I'm writing this to all the poor souls out there that bought the Mac Mini M1 with the 10 GB adapter option:
Your Mac is probably not working at the correct network speed, and this is a hardware problem. It's not software (I think), as I have installed every possible patch, new macOS Ventura Beta's and even macOS Sonoma Developer Beta. All macOS versions shows the same problem for this ethernet adapter.
Since I bought my Mac Mini (2020) M1 with 10 GB ethernet adapter option, it never worked: it connected to the 10 GBE switch at 100 Mbps.
This could be seen using the ifconfig command or in the Network settings. Having a 1 GBE switch (NetGear) could sometimes make 1 GB speed to work. The initial connection to the switch would take between 30 seconds to over 2 minutes, if ever. As I also had Wi-Fi enabled (by default), I didn't notice this the first couple of weeks last year. When I turned off Wi-Fi, I immediately saw the problem. I brought in my Mac Mini to Apple Store, they reparied it by replacing the motherboard, but that board was had the same hardware version level, and of course, a 10 GB connection was not possible.
Apple Store did not have any hardware to test the 10 GB ethernet, and told me the Mac was functioning properly. After 7 months of relentless discussions with Apple Technicians (that could see the problem on my machine), I took my 10 GB switch with me to the Apple Store and showed them the problem. They could obviously see that it didn't work. The still insited that my Mac was working properly according to their tests.
After having sent tons of email, I then sent a letter by standard mail to Apple, Cork, Ireland, to their legal department. Their response, not written of course, only over the phone (so no written evidence whatsoever from Apple - they have been VERY careful), was that the legal department rules according to Apple Store, so my Mac Mini M1 10 GBE was fully functional.
I got frustrated and went back again to the Apple Store, this time with the 10 GB QNAP switch and the 1 GB Netgear switch to show them that it didn't work. This time, they acknowledged that itdidn't work properly and too the Mac in for repairs. After a week, they told me that the Apple support told Apple Store to replace the mother board. They did not do so, as the hardware level is still the same as the one in the machine.
The only thing I want, is a functional Mac Mini at 10 GB, so I want a refund of the Mac and its Apple Care+. Then I can buy a new Mac, this time an M2 (as the M1 is not available anymore), and hopefully that 10 GB adapter will work.
