On OS13, the ethernet window is blank in system services: network: ethernet. Do I have a broken download or ???

I have done clean installs several times, but the ethernet panel is always blank on a mac mini - m1

?

If in doubt search DNS...

Are you saying that this settings pane is blank or doesn't exist?

If that's the case then give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.

NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.

As I said, it is blank.

To trouble shoot further you can:

 Try SafeBoot How to use safe mode on your Mac - Apple Support will sort many anomalies

Login and test, reboot as normal and test..

Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

all known to cause issues on the macOS

I have the same condition of the OP. 27" iMac. And not just for the ethernet settings but also for the wifi settings.

Clicking on 'details' takes me to a blank pane, not the expected pane that allows modification of the settings.

In addition, if I click 'details' the blank screen is presented and I cannot return (go left) to 'Networks'. I can however click any other setting on the left and it will 'return' to the left pane.

All the replies here suggesting work arounds do NOT work. Using search for DNS Servers gives a blank screen.

Choosing TCP/IP on the search results briefly flashes (if you blink you will miss it) the correct details before presenting a blank screen.

My network setting correctly says 'connected' for both ethernet and wifi.

If I use the terminal command 'networksetup' the output of various parameters is correct for ethernet and Wi-Fi. I have no problems with connectivity.

I spent an hour or so on the phone with 'tech support' who walked me through all sorts of stuff, including download & reinstalling Ventura. Nothing worked, including safe mode. His final suggestion was to wipe my SSD and reinstall OS and my time machine. I have not done this, hoping that 13.2 fixes this issue. I did submit a comment to feedback but since one never knows if it is read and/or acted on I can only hope.

The Apple Gods did not remedy this situation w/13.2. There are not a lot reports that I have seen but there was a new one that appeared after 13.2 was installed. So this is still happening. Maybe they can't fix it because they can't replicate it

Thanks for your reply, good/bad to know I am not the only one with a problem. Let's hope the Apple Gods are looking on with favor to our plight and get an update into the next release.

Have you installed and run any "cleaning", "optimizing", "speed-up", anti-virus or VPN apps on your Mac?

None that I am aware of, other than Xcode, and CarbonCopyCloner, Safari, iTerm2, Numbers, Pages, TextMate,etc. I have only Solitare Epic and Mahyoun II as games.

And I have not installed any of the type of apps you listed.
