The update went fine for me but I lost sound which appears to be fairly common.
Resolved by downloading the latest ALC and Lilu kexts from ‘Downloads > Kexts’ and placing them on the desktop. Then I installed them using Kextbeast which you can get from ‘Downloads>tonymac downloads’. This resolved the issue for me and may work for you.
For info, I use onboard sound connected to external speakers so it may require additional work for those using sound from their monitor.

Thank you for your response. It helped me to get my audio working. :headbang:

Clover v5070 -- same as with Mojave pre-update. I tried to change as little as possible.

Graphics shows "Radeon RX 470/570 4 GB", although I am not noticing defects (maybe text isn't so sharp as it was)?

Sleep/wake and shutdown problems persist with USB keyboard/mouse. I use a KVM switch -- will pull that to see if things change.

Time Machine problem appears to be happening on real Macs too.

iTunes/Music issue involves adding server files to library -- didn't care before. Still buggy -- beachball.
I get it. In my case I do not have problems that I have not solved already, but a slight one, with the graphics, since the gradients and shadows are not rendered correctly, especially in the areas that have the effect of blur.

Hello, what is achieved by applying that flag?

with those flags you could be able to boot right , so be careful and check your BIOS is right date and time. some times date and time get discontrolled at installing process and its a reason because installer don't complete task after first reboot or restart.

It's not Clover issue. It's UEFI drivers outdated.

Basically remove:

AppleImageCodec.efi
AppleImageLoader.efi
AppleKeyAggregator.efi
AppleUITheme.efi
AptioInputFix.efi
Ps2MouseDxe.efi
FirmwareVolume.efi
SMCHelper.efi

And add:

AppleGenericInput.efi
AppleUiSupport.efi
VirtualSmc.efi

Of course, replace FakeSMC kexts with VirtualSMC kexts.

I wasn't able to boot with Clover with FileVault so have been using OC but gave this a try and that was the fix - wow! thanks. I had to disable SIP to be able to install the latest Clover on Catalina.

Clover boot handles HiDPI. I tried various options of OC but never got HiDPI working.

Before your suggestion, I was getting stuck on the Apple Logo screen forever. Never got to the point like other people where there was a delay of 2-5 minutes.

After following your suggestion, I no longer get stuck on the Apple Logo screen, in fact it boots at the same speed as it used to on Mojave.

Glad to hear it.

Just updated to the 5096 but still have the lines
I had read somewhere on these forums that the purple lines are a side effect of having an AMD GPU. I get the purple lines as well (still on 10.14.6 at the moment) and I have an RX 560. Do you happen to have an AMD card in your hack?

Success!

Preparation:

Finally sat down and prepared a USB DSDT (guide) and made sure that the USB ports I had setup were working properly. Removed the 4 Mojave USB kexts.


Updated Clover to 5097 and updated the drivers I used from Mojave in Clover Configuartor. The one I couldn't find in the newer clover was XhciDxe-64.efi. After some reading I decided I'd go ahead without it and see if it was still used after the USB DSDT. (So far I've not seen any change in not using it, USB3 still worked in Mojave and Catalina.)

Ran a Carbon Copy backup of my Mojave drive with updated Clover EFI drive.
-Booted from my backup and made sure all was ok.

Set my Clover Timeout to 15 seconds to give me a window to catch the Install boot drive.

Update:

Download approx 1 hr.

Install approx 45m.
2- Reboots in the first 15 minutes. 1-reboot in the last 20 minutes.

Logged in without a problem.

Check:

Verified in IOreg that my USB ports were still according to my DSDT.
Checked audio on HDMI, all good. Checked through my RME audio interface, all good. Device Handoff works fine.

Didn't check: Facetime or Messages (I'll have to wait for people I know to wake up.)
