@CaseySJ So I decided to do a brand new clean install of Catalina, but rather than just running an updated, I wanted to essentially start everything from scratch.

I followed the build guide step-by-step and got everything running beautifully. But just as before, I have one bizarre issue: my CPU is pretty much idle non-stop. It hovers around 85%–95% idle. Opening apps takes quite a while, various tasks take much longer than they should on a powerful machine like this. I pretty much never see any spike in CPU load in Activity Monitor. Any ideas as to why this may be?

My setup:
Gigabyte Z390 Designare f6
Intel Core i9-9900K
AMD RX 580 8 GB
64 GB 2666 MHz DDR4
Model Identifier: iMac19,1
Internal Drive: Samsung SSD 860 EVO 1TB
In BIOS: XMP Profile is disabled and the multiplier is set to DDR4-2666

Would REALLY appreciate the help.
Perhaps Spotlight indexing is taking place? We can also run Activity Monitor and sort the list by “%cpu” to see which process is consuming excess time.

Hi Everyone. I hope I'm in the good section. Sorry for my bad English as I'm French. ;-)

I have problems with my Thunderbolt 3 (USB C). it doesn't work with my Sound Card Apollo 16 even with my hardrive lacie.
In my OS system (Big Sur 11.6.2 ), at Thunderbolt section appears " No Found".

I m a little bit lost . I have to flash my motherboard ? Or only Thunderbolt stuff ?

I have a :
Gigabyte Z390 Designare (BIOS F9)
Intel i9
AMD Radeon 6900 XT
OpenCore

Thanks.

Usually UAD TB Sound Cards works out-of-box.

Have you configured your BIOS as in Post #1 ?
Have you correctly installed UAD drivers ?

If yes then:
  1. Connect the sound card to your hackintosh then switch ON.
  2. Download and run IORegistryExplorer and export the file with "File —> Save As…".
  3. Post the file

Note:
I assume you are using an EFI created by Casey.

When TB isn't flashed your UAD will appear in System Information --> PCI instead of System Information --> Thunderbolt.

Hello @oLiMonKeY,

Some comments:
  • As @Inqnuam mentioned, UAD Apollo devices usually work well without flashing the Thunderbolt firmware. Please try setting Thunderbolt --> Thunderbolt Boot Support --> Boot Once in BIOS.
  • Regarding the LaCie hard drive, what is the make and model of that drive?
