The current workaround is to uninstall "Encryption Management for Apple FileVault":

 
Uninstalling the Encryption Management for Apple FileVault agent requires access to the Mac OS X Terminal application.
 
  1. Go to Applications > Utilities and double-click Terminal.
  2. Do the following:
    • For endpoints with hard drives not using APFS (Apple File System):
      1. Type cd /Library/Application Support/TrendMicro/FDEMM
      2. Type sudo ./Uninstaller
         
        During automated uninstallations on Mac OS X Yosemite, the user must confirm that they want to restart the endpoint if the the device requires decryption before uninstallation. To automate this confirmation, users can append the parameter RebootWithoutConfirm.
        The following is an example command that automates restart confirmation:
        sudo ./Uninstaller RebootWithoutConfirm
         
    • For endpoints running Mac OS High Sierra (10.13) with SSDs using APFS:
      1. Type sudo /Library/Application\ Support/TrendMicro/FDEMM/Uninstaller
      2. Type the user name and password of the user currently logged on.
  3. The agent uninstalls in the background.
  4. Restart the endpoint to complete the uninstallation.

If Option 1 doesn’t work, customer can do the following:

  1. Go to Applications > Utilities and double-click Terminal. The Terminal window appears.
  2. Type the following:
    sudo pkgutil --forget com.trendmicro.fdemm
    sudo launchctl unload /Library/LaunchDaemons/com.trendmicro.fdemm.daemon.plist
    sudo launchctl unload /Library/LaunchDaemons/com.trendmicro.fdemm.UI.plist
    sudo rm -f /Library/LaunchDaemons/com.trendmicro.fdemm.daemon.plist
    sudo rm -f /Library/LaunchDaemons/com.trendmicro.fdemm.UI.plist
    sudo rm -rf "/Library/Application Support/TrendMicro/FDEMM/"
    sudo rm -rf "/Applications/Encryption Management for Apple FileVault.app"
    sudo rm -rf /var/tmp/tmee
    
     
    Uninstall mono framework if it is no longer used:
    sudo pkgutil --forget com.ximian.mono-2.10.11
    sudo rm -rf /Library/Frameworks/Mono.framework
