Inconsistent KEXT Status Between System Information and kextstat

Hello Everyone,

I have noticed an inconsistency in the KEXT status between the System Information Extensions section and the output of the kextstat command.

In System Information, the extension appears as loaded:

ACS6x:

  Version:        3.8.3
  Last Modified:  2025/3/10, 8:03 PM
  Bundle ID:      com.Accusys.driver.Acxxx

                  TeamID: K3TDMD9Y6B

However, when I check using kextstat, it does not appear as loaded:

$ kextstat | grep ACS6x

Executing: /usr/bin/kmutil showloaded
No variant specified, falling back to release

I use a script to do these jobs

echo "  Change to build/Release"
echo "  CodeSign ACS6x.kext"
echo "  Compress to zip file"
echo "  Notary & Staple"
echo "  Unload the old Acxxx Driver"
echo "  Copy ACS6x.kext driver to /Library/Extensions/"
echo "  Change ACS6x.kext driver owner"
echo "  Loaded ACS6x.kext driver"
    sudo kextload ACS6x.kext
echo "  Rebiuld system cache"
    sudo kextcache -system-prelinked-kernel
    sudo kextcache -system-caches
    sudo kextcache -i /
echo "  Reboot"
    sudo reboot

But it seems that the KEXT is not always loaded successfully. What did I forget to do?

Any help would be greatly appreciated.

Best regards, Charles
