The Z590i Vision D might be exactly the thing I’ve been waiting for! I’ve occasionally expressed an interest in building a mini-ITX system, and this seems to fit the bill very well. However, some questions remain regarding macOS compatibility with this platform. Will see how this saga unfolds over the next couple of months before release.

Nice!
I’m going to build a mini itx system too. I’m starting to piece together the hardware. I have the white cooler master nr200p case. I need to get a sff power supply next. I don’t know if I’m gonna get z590 or wait for alder lake/zen 4. We’ll see. But the mini itx vision d z590 sure is tempting!

And yea, with Apple M-series chips so damn fast and efficient, they’re a compelling purchase compared to x86. And given that apple will (likely) not release new intel hardware, it’s not clear if or how new intel tech will be supported in macOS. Like the new thunderbolt 4.0 controller or alder lake’s hybrid x86 big.Little architecture. The kernel scheduler needs to be tuned properly to take advantage of the little cores vs the big cores and while Big Sur does this for m1, it’s not clear if it (or its successor) will do the same for x86.

Rocket Lake-S seems (11th gen) seems promising to be compatible with MacOS: it's pin compatible to 10th gen, seems like a cousin to comet lake.
The big question is Alder Lake, only time will tell.

Another interesting thing will be TB4: Apple doesn't have a TB4 device yet, so our great SSDT/firmware solution can face some uncertainties for sure.

Agree that Rocket Lake should run macOS. We may have to spoof CPUID. Also, one major Change with Rocket Lake is the iGPU tech, so I’m curious to see how that interacts with macOS. Also, it would be cool if the Wi-Fi 6e controller worked out of the box on macOS... but Apple has gone it’s own way in that regard.

Apple implemented Thunderbolt and USB4 into their M1 chip... macOS currently supports Thunderbolt 3 Alpine Ridge and Titan Ridge... but we don’t know if it supports Thunderbolt 4 Maple Ridge...and even if it does, will the community need (or be able) to enable Tthunderbolt buss and hot plug in macOS on Maple Ridge (or will it just work out of the box?).

2021 will be interesting indeed.

iGPU can be very interesting: seems quite some performance improvement for HEVC folks but none of the real Mac has that so driver can be an issue.

The uncertain part is that Mac doesn't have TB4 yet. Also TB4 double the required bandwidth on PCIe side so seems like a hardware requirement that AR/TR don't have.
My personal guess is that @CaseySJ and folks will make TB4 work like a TB3 device just like AR/TR. So we will have full TB3 function just like Z390/Z490, but not technically a full TB4 function. Later on, when Mac has its TB4 (hopefully with MR), then we will get full TB4.
From a practical perspective, we actually don't really care about all those 40G stuff: most of the TB3 devices won't even utilize more than 10G. NAS are fairly demanding in bandwidth but the bottleneck is at the drive side, not IO. Audio box will be completely fine with 10G. So we need TB3 functionality (hotplug, thunderbolt bridge etc.) rather than performance.

The new M1 Macs have TB4 already. Apple can't call it that for legal reasons. Theirs doesn't meet all of the Intel requirements to call it TB4. Source: Max Yuryev learned this from OWC. Tim Standing at OWC discovered this.

Although the new Macs have only two Thunderbolt ports, compared to four on the Intel-based 13-inch MacBook Pro and Mac mini, Standing discovered that each port has its own Thunderbolt bus. By comparison, each pair of Thunderbolt ports on the Intel-based Macs share a bus, meaning that they also share bandwidth. If you plug two fast drives into ports that share a bus, performance suffers. Standing also notes that the M1-based Macs have Thunderbolt 4, which differs from Apple’s implementation of Thunderbolt 3 in only one fundamental way: Thunderbolt 4 adds support for Thunderbolt hubs that let you add more ports.

So yes, the M1-based Macs may have only two Thunderbolt ports, but they’ll both provide full bandwidth and allow users to add more ports through a hub.

PCIe 4.0 works fine on my Ryzontosh.
