For macOS Catalina, the site is changing our recommendations in regard to installing 3rd party kexts. We are changing the default location in MultiBeast from /Library/Extensions to /Volumes/EFI/EFI/CLOVER/kexts/Other.

Moving from macOS Mojave to macOS Catalina with an existing MultiBeast 11 for macOS Mojave installation. The following directions allow a user to manually remove kexts from /Library/Extensions and recache system on macOS Catalina.

1. Update to macOS Catalina using UniBeast 10
2. Run MultiBeast 12 to install all post-installation items​
3. Navigate to /Library/Extensions
4. If any 3rd party kexts exist, delete them*​
5. Open /Applications/Utilities/Terminal
6. Enter the following: sudo -s and type your password​
7. Enter the following: mount -uw /
8. Enter the following: touch /Library/Extensions /System/Library/Extensions
9. Enter the following: kextcache -i /
10. Reboot​

*Big list of 3rd party kexts that may have been installed to /Library/Extensions in macOS Mojave and can be removed after MultiBeast 12 for macOS Catalina has been run.

These are the kexts that MultiBeast 11 could have installed in /Library/Extensions:

AHCI_3rdParty_eSATA.kext
AHCI_3rdParty_SATA.kext
AHCI_Intel_Generic_SATA.kext
AppleALC.kext
AppleIGB.kext
AppleIntelE1000e.kext
AtherosE2200Ethernet.kext
FakePCIID_XHCIMux.kext
FakePCIID.kext
GenericUSBXHCI.kext
IntelMausiEthernet.kext
Lilu.kext
NullCPUPowerManagement.kext
RealtekRTL8111.kext
USBInjectAll.kext
VoodooHDA.kext
VoodooTSCSync.kext
WhateverGreen.kext

For reference, the default macOS Catalina /Library/Extensions from a clean installation:

ACS6x.kext
ArcMSR.kext
ATTOCelerityFC8.kext
ATTOExpressSASHBA2.kext
ATTOExpressSASRAID2.kext
CalDigitHDProDrv.kext
HighPointIOP.kext
HighPointRR.kext
PromiseSTEX.kext
SoftRAID.kext

I have written a shell script that will remove the MultiBeast installed kexts from /Library/Extensions.

Download and unzip the attached file. Then in Terminal cd to the directory that contains the unzipped file.

Usage example:

sudo ./Beast-Clean.sh "Test APFS"​

"Test APFS" is a test volume of mine. Replace with your volume name.

Also, it's pretty normal if you have:

- AppleMobileDevice.kext
- EnergyDriver.kext

The first one is used for connecting to iPhone, iPod or iPad devices, it's a system kext.
The other one is installed by Intel Power Gadget (if you use this utility to monitor your CPU)

Please correct me if I'm wrong.

I have the first one also. I can add AppleDataSetManagement.kext to the list (it is from and signed by Apple: I do not know what it is for).
 
What happens if I don't remove them but keep an additional copy in the efi other folder...???

soon you may not be able to have 3rd party kexts in /Library/Extensions

best to keep them in clover/kexts/other
 
Yikes, I could have used these instructions months ago...
Better late than never, this just fixed my borked install! ;D

Huge thank you for Multibeast 12.x
 
In a similar vein and I'm sorry if this has been asked elsewhere: Does the "300 Series Native NVRAM" option in Multibeast 12 remove the files installed via the emulated-nvram option in previous releases if present or does that need to be preformed manually first?
