@Zeek if your trying to do this on a 10.11.x Mac I don't believe it will work because of System Integrity Protection.

Have you looked at a config profile? There are options to restrict external storage devices to read only, or no access at all..

If I run this one it will move this single extension to the JAMF folder:

if [ -d "$targetVolume/Library/Application Support/JAMF/DisabledExtensions/" ]; then
/bin/mv "$targetVolume/System/Library/Extensions/IOUSBMassStorageClass.kext"

But I need all of those moved:
1.IOUSBMassStorageClass.kext
2.IOFireWireSerialBusProtocolTransport.kext
3.OUSBAttachedSCSI.kext
4.OUSBFamily.kext

If I manually go to System/Library/Extensions and delete those four extensions it will work.

I'm not sure this is a great idea, but in terms of getting the script working:

#check if the directory exists, if not then create it
[ -d "$targetVolume/Library/Application Support/JAMF/DisabledExtensions/" ] || /bin/mkdir -p "$targetVolume/Library/Application Support/JAMF/DisabledExtensions/"
#check if each file exists, if so then move it to the disabled directory
[ -e "$targetVolume/System/Library/Extensions/IOUSBMassStorageClass.kext" ] && /bin/mv "$targetVolume/System/Library/Extensions/IOUSBMassStorageClass.kext" "$targetVolume/Library/Application Support/JAMF/DisabledExtensions/"
[ -e "$targetVolume/System/Library/Extensions/IOFireWireSerialBusProtocolTransport.kext" ] && /bin/mv "$targetVolume/System/Library/Extensions/IOFireWireSerialBusProtocolTransport.kext" "$targetVolume/Library/Application Support/JAMF/DisabledExtensions/"
[ -e "$targetVolume/System/Library/Extensions/IOUSBAttachedSCSI.kext" ] && /bin/mv "$targetVolume/System/Library/Extensions/IOUSBAttachedSCSI.kext" "$targetVolume/Library/Application Support/JAMF/DisabledExtensions/"
[ -e "$targetVolume/System/Library/Extensions/IOUSBFamily.kext" ] && /bin/mv "$targetVolume/System/Library/Extensions/IOUSBFamily.kext" "$targetVolume/Library/Application Support/JAMF/DisabledExtensions/"

Or clean it up with an array and a for loop:

#check if the directory exists, if not then create it
[ -d "$targetVolume/Library/Application Support/JAMF/DisabledExtensions/" ] || /bin/mkdir -p "$targetVolume/Library/Application Support/JAMF/DisabledExtensions/"

#place file names in an array
declare -a KEXTArray=("IOUSBMassStorageClass.kext" "IOFireWireSerialBusProtocolTransport.kext" "IOUSBAttachedSCSI.kext" "IOUSBFamily.kext")

#for each file name in the array check if it exists, if it does then move it.
for KEXT in "${KEXTArray[@]}"; do
    [ -e "$targetVolume/System/Library/Extensions/$KEXT" ] && /bin/mv "$targetVolume/System/Library/Extensions/$KEXT" "$targetVolume/Library/Application Support/JAMF/DisabledExtensions/"
done

Note: the >_ symbol in the JAMF nation posting tools is the script block, it makes it easier to read code.

Self service pop up saying there was a problem with the scrip.

Here is the full scrip:

# ABOUT THIS PROGRAM

NAME

disableUSB.sh -- Disable the USB drivers.

SYNOPSIS

sudo disableUSB.sh

sudo disableUSB.sh <targetVolume> <computerName> <currentUsername>

DESCRIPTION

This script disables the USB drivers, thereby disabling all functionality of the USB ports.

After running this script, the USB drivers will be moved to:

/Library/Application Support/JAMF/DisabledExtensions/

This way, the USB drivers could be re-enabled in the future. After running this script,

the machine will need to be rebooted for the settings to take effect.

@Zeek Pretty sure that those .kext locations are in som manner SIP protected.

So doubt this will work with 10.11.

+1 Config Profile or MCX if you like

+1 for SIP will stop you

$ ls -lOe /System/Library/Extensions/IOUSBMassStorageClass.kext

Does anyone have a good solution for disabling USB for certain groups?
