10/08/2019 Clover 5070, 10.14.6 Supplemental Update & Attempted Catalina Upgrade
The last addressed first: failed with prohibited symbol, still watching for a fix.
Clover 5070
This was a scary update. Why scary? Well, getting to the EFI partition to change things is a little rough, and, not knowing what may break is another. However, this process was made MUCH easier as a result of this excellent
"How To" thread. The short of it is, Clover changed some structure, dropped some drivers, and that made things a little trickier.
Here is the short process:
1. Backup your system using your favorite tool, such as Carbon Copy Cloner.
2. Update Clover Configurator, "CC".
3. Using CC, or your favorite updating tool, update your kexts, or, if you prefer, make sure you have located the current kexts and copy them over manually to the proper places. I had to update Lilu, Whatevergreen, and AppleALC.
4. Copy your EFI folder to <your system drive>/EFI-Backups/<your chosen backup folder name> - so you can find this later as you'll need to do some copying.
5. Drag the CLOVER folder in your mounted EFI driver to the trash and empty the trash.
6. Using CC, download and *begin* the install process for the latest Clover.
7. When you get to Installation, click Customize.
8. Have your Finder view set to your EFI-Backups/../Clover folder and begin to match up your drivers to what's in the installer (refer to the thread previously linked) using your Finder view as the reference.
9. After matching everything, run the installation.
10. After installation, now you'll need to copy over the ACPI->Patched files, config.plist, Kexts->Other files, driver64UEFI files (to the drivers/UEFI folder in the new version) that are missing/needed, and your theme information.
Once that is done, you should be good to go for a reboot (after double-checking everything to ensure nothing is missing) and get back into MacOS.
10.14.6 Supplemental Update
I thought I had done this, but, apparently not. After updating Clover & kexts as above, this update proceeded without issue. Safari also updated at the same time. It did take a little while.
