For use in a package containing all of the McAfee ENS 10.7.1 component ePO installer packages, this postinstall script will install the ENS components in the required order, in kextless mode, then install the PrivilegedHelper tool that was added in 10.7.1

# McAfeeENS10.7.1postinstall.bash
# by Steve Dagley <@sdagley Jamf Nation/Twitter/MacAdmins Slack/GitHub>

# postinstall script for single install package for complete install of McAfee ENS 10.7.1
#
# Incorporate RipOff_Mcafee V2.1 script from MacAdmins Slack #mcafee channel
#
# Requires the package to leave the individual module components in
#	/var/tmp/McAfee/Agent/
#	/var/tmp/McAfee/ENS_TP/
#	/var/tmp/McAfee/ENS_FW/
#	/var/tmp/McAfee/ENS_ATP/
#	/var/tmp/McAfee/DEGO/
#	/var/tmp/McAfee/MNE/
#	/var/tmp/McAfee/FRP/
#
# Flags used in this script
#	/tmp/InstallKextFree	-	If this file exists installs components in KextFree mode
#								NOTE: This flag is now forced on in the script as I see no reason to install
#										ENS in kext mode these days. If you require kext mode remove the line
#										below that reads '/usr/bin/touch /tmp/InstallKextFree'
#	/tmp/SkipMNE			-	If this file exiss then skip installing MNE component (originally added for installs on VMs)
