Mac Studio Ultra Ethernet and Wifi Connection Issues?
Just received my Mac Studio Ultra two days ago. I set it up using Migration Assistant from a 2020 iMac 5k. Both machines were running Monterey 12.4. The transfer worked fine, UNTIL I tried to connect the Ultra first to my ethernet, and then to my wifi system. I have Xfinity Gigabit internet with the Xfinity supplied modem. I also have an eero 6 mesh router. Just for fun, I also have Century Link as a backup provider on a totally different router/modem, which functions as internet access wifi for our guests. In the past, bringing any new machine on line was as simple as giving people the correct password.
xfinity is our primary and I plugged the Cat 6 cable into the ethernet port on the Ultra. Nothing except “no connection”. I unplugged everything, shut down the computer, rebooted the router and when it came back to life, I plugged in the cable to the router, then to the Netgear Gigabit switch, and from there to the ultra. Nothing. So, this time, I bypassed the switch, and connected the router directly to the computer. Nothing. Now, completely baffled, I started looking in detail at the specifics of the network connection. I can plug any other device - MacBook Pro (last Intel model), the old (2020) iMac - and have instant access to the network either via direct ethernet connection, or via wifi. With the Ultra, nothing works, not wifi, not ethernet (I even tried a different cable, and also used the cat5/6 adapter to Thunderbolt (which works fine with my 2019 MacBook Pro 16).
After searching the interwebs (including this site), there seem to be lots of people with related problems, having to do with the fact that the ethernet port on the ultra is a 10 Gigabit port). I tried a number of these different solutions (including deleting about 5 plist files from Preferences), and killing mDNSresponder. After rebooting, I was able to access both wifi and ethernet UNTIL I discovered that I had to enable third party extensions by booting into the Security panel. Got that solved, but when the machine rebooted after dealing with the security issues, I once again had no ethernet connection and no wifi. I repeated the steps again that got me to the internet in the first place, but there was no joy again.
Has anyone figured out a surefire and consistent way to connect to both ethernet and wifi? Otherwise, the ultra isn’t very useful.
HELP.
Mac Studio, macOS 12.5
