Hi, after I installed the beta 2, I can't connect to the internet or use Mail, using the Ethernet service.
System preferences shows Ethernet and wi-fi (both green lights). As soon as I disconnect the Ethernet cable I'm able to use the internet using wi-fi.
I have reinstalled the Operating system twice, my IPs provider has confirmed the that my system is ok, I have changed the cable, Apple service couldn't find an answer.
Os Sonoma
Version 14.0 Beta (23A5286i)
Mac Mini M1

You obviously checked wether the cable is correctly connected on you mac as well as on your router/switch - and the ports are indeed working (?)… because your Mac indicates a working internet connection via ethernet with the green symbol :

What IP adress is assigned when you have the ethernet cable connected? What are the DNS settings on it? If there is any Proxy used (e.g. for adblocking) turn it off. Is there some kind of error message when you try to open e.g. a webpage when connected via ethernet?


EDIT: please update to beta 3. Check. :cool:

Hi, IP: adress is 192.168.1.105 DNS: servers 192.168.1.1 Router:192.168.1.1 There's no proxies all are off in the Ethernet option.
Checking software update I get the message Your Mac is up to date.
Yesterday checking all the settings I turned Private Relay on and off and was able to open three different sites, but then stopped again.
I'm going
When trying to open a web page after a few minutes I get the following message:

You’re not connected​

And the web just isn't the same without you. Let's get you back online!

Try:
  • Checking your network cables, modem and routers
  • Reconnecting to your wireless network
  • As soon as I disconnect the Ethernet cacle I get connected using wi-fi.

Since it was introduced, iCloud Private Relay has been the main cause for connectivity issues on macOS.
Disable iCloud Private Relay https://support.apple.com/en-us/HT212614 and Hide IP address https://support.apple.com/guide/safari/privacy-sfri35610/mac

Disable iCloud Private Relay with a configuration profile

In whatever order:

  • Follow @bogdanw recommendation and turn off private relay and Hide IP Adress. Then you should delete the current ethernet service (Network > right-click on Ethernet and Delete Service) and add a new one (more option > Add Service…). Then, because automatic discovery sometimes takes a moment, select Ethernet, And Choose, Make Active. Check.
or
  • Create a new user. Login as this user. Check.

I thought that the issue was solved but the fix lasts about three minutes and if Want to keep using the Ethernet I have to re-start the computer.
Is there a chance that the port is faulty (hardware?)
 
my first suspicion would be that the update to the Sonoma beta is the culprit.

Not sure wether this still works on Sonoma, but you can execute in the terminal

grep en0 /var/log/system.log

to try to pinpoint the issue. For sure you find this info via the Console app - but personally I find that slightly more tedious. YMMV obviously. 🤓
 
Hi, I just followed all the steps being sugested again and the computer has been working normaly for the last 30 minutes. Maybe I didn't follow all your instructions properly before.

Slatibart, I created a new admin user and all works fine, but I got a new question, can I copy the movies, music, and pictures folders to the new admin and delete the corrupted admin account?
 
*Fix was to create a new "Location" in network settings. That for whatever reason fixed the DNS issue on the wired interface.

Having the same issue on my iMac M1 with current dev beta. DNS on the built in eth port no longer works. Tried reboot, delete eth service and create new. I can ping to IPs, just DNS is dead. Tried changing DNS server IP on eth int. No luck.

No issues on WiFi. No issues using a belkin eth adapter. Just the built in eth port DNS is broke. Super strange.

In general though the upgrade seems to be acting differently on this iMac. I already upgraded a M1 Air and M1 14" MBP to dev beta 4 (and was running early versions too) and no issues. I noticed after upgrading the iMac I got lots of alerts about new device, it dropped from my MDM, had to log back into Messages, lots of apps asking for persmissions to desktop, microphone, etc. It's like the upgrade reset a lot of things and that didn't occur on either of my laptops.

Steps above did not work for me (Mac Mini M2).

I then used Migration Assistant to migrate "Network Settings" from an instance of MacOS Ventura 13.6 that I had on another disk. That fixed network access for both ethernet and wifi on the Sonoma 14.0 beta.
 
Yeah latest dev beta once again broke DNS on my iMac wired interface and this time creating a new network location didn't help. So, for now I'll be working on wireless. If anyone finds a fix please post it. I don't have a Ventura machine to do what's mentioned above.

Do you have an old disk lying around which you could use to install Ventura temporarily? You could migrate network settings from there. That's how I did it.

I believe you could also use Migration Assistant to migrate working network settings from a Time Machine backup if you have one. The source can be an earlier MacOS version. Migration Assistant lets you selectively migrate network settings, and nothing else, if that's what you want to do.
