Uninstall FortiClient on macOS using script

Hi all,

I'm trying to uninstall FortiClient on macbook with M1/M2 processor using a script from this article: https://community.fortinet.com/t5/FortiClient/Technical-Tip-Uninstall-FortiClient-using-a-script-on-...

I only added two lines to change flags. Here is my script:

 

#!/bin/sh
# Uninstall FortiClient.sh

pkill FortiClient
launchctl unload /Library/LaunchDaemons/com.fortinet*

chflags -hv noschg /Applications/FortiClient.app
chflags -hv noschg /Applications/FortiClientUninstaller.app
rm -Rfv /Applications/FortiClient.app
rm -Rfv /Applications/FortiClientUninstaller.app
rm -Rfv /Library/Application\ Support/Fortinet
rm -Rfv /Library/Internet\ Plug-Ins FortiClient_SSLVPN_Plugin.bundle
rm -Rfv '/Library/LaunchDaemons/com.fortinet.forticlient.vpn.plist'
rm -Rfv '/Library/LaunchDaemons/com.fortinet.forticlient.wf.plist'
rm -Rfv '/Library/LaunchDaemons/com.fortinet.forticlient.fmon.plist'
rm -Rfv '/Library/LaunchDaemons/com.fortinet.forticlient.epctrl.plist'
rm -Rfv '/Library/LaunchDaemons/com.fortinet.forticlient.appfw.plist'
rm -Rfv '/Library/LaunchDaemons/com.fortinet.forticlient.fssoagent_launchdaemon.plist'

localAccounts=$(dscl . list /Users UniqueID | awk '$2 > 500 { print $1 }')

for user in $localAccounts ;
do
	rm -Rfv /Users/"$user"/Library/Application\ Support/Fortinet/
done

 

But I got error that deleting FortiClient.app and FortiClient.app\Content is not permitted, because application is locked. At this time, FortiClientUninstaller.app has been deleted successfully:

 

chflags: /Applications/FortiClient.app: Operation not permitted
/Applications/FortiClientUninstaller.app

 

Could someone help me with this issue, please?

The problem was solved by providing full disk access to Terminal

Hello Webster

I think this is a MacOS security related question, right?

Did you try from single user mode?

Hello AEK,

I didn't try, because I need to execute this script via MDM solution to multiple devices. I had the same problem with GUI uninstaller of FortiClient, but after adding string with changing flags, this problem was solved
