[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

[jiffyslot]

I am running a iMac19,1 config with this build

I've got a question regarding changing the SSD-Configuration after installing (running Mojave).
Currently I got one 1TB nvm2 Samsung 970 Pro running, split into to partitions (one OS, one HomeFOLDER).
The SSD crashed recently (complete freeze, repaired in the recovery mode) and became unreliable.
So now I bought a XPG 256 GB (the one from the guide) and a 970 EVO 1TB and want to use the small one for OS and the BIG one for Home Folder.
I got a CARBON COPY CLONER-copy from my OS-Partition (before the crash, so I think I could continue working twith it) and from my HOME-Parition.
I thought to clone the OS-Partition to the new SSD via CCC and a external nvm2-Case and do the same with the Home-Partition and then install both of them onto the gigabyte-mobo.
Do you think this will work? Or will there be trouble of the OS recognizing the Cloned Home-Folder-Drive?

any help appreciatet!

I have a couple NVMe SSDs as well. Me: I'd use one SSD for the OS, etc., and setup the other as some sort of media SSD. I wouldn't combine or split SSDs. I made a RAID 1 with a BMD Multidock and 4 1TB 860 EVOs. I didn't care for it, so I changed everything back. YMMV.

I recently cloned the Catalina install from my MacBook Pro to my newly built computer, with a WD Blue 1Tb nvme drive, and it works no problem. It's been working fine for me for a couple weeks now, and I also upgraded it to Big Sur (first 11.2, then 11.2.2, then 11.2.3). The only oddity I've noticed is that for the .2 and .3 updates, it took a number of reboots (3-4), and in the past on "real" mMacs, it's typically just 1 or 2, and it asked me to login with my Apple ID the final time, prior to logging into the Mac.

Here's a something interesting that I just can't figure out:

I'm using an iMP 1,1 config with this build.
If I turn on the iGPU in the BIOS but keep it "off" in the config file, I still get a boost (over not activating the iGPU) when running a Geekbench test. See attached config.

Although WhateverGreen properties are not specified in your config.plist, it is possible that macOS is activating the iGPU automatically. If you post the IOReg file, we can take a closer look. Specifically, we're looking for IGPU@2 with AppleIntelFramebuffer as a child node. Then we want to see what Platform ID is being used, which we can see from front page of Hackintool.

Good question and glad you asked, because this can be tricky! Here is my suggestion:

• Install Mojave from scratch on the XPG 256GB SSD.
  • Format the XPG drive in Disk Utility with:
    • Name: Anything
    • Format: APFS
    • Scheme: GUID Partition Map
  • Mount EFI partitions of old boot disk and new XPG SSD.
  • Copy EFI folder from old boot disk to new XPG SSD (to EFI partition).
  • This ensures that same serial numbers are used.
• When the Mojave welcome screen appears, create your user account.
  • Use the same account name as before.
  • The account will be created on the XPG SSD (which is okay for now).
• Format the new 970 EVO 1TB disk in Disk Utility as APFS.
  • This is your new home/user disk.
• Use Carbon Copy Cloner to clone the old Home Disk/Partition to the new 970 EVO 1TB disk.
• Now open System Preferences --> Users & Groups --> Advanced, and change the location of home folder to the 970 EVO 1TB disk.
• Next, reinstall all of your Applications to the XPG 256GB SSD.
  • You can mount the old OS Disk/Partition and use Finder to copy most third-party apps from the old Applications folder to the new Applications folder.
  • Some applications cannot be simply dragged-and-dropped, but need to be installed through their Installer.
  • When these applications are launched, they should find existing license files. If not, it will be necessary to re-enter the license information.

As you can see, this procedure is a bit more involved. We cannot simply clone everything back. This is because you are changing the disk topology. In other words:

• You are going from a single 1TB NVMe SSD with 2 APFS partitions --> to --> one 256GB SSD and one 1TB SSD, both with 1 APFS partition.
• This is why the recovery process is a bit more involved.

Fortunately, those reboots are quite normal on Hackintosh.

@jiffyslot

That explains a lot:

• iGPU is accelerated automatically
• Platform ID is 0x3E910003 (headless)

So iGPU is being used in compute tasks (H.264, HEVC, QuickLook, Preview, etc.).

Have you tried Screen Mirroring from Big Sur to Apple TV?

I’m using iMacPro1,1 with only AMD GPU (no iGPU in my CPU)
shikigva=128
I’ve the sound but not the video
It used to fully work in Catalina
Any idea what I can do?

The same with shikigva=80 with AppleTV 4K, but OK with AppleTV A1469 (3rd generation).

1. Yes - pretty confident that went okay, especially cause it works with the tbtOnPch SSDT.
2. Even pre-connected devices. It has always been pretty funny, hence why I was exploring the options here. Usually, if I disconnect AC from the comp, it takes sometimes MANY cold boots and reboots to get Thunderbolt working again (on pre-connected devices). Once it is working, it connects consistently on every reboot as long as AC power is not lost. It could be that I just need to keep cold booting and rebooting for a while longer, but it has never been quite this bad.
3. Yes, they worked without an SSDT and also with the SSDT-TB3 from another thread on this forum.

It may be a good idea to perform a CMOS Reset, which will require BIOS parameters to be configured again.
