Thunderbolt monitor Ethernet adapter causes network preferences pane to crash

Question

I have a 2014 Macbook Pro 15" running 10.9.3, connected via Thunderbolt to two Apple Thunderbolt monitors. Each monitor has an Ethernet jack.

The Ethernet seems to pick up an IP address, but doesn't work unless I turn of Wi-Fi, then disconnect my VPN, then pull the Ethernet and reconnect it.

When I plug in my ethernet cable to monitor, the Network Preferences pane crashes every time I open it.

Answer 1

I had this same issue (10.11.1). It was triggered in my case by plugging an ethernet cable into a 5k iMac that had previously only ever used WiFi. The network preferences pane would hang and com.apple.preference.network.remoteservice was shown as taking 100% CPU and "(not responding)" in Activity Monitor.

I tried deleting several network related files in /Library/Preferences but the one that seemed to do the trick was /Library/Preferences/SystemConfiguration/preferences.plist. Deleting that file and rebooting allowed me to load Network Preferences, and everything seems good now.

Answer 2

i have had a couple os installs where changing ANY network setting caused the pref pane to crash. this included enabling disabling ports. makes no sense, but it doesn't seem unique when i was looking into it.

what i did to fix it was to remove the prefs for the pref pane and start fresh. it could have something in the plist from a previous device that's messing it up.

i'd suggest removing all interfaces from the network pref pane and adding them again.

if it's more stubborn than that, you can remove the plists, perhaps the ones below: be sure to leave backups or renamed files and reboot.

/Library/Managed Preferences/com.apple.networkConnect.plist

/Library/Preferences/com.apple.preference.network.remoteservice.plist

Answer 3

Deleting all /Library/Preferences/ worked for me. I'm now at 59 days of uptime... no crashes from network prefs anymore. 10.9.5 as well.

Answer 4

Make a backup and delete all /Library/Preferences/

sudo rm -rf /Library/Preferences/*

Reboot and you should have the problem fixed.... it did work for me... running 10.9.5 beta here.
