No love on the 19.1. I can restart computer - no issue.
With Internal graphics ENABLED - I get caught in the "Begin Gfx Firmware load process" loop - no love.
With Internal graphics AUTO - I restart but still get a black screen on iPad.

Now if I turn of wifi - should I be able to connect to ipad wired? I get the error "To use Sidecar, turn on Wi-FI or connect over USB" - it is connected via a USB-C cable and I am able to click it in Airplay - just not get beyond that error message.

Thanks for the quick reply before - much appreciated.

Any thoughts?
@Eightball8 in the end I decided to switch to MacPro 1.1 to renounce to Sidecar but to have H264 and HVEC enabled on my Vega 56. For Sidecar I opted for the Duet Display program

It is a wise decision that allows you to have no limitations on other fronts too, I was in 1.1 on Mojave and it was optimal.
In any case, there would be more detail because on your hack it is that way with regard to H264 and HVEC.
I am in 19.1 with IGPU enabled (although I think I will do your same step, I have been thinking about it for a while) and I have always had this result with another video card too.

@Simon70 Very interesting! Are you practically in 19.1 IPGU enabled and VideoProc recognizes your graphics card for H264 and HVEC?
It would be interesting to see your EFI.
Why you think that is better 1.1? I have an i7 8700K and for my Hardware it should be better to use a 19.1 or 19.2 configuration....

Thanks!

Yes, it is as you said: 19.1 and IGPU enabled and the one in the image above is the result and has always been so, even when the video card was another. I am attaching the EFI that I currently use, cleaned up of the specific data for my PC, although I don't know how useful it can be, due to the difference in MB. I add that from the passage from 10.15.3 to 10.15.4 I have some problems with the Bootloader and with the sleep and I still try and look for help to understand and solve, but for what concerns the features we are talking about here, everything works.
With configuration 1.1 you have all the features (except Sidecar) of MacOS enabled on your hack, including the security ones, while with 19.1 or 18.3 (I have not tried others), some things do not go (for example the DRM on sites like Netflix or Prime), so it's always a bit of a compromise. With the solution you have chosen, by spending little money on Duet, you have bypassed that compromise.
I also thought that the most correct configuration was 18.3 with which I made the first installation of Mojave, but then reading and trying I found that 1.1 only brought advantages without disadvantages, on Mojave and then I went to that, then with Catalina , the story of the return to 19.1 is the one you read.

Happy Easter

confirmed, working with my main system, using OpenCore 5.7 and iPad Pro 2020.. probably would work with CLOVER too but I am moving on to OC these days where I can.

@Simon70 Thanks for your EFI.
I did some tests with your EFI but I never managed to enable acceleration with my graphics card in 19.2.
In your EFI (which is very similar to mine) there are voices that I had never seen enabled. For example, what is MATS in Drop Tables? In the GUI section you have "Legacy (First)"enabled. Why? Then you have FakeSMS_ACPISensors, FakeSMC_CPUSensor and FakeSMC_LPCSensors in the Kext-Other folder.......
I did some tests, however, between 19.2 and 1.1. I must say very interesting.
With Premiere (which is one of the programs I often use) Exporting an H264-encoded file with 19.2 took more than 7 minutes .... with 1.1 it took just over 5 minutes. Obviously the same file.
This made me realize that my way is 1.1.
Sometimes I have system crashes and I don't understand why.
OBS is one of the programs that crashes all the time :(
It would be nice to optimize it and make it stable.
Thanks for everything and happy Easter too late to you!

....

My learning process on Hackintosh does not start from far away, but only for a little over a year and I don't spend a lot of time in the hack, if things work.
Let's say that I started with the creation and configuration as a perfect ignorant, following one of the very well done guides found here on the forum and then until things went well I never studied Clover, the EFI and the config.plist .
Everything I learned was because I had to solve some problems or make some changes or updates in some steps, in which without changes I would not have been able to go on. For example when clover eliminated the 32 bit drivers ... or when I changed the video card and I had to look for a Kext sensor for the temperature of the radeon VII to add to the other SMC, etc...
My EFI in use (which has changed slightly since I posted it) is an EFI Frankenstein, the result of various assemblies and skimmings (to always be reduced to the bone, in fact I finally decided very recently to remove the patches for Mojave's USB since October I had to do it) of many EFI.
You will understand from yourself that many voices that have never given me problems have not yet awakened deepening "cravings", such as some of the questions you asked me.
For the SMCs that you asked me, I can tell you that they arrived at one of the many updates and they appeared after turning on some compars, it seems to me just about clover, but that now I do not remember exactly where.
In short, I always discover new things, these days to solve the problem of the crash after the sleep I had (and I solved it, hurray!) I learned something more about boot args and how to read and interact with panic reports and I took the opportunity to deepen the meaning of dart = 0 in my EFI from the first installation, imagine ... Every time I deepen something, in short, out of necessity, especially when I can not get help from those who are experts and much less effort to tell you what to do, making you struggle less too.
Obviously, as I receive a lot of help, I also try to give my little contribution where I can, such as what I said to you about the IGPU or SMBIOS 1.1 that I learned passing from Mojave to Catalina, through all the Beta, information that could perhaps be intergrate by those who know much more and above all in a much more organic way.
So excuse me if on some things I avoid answering you, not to tell you of the inaccuracies even worse than I already say.

Regards

Edit:
I'm here to update and give you credit for having aroused in me a curiosity that allowed me to solve the second of the problems that plagued me since the last update: the lack of selection and the boot disk by clover.
I changed that legacy first (which I had never looked to tell the truth, but that as soon as you reported it made me think that it made no sense in an UEFI system) in legacy last, to see the effect and on restarting everything worked as before.
Now I don't know why before it always worked correctly, despite being legacy first (I checked some old config.plis), but what matters is that it is solved. Now all that remains is to see if the automatic and correct selection of the disks will remain to the updates, as has always happened, until now, but I do not see why it should not happen, since a nonsense has only been eliminated.
So thank you!

@Simon70 I'm glad that I was somehow helpful. I am happy with the stability of my hMac. A couple of times it suddenly restarted. I'd like to solve that problem. Sooner or later!
By now I am stable with 1.1 and I don't think I will change soon.

Just last night I went from 19.1 to 1.1 too and I took Duet to compensate for the loss of Sidecar since I disabled the IGPU. I believe that in this period of seclusion it is more useful to have the DRM functioning and the computer more stable.
With little spending money I have not even lost the functionality of the secondary screen.
The only thing I investigated today, because it was too late last night, is that Duet works only via USB and to have it also in Wi-Fi you have to pay a monthly or annual subscription and the same thing applies to the functionality of Apple Pencil, that are not a negligible thing!:roll2:
In short, if you want to have the complete features that Sidecar offers you for free, you have to spend more than triple the cost of the app alone, every year.
Since Sidecar exists I have seen that I have not used it much for graphics so I can do without those functions (and when I need it intensely I will momentarily move to 19.1), so I can stay that way.
However, the limitations, without a subscription to Duet are not few if you put together with the NO Wi-Fi and the NO Apple Pencil (how mouse works) also the fact that there is not enough charging for the Ipad, when connected via USB.
On the other hand, it is gained that even the Iphone can become a secondary screen (as useful as it may be, in front of 4K monitors that today are at least 24 inches).

Unfortunately I still have a small problem with sleep and wake, of which I understand the cause and therefore I have the (manual) solution, but I still have not found the software solution.
In practice, the PC crashes on waking up only if there is an Iphone attached to a specific USB-C port (the only one of MB), so for now until I find the solution, before waking it up I disconnect the phone and I hang it up after waking up, it costs me zero, since I'm already at the PC, the problem will be when I get used to it and I have solved the problem, because out of habit I will continue in that way.
I've tried asking for help on how to troubleshoot, but haven't received any answers yet.
 
Based on results I've seen and testing, Sidecar requires an SMBIOS with an iGPU enabled. If it's an SMBIOS that has a T2 chip, sidecar will just have a black screen. I've heard that sidecar works on the hackintosh subreddit for iMacPro1,1 and MacPro7,1 but I haven't been able to get it to work. If someone figures it out I'm all ears :)

If you use the MacPro or iMacPro SMBIOS settings then you MUST have a discrete graphics card (GPU) to get Sidecar to work, i.e., not show a black screen on the iPad. This is because those machines use Xeon processors which do NOT have an iGPU and even though your CPU may actually have one the SMBIOS gets in the way. For example I built a hackintosh using a Core i7-8700k but did NOT use any kind of PCIe GPU. In my first setups I used the iMacPro setup but got black screens when using Sidecar. As soon as I changed to an SMBIOS that had an iMac definition then Sidecar started working. To ensure the easiest compatibility I used the Fenvi WiFi/BT card. I'm posting this in case somebody else is trying to figure this out.
