Thanks for all the help. Last thing before I start attempting this later this week - Are you HFS+ or APFS formatted ?

 

APFS. Good luck.

Hey guys,

 

could someone have a look at my config / Clover folder? I have a very basic configuration which worked really nicely with High Sierra, I did an upgrade to Mojave without any issues. Ethernet works, Sound works and my system is pretty stable as far as I can tell. However, I cannot manage to upgrade to Catalina. I get stuck around the point shown in the image, sometimes I get a tiny bit further depending on the boot flags. Without the RTC-Fix I'm getting stuck at pci configuration. Graphics card is a MSI GT 710 low profile, so there's native support. I'm running on a 14,2 iMac SMBIOS.

 

Thank you!

 

Edit: I experimented a bit more with a separate installer so I wouldn't mess up my system. I reverted back to iMac 12,2 and took out RTC fix, applied HPET fix and FixHeaders. Sometimes it went further and eventually did get stuck right at IOConsoleUsers. Other times it would just get stuck mid-line around the stage I posted yesterday while using the same configuration. Any ideas?

as I need to purchase a GPU , do you suggest gt 710 1gb or 2gb ? Or other models ? (something budget)

 

Look for a GT 710 with 1GB GDDR5 memory.

If you research some compatible AMD models for hackintosh, look at benchmarks before you buy.

ok, will try 1 or 2GB version. Do you know if there's hope for the Internal Speaker to work ?

 

Since now I'll probably get back on this in few weeks, do you suggest moving to Catalina or stay on Mojave ? It would be nice to get an updated guide starting a new thread for this machine,

If you install all based on this guide will probably work every part of your hardware, and you will probably use layout 15 to your AppleALC patch. So, if you want to use internal speaker you will need to inject layout 13. Theres no way to use they both without DSDT editing (if I am not wrong).

 

Move to Catalina, theres no great differences but mandatory APFS format.

If you are trying to use Core2Quad you will need to delete the file (or replace by the attached bellow):

System/Library/UserEventPlugins/com.apple.telemetry.plugin

With this file, you will got a KP. You probably will have to research some terminal command to do this in the terminal in the recovery boot or have to attach your drive to another Mac machine working with APFS R/W support.

Good hack.

Someone here have an Optiplex 780 MT and native Audio working within Catalina?

I have 2 partitions (one with Mojave and another with Catalina).

Oddly, my setup with AppleALC and LayoutID 13 or 11 + Lilu works with Mojave flawlessly but dont with Catalina 10.15.3.

Any ideas?

That's the wrong folder. I need your Clover folder.

And indeed what polyzargone says. Since it's still showing the 5450 I suspect that you have two Clover installations (probably one on / and one in the ESP) and one of them is overwriting the other.

Hey this is me again I boot onto my hdd fine but when I take out my usb I get the prohibited sign

Hi folks, 

  I was dumping old hardware when I decided to try build Catalina on the dell 755 Mt again. I managed to get everything working with one slight issue. When watching media on youtube in a 1080p format in safari the sound becomes very crackly and distorted. I am using the latest voodooHDA kext. When troubleshooting I noticed that when I changed the audio output quality in Applications/Utilities/Audio Midi Setup to the lowest setting of 8 Channel 16 bit integer(32.0 Khz) outputting through the HDMI the sound quality increases dramatically but still with a very slight distortion if listening on a high volume. I have tested same with activity monitor open to see if it might me too much load on the CPU but this is barely hitting 20% usage when viewing videos in youtube. I also tried using a different browser such as chrome and while the distortion is not as bad, it is still annoying. I tried the same hardware in High Sierra & Mojave with the very same results. I have also tried using the applehda.kext method from ElCap with the same results. I have my CLOVER.zip attached and my hardware profile is in my signature.  has anyone experienced any issue like this and any help or recommendations would be appreciated. I tested the same hardware with windows and there is no issue.

      Hi,
       
      I'm rather new to Hackintosh and trying my first build with OpenCore on AMD, but I run into issues causing OpenCore to crash before even loading the macOS installer. As I'm not sure which one is causing the crash, I'm trying to resolve all of them and one of the error messages has to do with WhateverGreen, which I was able to see in this slow-mo loading video. Basically I'm getting an error that I'm running an unsupported processor, even though I think I was following this guide by the step.
      What could be causing this and what do I need to do to resolve it?
       
      CPU: AMD Ryzen 2700X
      MB: Gigabyte Aorus X470 Ultra Gaming

      Hi team,
       
      I'm looking for the best route to achieve this upgrade, so I have been stuck with HS since Nvidia drivers stopped being supported on newer MacOS releases. Now I'm having an AMD 5700 xt on the way and want to plan the upgrade properly. I have added some information below and questions that might help with your recommendation.
       
      Current GPU 1080 ti with Nvidia webdrivers installed. So should I uninstall the webdriver before adding the new GPU? Clover is being used and EFI attached. Any kext must be removed? or parameters adjusted MacOS HS 10.13.6, should I upgrade before using the new GPU? CPU: 9900K Motherboard:ROG MAXIMUS XI HERO (WI-FI) Dual Monitors I have a Time machine backup, Do you recommend a fresh install? and If I did, will I be able to restore my data/apps as-is?  
      Please let yourself free to explore further aspects to considers.

      Hello,
      1st my laptop spec. 
      CPU - 2.53 GHz Intel Core i3 380m
      RAM - 6 GB 1333 MHz DDR3
      GPU -  1st gen Intel HD Graphics 288 MB
      Laptop - Dell Vostro 3500 series
      BT/WIFI - AzureWave BCM94352HMB
       
      I installed Olarila Mojave 10.14.6 and managed to install 1st gen intel HD graphics but it was bit laggy bcos this gnu doest support metal and its a old machine, so I decided to move to Olarila High Sierra.
      I installed it with most of things working fine expect some issues, for that I want to make SSDT and DSDT to make it run without glitches.
       
      I am atteching my sendme.zip , can some take a look to my current settings and suggest me some changes  
      (Olarila down from few days for me )
