macOS 10.15 Catalina is Now Available on the Mac App Store

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.)

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?

Apparently the problem goes far beyond updating Clover. I have an RX 470 and that problem was present in clover 4920, but after updating it, the problem disappeared. In fact, if I change my Efi folder back to the one with Clover 4920, the problem returns. That's why I had that conclusion.

I think I will wait 6 months until I update, like I did with Mojave. Luckily we will get security updates for Mojave until 2021, so no need to hurry here. Catalina does not seem to have any must-have-features anyway.

My 10.15 has been installed, but geekbench 5 runs very low

I upgraded from 10.14 to catalina, this appears on my screen. Anyone know how to solve? Using i7 5820k, dual rx580.

The direct upgrade from Mojave to Catalina went great for me as well.

And Catalina works on my GT710

Here's a drive icon workaround. Boot your system from a Mojave drive and change the drive icons (both system and data) via the old method of copy and paste. Once done reboot your system back to Catalina and the icons will stick.

10.15.1 beta solved the issue. icons can be changed as in the past

 

[Asjas]

Yeah for sure

Try it with SSDT-EC.aml in /EFI/CLOVER/ACPI/patched.

This was all I had to do to get past the issue on my HP EliteBook 8470p. Everything seems working now except Bluetooth.

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.

CodeDJ, are you using VirtualSMC instead of FakeSMC ?

I tried switching a while back but had some issues so went back to Fake.

What efis/kexts are you using ?

I want to give another go, but this time on a fresh ssd
