# Clover Kexts and Firmware driver conversion(.kext, .efi)

Main thing to note is that you must specify your kexts and firmware drivers in your config.plist, or else they will not load. All kexts that are currently supported on Clover will work on OpenCore, however many have been deprecated with better variants being integrated into OpenCore. Firmware drivers are a bit different as they can in-fact break booting.

# Kexts

For the most part, all kexts are supported in OpenCore. However there are a few integrated

Integrated Kexts:

  • NullCPUPowerManagement.kext
    • Integrated into DummyPowerManagement under Kernel -> Emulate
  • BT4LEContinuityFixup.kext
    • Integrated into ExtendBTFeatureFlags under Kernel -> Quirks

# AptioMemoryFix Note

Well before we actually get started on converting the Clover config, we must first talk about converting from AptioMemoryFix. The main thing to note is that it's inside of OpenCore with OpenRuntime being an extension, this means that AptioMemoryFix and that there's also a lot more settings to choose from. Please see the hardware specific sections of the OpenCore guide to know what Booter settings your system may require(HEDT like X99 and X299 should look to the closest CPU like Skylake-X should refer to Skylake guide and read the comments as they mention specifics for your system).
