Z490 & Z590 - Will Z590 ever have macOS Support ?

Yeah these early Z590 BIOS' are a mess. On MSI, before I returned it, it wouldn't hold an all-core overclock on Rocket Lake in Cinebench... it would down clock to 4.6 GHz. I've heard YouTubers complaining about the same thing.

At least the f5a BIOS on Gigabyte didn't have that issue if you disable TVB frequency clipping. But Thunderbolt hot plug is broken. I reached out to Gigabyte last week about missing hot plug and some other weird quirks in their BIOS. For instance, if you disable the Thunderbolt controller, save, restart, the Tthunderbolt settings disappear from the BIOS, and you can't access them until you clear CMOS or load Optimized Defaults.

They haven't gotten back to me yet. But it seems that Gigabyte has pulled F5a (at least from their worldwide site, not sure about other locales) from their website: https://www.gigabyte.com/Motherboard/Z590-VISION-D-rev-10/support#support-dl-bios

I have had the same experience with the Gigabyte Z590i Vision D.

I have found out, that Disabling the TVB frequency clipping and setting the CoreCurrent Limit(Amps) with the Core Power Limits to a higher value like 250A helps. But getting a good OC and setting Powerlimits to fit your cooling is working weird right now.

And I couldn't really get a much better result than just loading default settings and then enabling Adaptive Boost Technology. This is what I am using now.

This was my best yet: https://browser.geekbench.com/v5/cpu/7280853

And this is what XMP+ABT gives me: https://browser.geekbench.com/v5/cpu/7293848

Nice! Slightly better than me: https://browser.geekbench.com/v5/cpu/7292722

Hey @CaseySJ ,

I have received my 11900k today, the Gigabyte Z590i Vision D a couple of weeks ago.

So I used the meantime to create a config and do a USB-Port mapping etc.

The config instantly booted to macOS and even detected my W5500 via TB in an Razer Core X. Didn't expect that. Everything running very smooth.

But the TB has no hot plug yet, but this is also hard to test for me, as the only TB device I have is the eGPU which is required to get display output.

I noticed that the Thunderbolt is not under RP05. It is listed under PCI Bridge etc. (Have no access to my system over the weekend and didn't do a IORegistryExplorer and no MacIASL Export yet)

Is this a good sign?

I have used your previous SSDT-TB3HP-JHL8540-GIGABYTE-Z590i-VISION-D.aml and left the BIOS settings at default. So Security Controlled by the OS is set to enabled. And GPIO Force Power is set disabled (I know, should be enabled, but TB works without it).

I am also willing to do some further testing of the TB SSDTs etc. I would also try to flash the TB ROM if necessary, but I am not sure if my clamp fits where the TB ROM chip sits and I don't have the soldering tools to desolder the ROM chip.

Thank you for the SSDTs. I can start to support further at Sunday evening/monday. Took next week off, so plenty of time :).

I will also share my config on Github.

Best,
Chris

Hi! Can ask you......
Can you update macOs and apps through App Store normally with the Rocket Lake CPU 11900K?

I have news about this, and it is bad. I was going to test this earlier but it seems others have beaten me to it. The reports from ****** on the latest Opencore build just released has confirmed that the Rocket Lake IGPU simply cannot run with macOS, and in fact it has to be disabled before it gets recognized by the system at bootup. So most are running/testing it with a dGPU instead.

On the other hand, 10th gen Comet Lake IGPU should to be able to run in macOS with a dGPU (from what I remember) and can also run HEVC and 4K decoding via IGPU if the device properties is setup properly.

Uh oh. That's bad. I'm sure those who tried adequate spoofing before calling it quits... Can you drop a link to the thread where they posted their findings?
I do encourage you to try yourself too, because you might be able to make it work even while someone else couldn't.

Sure. Why not? :D

Just did an Update to OC 0.6.8 and then a Big Sur Update to Public Beta 6.

Good to hear that you've gotten some feedback. Hopefully the convo is productive and they fix it. I'm still waiting to hear back.

I have good contact. I have a direct email and phone number for him. This is our local Gigabyte service technician. Pass the problems to Taiwan.

Does it really matter if I've got an AMD GPU installed? Wouldn't I be better off with a dGPU anyway?
