2. Mount your ESP.

For Clover:
If you're using Clover, copy the kext to EFI/Clover/Kext/Others

For OpenCore:
If you're using OpenCore, copy the kext to EFI/OC/Kexts. You'll also need to add the kext entry in the Kernel section of your config.plist.

STEP 2: Restart your System


After performing all the above steps, restart your system for the applied changes to take effect.
