Just a quick post to share how to install Clover and other stuff to a 10.15 Catalina drive. The root partition is read-only by default. To make it read/write, use the following steps.

1. Open /Applications/Utilities/Terminal

2. Make the root partition read/write by entering the following:
Code:
sudo mount -uw /

3. Enter your password and hit return.

You will now be able to install Clover, use MultiBeast 11 (Mojave version) for Post-Installation, and install kexts. Be aware that when the system reboots, the command must be entered again. The final Catalina version of MultiBeast will do this automatically.

How do we now check/repair the drive when booting in Single User mode? The pre-Catalina fsck -fy command no longer works (mount -uw / is what's currently entered AFTER completing a disk check).

For those looking for a non-terminal one-click solution you can also use Hackintool :-

You can use the to icons to the right to install kexts to /L/E and manually rebuild kext cache if required.
See the kext guide for more info on installing kexts to /L/E in Catalina ...

Cheers
