    This is a wonderful idea but for some reason I can’t get the shell scripts to work. I’ve tried running them directly in the Terminal and get “zsh: permission denied: /Users/scott/Library/Scripts/Scott’s Scripts/TurnWifiOff.sh” (that’s the path to my script). Trying to use the “Run a shell script” in CCC yields the same result.

    I’ve copied your script from above and pasted it into a BBEdit document, then saved the document as “TurnWifiOff.sh”. Am I doing something wrong with the script? I’m an experienced Mac user and have built many helpful AppleScripts but shell scripts are a mystery to me.

    Any thoughts? Thanks in advance.

      Apologies for the delayed reply. In order to run a .sh shell script, it needs to be set to “executable.” The easiest way to do that, using your file as an example, is to set it to “world executable” (meaning every user can run it). To do that, type the following into Terminal

      chmod a+ x “/Users/scott/Library/Scripts/Scott’s Scripts/TurnWifiOff.sh”

    Regarding Lew’s scripts where he disables Wi-Fi before creating a bootable clone and then re-enables Wi-Fi after creating it, here are the scripts, as promised!

    WiFi_OFF.SH

    #!/bin/sh
    
    /usr/bin/afplay "/System/Library/Components/CoreAudio.component/Contents/SharedSupport/SystemSounds/system/bu rn complete.aif"
    
    networksetup -setairportpower en0 off
    
    

    WiFi_ON.SH

    #!/bin/sh
    
    /usr/bin/afplay "/System/Library/Components/CoreAudio.component/Contents/SharedSupport/SystemSounds/system/bu rn complete.aif"
    
    networksetup -setairportpower en0 on
