No Touchpad after 10.15.3 update

Anyone already found a fix for this?

Did you update using the system settings? Touchpad also didn't work for me via updating like that. Instead, I had to make a fresh install of MacOS Catalina 10.15 onto the SSD; after that, everything worked. I'm guessing it's a security feature update that causes the issue

I can't seem to reproduce the same issue.. even though I updated from system settings.. maybe rebuild the kext cache using sudo kextcache -i /

How to update from system settings?
I have updated and restarted the machine and do not show the mac drive in clover....

@duongdpq : you should see an extra disk in clover that says something like "install macOS" or something. Choosing that should update your MacOS. If your MacOS drive is completely gone, then... i hope someone else might know the answer
