Do you know if the latest Hackintool automatically places the kext in the right folder for OSX 10.15.3 ?
Updated. The only issue was on the Clover bootloader. You have to pick the "install" option on the Clover (2 times in my case) to follow up the update installation. If you don't, the Clover boots on the drive with no update, and you have to repeat the whole thing. Just check that, and it will work (from the automatic system updates).
