I would like to ask for some advice or help even.
I have had some usability issues in the past with my hackintosh so I installed Mojave for the second time but it keeps producing the same exact problem. Most of the time the system stutters and lags after login. The app icons just bounce if I want to open them and even if it does it takes forever. Another thing I picked up on is that it seems like there’s no internet access whenever this occurs. The problem ceases after like 2-3 restarts and everything is back to normal.
What could cause an issue like this? I had the same thing happening with my previous install but I thought that was because of unnecessary kexts I left in the EFI. I only have the bare minimum required this time so I’m kinda lost.
Mobo: Gigabyte B360M D3H
Graphics: Radeon Vega 64 8OC
CPU: Intel i7 8700k
Ram: 32 Gig
SSD: Samsung Evo 860 250gb
I also have a separate HDD with Windows 10 installed for gaming purposes. I would greatly appreciate any kind of help, thanks in advance!
I’m an happy user of a x99 built hackintosch since 6/7 years using it mainly for photoshop and fcpx . Using new camera with better resolution and video in ProResRaw , my built start to struggle a bit
I’m thinking of making a new built and seeking for advices for this new built that I want evolutive and last at least as long as my previous built
I’ll use a SSD M2 forth Generation so I need at least 2 to 3 SSD M2 PCI x4 slots
then which proc to use , I was thinking about the AMD Ryzen 9 3900xt or the Intel I9 10900k ( don’t have the money for AMD threadripper ) if you have better idea I’m really open to it as long as you explain it to me
then which chipset should I use:
for Intel , should I go to Z490 or X299 or W480
For AMD , I think I have only the choice of X570
I always used Gigabyte motherboard so it will be naturally my first choice but again I’m open to any suggestion
I need at least usb 3,1 Gen 2 and TB3 is not necessary but an option and can be add later on with a PCI Card I think
So I’ll be pleased o read your opinion and the choices that you’ll do for the purpose of this built
thanks in advance
I recently built my 1st ryzentosh.
I also used Opencore (0.6.1) for the 1st time and followed the install guides on Dortania.
Now I need to map my USB ports and apparently it’s not achieved the same way on AMD platforms compared to what I was «used to» on Intel platforms.
The guide on Dortania is a bit confusing to me since there is information that is not clearly labelled as «for Intel» or «for AMD» and I thus don’t understand very well what I should and shouldn’t do.
Can anyone give me advice or point towards as comprehensive tutorial intended for AMD-based builds.
Thank you very much in advance for your help.
Hi everybody. I’m stuck here and after a few days I’m really not able to boot.
My setup is the following:
CPU AMD Ryzen 9 3900x
GPU Aorus RX 5700 XT
MOTHERBOARD AsRock x570m Pro4
SSD 1 Corsair MP600 1TB
SSD 2 Gigabyte Aorus NVMe 1TB
RAM Crucial Ballistix 2x32GB
WIFI BCM94360CD
Error message from Bios attached to this thread.
Thanks to anyone willing to help me. I’ve tried different open core versions, adding and removing a lot of kexts, keeping essentials ACPIs, setting as true or false different .plist settings that I saw resolving similar issues as mine but nothing seems to work.

I managed to install Mojave on my MSI GP62-6QE laptop with somewhat success. The only annoying thing left is that everytime I shut it down it seemingly kernel panics and I get the «Your computer has restarted because of a problem» at startup.
I tried many different things such as removing emuvariablesuefi64, checking FixShutdown in CloverConfig but it seems the NVRAM is causing this issue.
Mac os radeon 7750
Apple added support for the 7000 series of AMD Radeon HD graphics cards last week, in version 10.8.3 of OS X Mountain Lion. Prior to this, 7000-series graphics cards did not work properly in Mac OS X; while you could still boot a Hackintosh with these cards, you couldn’t view your computer screen in full resolution or run any applications that required graphics acceleration. With this new support in Mac OS X, however, 7000-series graphics cards have finally become a practical option for your Hackintosh.
Don’t like this method? Check out tonymacx86’s alternative EFI partition method.
LATEST UPDATE (January 6, 2013): This method also works with newly-released Radeon R9 270, 270X, and 280X, all of which are really just rebranded 7000-series models.
Computer Requirements
Graphics cards in the AMD Radeon HD 7000 series can now display Mac OS X at full resolution with graphics acceleration. That being said, graphics support for the 7000 series still isn’t perfect. For starters, Chameleon and Chimera bootloader don’t support booting Mac OS X with these graphics cards, which use larger video BIOSes than previous generations of cards. As a result, you have to rely on your computer’s integrated graphics card card to boot your computer (more on that later). Here are the full requirements for enabling 7000-series support:
- A Hackintosh running OS X 10.8.3: Only version 10.8.3 of Mountain Lion (and newer) includes the new graphics drivers for the AMD Radeon HD 7000 series, so you will have to update your Hackintosh.
- AMD Radeon HD 7000-series card: Currently, most desktop graphics cards in the 7000 series are supported. As of March 24, 2013, the AMD Radeon HD 7970, 7950, 7870, 7770, and 7750 have been confirmed to work without the need for additional drivers. The AMD Radeon HD 7850 only works with specially edited kext files. Check out this forum thread for a list of specific graphics card models that have been confirmed to work.
- Integrated graphics card: You will have to set your integrated graphics card (located on your computer processor) as the primary graphics card. Most desktop processors include integrated graphics, though there are a few rare exceptions. Nowadays, all new motherboards include support for integrated graphics cards, but older motherboards using chipsets like P67 and P55 don’t work (e.g. the Gigabyte GA-P67A-D3-B3 or GA-P55-UD3). Alternatively, if you own a second graphics card that works with Mac OS X, you can add it to your computer and set it as the primary graphics card instead.
If you do not have an integrated graphics card or second graphics card available, this guide will not work. Instead, you will have to follow this alternative guide to installing your bootloader on an EFI partition.
1. Set your integrated graphics card as the primary graphics device
Since Chimera and Chameleon bootloader don’t work with 7000-series graphics cards yet, you’ll have to go to the BIOS of your motherboard and set your integrated graphics card as the primary graphics card instead. This way, Chimera/Chameleon can rely on your integrated graphics card to start Mac OS X.
Boot your computer, and enter the BIOS. To enter the BIOS on a Gigabyte motherboard, you have to press the delete key when it boots (before the operating system starts). Different manufacturers set different keys for opening the BIOS.
On the newest Gigabyte motherboards that use the UEFI standard for their BIOS, you need to set «Init Display First» as «IGFX» (which stands for integrated graphics), and set «Internal Graphics» as «Disabled».
On older Gigabyte motherboards, set «Init Display First» as «Onboard». On motherboards from other brands, this setting will be called something similar, such as «Primary Display».
2. Plug your monitor into your 7000-series card
This part is self-explanatory. Connect your computer monitor to your 7000-series graphics card. This way, your monitors will use your 7000-series card in Mac OS X, even though you set your integrated graphics card as the primary graphics card in the previous step.
From now on, your computer to boot with a black screen. Basically, you won’t be able to see anything on your computer screen until Mac OS X actually starts (once Mac OS X starts, everything will work as normal). Your computer is using your integrated graphics card card to run the boot process, but your monitors are connected to your 7000-series card, so the screen is blank.
3. Boot your Hackintosh
Once you’ve set up your BIOS, reboot your computer. Wait for Mac OS X to boot; your screen will be black for a while. Of course, if you do not have Chimera bootloader set to automatically boot Mac OS X, you will have to press the «Enter» key to start the boot process. If Mac OS X does not boot within a few minutes, you may have to enter the boot flag «GraphicsEnabler=No» (without quotation marks). You won’t be able to see what you’re typing, but the normal method for entering boot flags will still work.
Eventually, Mac OS X will start. If you reach the desktop, congratulations— you’re done!
NOTE 1: If you reach a white screen instead of the Mac OS X desktop, you will have to apply the «sleep fix». Put your computer to sleep. You can usually do this by quickly pressing the power button of your computer. Then, wake your computer up from sleep by pressing the power button again. You will now be able to view the Mac OS X desktop. You need to apply this fix every time you boot Mac OS X.
NOTE 2: If you needed to use the «GraphicsEnabler=No» boot flag to start Mac OS X, you can apply this boot flag permanently by installing the «GraphicsEnabler=No» option in Multibeast.
