I would think it should. I have had audio working on various cards that I had passed to MacOS. Have you tried adding the Voodoo HDA kext? I have used it on hackintosh installs in the past and I believe I had even used it within Unraid for a little while when using an Nvidia card. I also recall something about Nvidia audio drivers, but don't remember the details. Voodoo HDA should work if nothing else will. Just add it to your Clover config.

That's probably a pretty good guess. I would research if that Intel chipset will work with MacOS or not though. If you find that it doesn't, you can always get an addon ASMedia card for $30 or so and pass that through instead. There were a few people having problems passing through USB controllers in the past. One of the problem ones was a Fresco I think. Don't know about Intel, unless the Intel controller uses another chipset for the actual USB controller.

From the Unraid control panel, go to Tools and then select system devices. You'll likely have more than 1 USB controller, but you can't pass the controller that your Unraid USB key is plugged into. I ended up have 3 on my board. 2 controllers the ports on the back panel and front panel header and then there was another USB header plug on the board that was on a 3rd controller. I don't recall immediately, but there is a way to show which controller the USB key is connected to by using the command line with a command. I think Space Invader One has a video about USB controller pass through.

Based on 1812's posts, you should have no problems with the GT730 and Mojave. I had other Nvidia cards working with High Sierra in the past and they worked great, right up to the point where I went to dual screens. Then problems started. I broke down and bought a 580x Radeon card for my Mac VM and have a Nvidia 1080 ti for the Windows VM. This is my daily machine and I use both OSes interchangably all the time and push both of them to the limits, sometimes both at once. I'm running a 10 core i9 7900x. Your quad core should be fine with 4 vCPUs to each vm and split the ram, being sure to leave 1 or 2 gb for unraid to use. As far as USB pass through, you'll need to determine how many USB controllers you have on your motherboard and will need to pass an entire controller to a vm if you want to plug and unplug USB devices in both operating systems. If one system will only have fixed devices, say a keyboard, mouse and a sound device, you can pass through the individual USB devices to the VM instead of the controller. ASMedia USB controllers seem to work great in MacOS. I don't remember the chipset I have, but I've passed a bunch of them through without problems. A few of us were discussing USB chipsets and controllers a ways back in this thread.

In order to have both operating systems booted and running at the same time, you need to have a GPU for each one. If the iGPU works for Windows and you've ordered a GTX710 for Mojave, you can potentially run both at once if you have enough other resources in the system. I built a machine specifically for running both OSes at once over a year ago that I am using today and love it. Everything depends on the total resources of the machine and what you are trying to do with each operating system. Running both at once gets into passing USB controllers and such so that you can have a keyboard and mouse for each system. If you're looking to do that there's help here for you. If you can get by with only 1 system running at a time, you should be all set.

Sorry, forgot to mention the copying of the EFI folder to the cloned drive. Also, resizing APFS rom within High Sierra is not difficult if you use the GUI Disk Utility. If there is more space on the partition, or in this instance the virtual image, select the partition and enlarge it or set to maximum size. I don't remember the exact terms for everything, but it's really simple. The part that I don't know how to do is resize a VM image in unraid. I know there has to be a way to do it and it's probably not that hard, but why risk messing up your working image of MacOS to resize it if you have the space to make a new image that is larger. Steve, what is device 0000:00:1f.3 on your system? Do you have devices passed through like a mouse or keyboard? On occasion I have had issues with passed through mice. I have had better luck passing through a USB controller and plugging the mouse into that instead. Or could it be a device that doesn't exist any more and being that you have a manually edited XML file it won't be removed automatically.

I would recommend try without specifying the CPU topology. Find the line in your config file that look like this: <topology sockets='1' cores='2' threads='1'/> And remove it completely. The VM will load without a topology specified as has been confirmed a few times. Optionally, if the above line is how your topology is specified, you could also try it with 1 core and 2 threads, but I really recommend no topology based on 2 cores only. Your experience with NVidia and dual monitors is the same as everyone elses. I am glad to here you got it to boot though. I never did have any success with display ports options on my GTX 960. Did you actually get the image file to expand in size? You could just create a new 100GB image as a 2nd drive, use Carbon Copy Cloner or similar to clone the system disk to it, then use startup disk selector in System Preferences to specify the newly created disk. Once confirming that it boots from the newly imaged (larger) disk, shutdown the VM and remove the configuration for the Primary disk. I have done this to switch between imaged disks and physical passthrough disks on High Sierra VMs or to swap out the physical disk on a VM.

That's exactly the problem that I was having with my NVidia GTX 960. If both display were connected, it would always kill both displays to solid black. Common problem from what I have read in the hackintosh community. I tried Lilu and NVidiaFixup, unfortunately that didn't solve the problem either. My cards don't have 2 DVI ports though, so I was unable to try that. Mine was a combination of DVI and HDMI or HDMI and Display port or DVI and display port. The display port options never worked right, even with 2 of them. If you got yours working with dual DVI, then awesome and congratulations. Between the boot up with 2 displays not working and the other oddity's I frequently had, I chose to turn to the dark side and go AMD. Haven't had a non-NVidia card in over 25 years. lol

No, it's not the SMBIOS in gridrunners video. Isn't that a standard, iMac 4,1 or something? 4,1 is old, maybe it was a later one. Don't remember. The only advantage that I know of would be support for new devices and CPUs. I haven't tweaked my CPU settings yet, but this install started out as a bare metal install on the same hardware, following a howto on InsanelyMac. My motherboard has an x299 chipset and I have an i9-7800x CPU. For the bare metal hackintosh install to work correctly and be able to correctly identify the CPU and also handle CPU turbo and clock settings from within High Sierra, there needed to be specific kexts and the iMac Pro SMBIOS. From that install, I only added the dsdt for QEMU that gridrunner supplies to Clover. Everything else stayed the same as my bare metal install. I'm glad to hear Apple supports the 480 too. Have you tried the voodoo kext to see if you can get hdmi audio working if you wanted it? I know it showed 6 audio outputs for this 580 card.

I can't speak for the 480, but I did finally breakdown and buy a Radeon RX580. Plug 'n Play, no problems whatsoever. Boots with 2 monitors connected, can resize either or both with no flicker or problems. No blanking at any time. I should have done this from the start and saved myself all the futzing around for the last 4 months, but I had 2 extra GTX 960's and thought I could get them to work. For the record, I'm also running an iMac Pro 1,1 SMBIOS. My System is running very very smooth. I added another little item to help performance of High Sierra and Win10 too. I picked up a Dell Perc H310, but left it with the default firmware on it. I'm running 2 separate Raid0 arrays with SSDs. 1 is passed to High Sierra and 1 is passed to Win10. Man they both fly like that. I always used to run Raid0 on bare metal machines for the extra performance with SSDs and then use a decent backup plan. The Raid card allows me to do that with my 2 vms and then I use the normal, mechanical drives for the unraid shares and the 2 onboard M.2 drives for cache. I'm feeling pretty good about this build now.

1812, would you be willing to try something out that I just found in a thread on tonymacx86? A guy over there, jgalt184, was having trouble with multiple displays on an NVidia graphics card in his hackintosh and could not get it to boot. He ended up adding NvidiaWeb=YES to the bootflag in the config.plist for Clover and says it started working. I have to assume that a bare metal hackintosh is having the same problems that we are with a vm inside Unraid. Unfortunately, I had given up on my dual display system and have been using my Mackbook Pro for my main Mac desktop again and reconfigure my Unraid desktop for now so I don't have a MacOS VM running at the moment to test on.

That's exactly the same problem I had. Being unable to boot with 2 displays connected to 1 card, I tried 2 cards with 1 display each. It loads to the logins screen, then when entering password, it starts to load and then jumps back to the login screen again. If I boot with only 1 display connected to 1 card, login and then connect the 2nd display, it dumps back to the login screen again.

Schlichi, I'm glad you got the 960 card working and are happy with the performance. The 960 does everything I need in OSX and works pretty decent in Windows on games at 1080p with medium to high settings, depending on the game. All, I did find out something interesting today with my OSX vm that I'd like to see if anyone else can confirm similar results. I have all my CPU pinning configured to allow my Mac VM 4 hyper threaded cores, my Win10 vm 4 hyper threaded cores and there are 2 leftover on this 10 core i9 for another vm (runs some backup tasks and an internal DNS server) and unraid. I was looking at the Dashboard in the unraid gui and saw that the first 6 cores between unraid, the odd vm and Windows were all using the hyperthreads pretty evenly. Not dead even as expected, but the load was pretty even across everything when there are processes running in each vm for the cores it's using. On my High Sierra vm though, only half were being consistent and the hyperthreads were barely showing any load on them at all. After seeing this, I tried changing the setting to 8 cores and 1 thread each. There was a definite performance improvement in High Sierra and now the they are all utilized fairly even. I have to assume this has something to do with Unraid as I would think Apple has their use of hyper threads optimized, right?

I have a Sonnet card with the FL1100 chipset in my unraid server. This particular one is about 4 years old and only shows up as 1 controller to pass through. I do not have a Supermicro motherboard though so it does not affect me at all. Everything works as it should. All the other USB controllers on my system are ASMedia. The builtin controllers on the motherboard will passthrough just fine and work as expected and then I have an addon PCI-e card that's an ASMedia chipset too for an additional USB-C port. This card works great in either Windows or OSX. I would have assume based on your testing that any of the FL1100 chipsets are going to cause you problems with the Supermicro board. Being that you've tried everything else, ASMedia seems to be the path you'll have to try.
