everything step-for-step and I'm still having issues. I'm having issues when entering the command into the terminal. I keep getting the error shown (pictures attached). I then tried using Disk Maker X 5 and I get this error. (Pictures Attached). Can anyone help me install this properly/cleanly? Thanks!
