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

That's better.

• We can see Apollo connected on Thunderbolt port 2 (DSB4) but nothing on Thunderbolt port 1 (DSB1).
• Was the LaCie connected to Thunderbolt port 1 when screenshot was taken?
• Has this LaCie drive ever worked on a Hackintosh?

Yes it was on port 1
And yes worked when my Hackintosh was in Catalina
The drive is not very important , I can transfer it to another USB deuce

But I need my Apollo for work

He still didn't answered if he is using one of your created EFIs.
Maybe it will be better that he posts the EFI then we can check imported SSDTs and the configs

Yes i can post my EFi
How to hide Mac Serial ?

In my haste I read 'DMAR' instead of 'DMAC'. We added the DMAC SSDT as an experiment to see whether it would make any difference with connection of certain Thunderbolt devices that now depend on VT-d. Although the SSDT enables the DMAC device in IOReg, we did not observe any specific benefit.

But from what I understood, it is an on-mainboard present, functioning and meaningful device. Makes still sense to implement it (at least for me), like SMBus

Because LaCie Orange is a Thunderbolt 2 device, it may not hot plug. Have you already tried connecting it before macOS boots up?

Does the Apollo have the latest firmware (on the Apollo itself, not the macOS driver)?

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.

@CaseySJ that's exactly the bizarre thing, that nothing is really using up any CPU. I've had Logic Pro X and Firefox open for a few days, but otherwise, the bigger CPU Time usage is coming from kernel_task. As you can see the overall CPU usage is really sitting on ~97% idle. The few bumps you see in the graph were moments of me opening some apps which require higher loads to see how things behave. And in each case, I never bumped over 85% idle (so max 15% CPU usage). It's as if the Hackintosh isn't allocating all the resources it could.

I double-clicked the graph to open the CPU History and discovered a strange thing, the graph assumes I have 16 cores, where this is an 8-core machine. It's only showing activity on the odd-numbered cores (so 8 cores total, which I guess is correct). Does the load distribution look correct?

The i9-9900K is an 8-core but 16-thread processor. The 16 threads are also known a Logical Processors, which is what Activity Monitor is showing.

Now that a couple of days have gone by, is the system still sluggish? If so, can you describe some specific examples of sluggishness?

This is actually normal, Hyper Threading !

Yes Apollo have the last driver.
I recheck it tomorrow morning

Two more suggestions:

• Perform a hard reset on the Apollo.
• Then boot macOS, run IORegistryExplorer, scroll to RP05 section again, and post screenshot of the complete RP05 tree.

Thanks for the explanation @CaseySJ - yes, the sluggishness still happens. For example, right now, I opened System Preferences. The main window opened fast, but then clicking on any of the sub-sections gave me the spinning wheel and took ~15 seconds to load the sub-section. I've experienced the same behavior navigating in Finder. And at no point does any process go over 9% in Activity Monitor.
