Hi guys, So, this little tutorial is meant to help people fix a new issue with Mojave: opening jpg files (looks like it happens with larger files, not so much with smaller ones) using Quick Look (on spacebar key pressed) or Preview app using the dedicated GPUs. The issue is that, when trying to open jpg files (for some reason, it doesn't occur with pngs), the pop-up window would remain in an endless loop. And from that point forward, any other app trying to open the same file, will either become unresponsive (in the case of the Preview app) or just stay in endless loop (in case of Quick Look) As a workaround, in case the tutorial below doesn't work for you, you can use Grab (built-in app in MacOS) to open said files. This issues DOES NOT occur using the iGPU. So.if you're comfortable using the iGPU, just switch to that and you should be good to go. You don't need this tutorial.
This tutorial is based on @Cyberdevs' research and testing on this topic (especially useful if you're using an RX series AMD video card), and my own very limited time testing this on my rig. I just thought it would be useful to create a new thread for it so that people can discuss this particular issue here. With that being said, I'll just move on to the actual tutorial. New (probably better) method. Switch your SMBIOS in Clover config in regards to the dedicated GPU you're using, instead of the CPU. Take a look here and choose the corresponding SMBIOS closest to your hardware. Yeah, that's it. In case you lose CPU PM with this method, there are multiple ways to fix that, and they do not make the object of this thread.
It worked perfectly fine for me though and I didn't need to change anything else. Alternatively, you can also try one of the MacPro SMBIOSes, such as MacPro5,1 or MacPro6,1. It was tested multiple times and it showed good results. Keep in mind that choosing these will most likely not display you an iGPU in System Report, since those machines generally (probably all of them) use Xeon CPUs with no iGPUs either. A simple Lilu plugin Thanks to vulgo for the plugin and @Matgen84 for sharing and testing it, we now have yet another possible solution to this issue. It's a Lilu plugin (which means that it requires Lilu.kext in order to work) it's called NoVPAJpeg, and it can be downloaded from here. You use it as a regular kext, alongside Lilu.
I prefer (and recommend) using it within the EFI folder, in Clover/kexts/Other. But if you want to use it in S/L/E, that should work just fine.

More info can be found in this post here. In case you wanna try alternative medicine. The main thing we need to do is actually very simple: we need to enable the iGPU (integrated GPU) by default, in BIOS, while actually being connected to the dedicated GPU. For ATI GPUs (curtesy of @Cyberdevs' post here). The discreet GPU should be set as primary in BIOS and your displays should be connected to your discreet GPU The iGD/iGPU/iGFX must be enabled in BIOS/UEFI as the secondary GPU. I removed the DSDT Reconfigured the config.plist to and removed some flags which weren't needed because of the DSDT added the InjectATI + Ornioco Framebuffer (I removed the Orinoco framebuffer because of some weird glitches but it might be useful for other AMD GPUs if you inject the correct framebuffer according to your GPU.
First post, thank you all for any help offered. I am coming from a certain commercialized hackintosh community - after seeing such amazing vanilla installs and reading of the talent here, I decided to have a go at not using such software methods. And I immediately got myself into a predicament BACKSTORY I successfully upgraded from Mavericks to Mojave 10.14.2 but decided to start over and do a clean install because my Vega Frontier was not playing OOB even with Lilu & whatevergreen - and there was a lot of 'code junk' Clover barfed at boot from this 'commercialized software'. SUCCESS I created Mojave USB installer from scratch using the latest Clover, it worked fine, got me to the Mojave install screen. PROBLEM For reasons unknown to me, I decided for one last ditch effort to see if I could get my already installed Mojave playing nicer - instead of starting over clean.

So I installed the latest Clover on my Mojave SSD, (it had a Clover version YEARS ago when I last installed Mavericks) and I replaced the EFI file with the kexts and config of my USB EFI file because I figured, since the USB installer launched, it was all good to go. Now nothing boots after BIOS. Not my Mavericks drive, Mojave SSD, nor my USB Mojave Installer. They all hang right where Clover usually launches. I look at my USB lights and nothing flashes. The only drive I can use is Windows 8.1 (my testing environment) and not from Clover. That's just booting windows up without any HD's plugged in.
Is there a way to rescue my predicament? I don't have another Mac computer and CloverConfig only runs on Mac. Is there a way to fix the USB from Windows? Specs: Gigabyte GA-X58A-UD5 rev. 2.0, FC BIOS, i7-980x, Vega64 Frontier Edition, Nvidia GTX480, 24 GB 1333 RAM, SSD + various hardrives.

The kernel’s command-line parameters The following is a consolidated list of the kernel parameters as implemented by the setup, coreparam and moduleparam macros and sorted into English Dictionary order (defined as ignoring all punctuation and sorting digits before letters in a case insensitive manner), and with descriptions where known. The kernel parses parameters from the kernel command line up to “–”; if it doesn’t recognize a parameter and it doesn’t contain a ‘.’, the parameter gets passed to init: parameters with ‘=’ go into init’s environment, others are passed as command line arguments to init. Everything after “–” is passed as an argument to init. Module parameters can be specified in two ways: via the kernel command line with a module name prefix, or via modprobe, e.g.
