I tried installing from my old MacBook Pro after I recently updated its operating system and apps.
Problem of last two days that Apple support could not help with:įirst, I have been unable to install thunderbolt 1.2 firmware update for the past month from my MacBook Pro Retina. I hope this helps people out with the issue i was having.my Thunderbolt auto detected and i could start using it again. If your worried about this file, make a copy of it before editing.īelow is an example of JUST ONE SECTION i copied out of my file and highlighted where i found the interface name After the reboot, insert the Thunderbolt Ethernet Adapter and give it a minute or two to show up in your Network Preferences. After you remove all sections that contain a Thunderbolt interface definition. If it asked for permission to unlock the file, click unlock.ĩ.
You will have to provide a password to allow this to be edited and saved. That gets removed with the whole section.Ĩ. That is likely where you find the friendly name of your interface. I will note that you will likely find a and sub section indented inside a section. Remove the entire section including the starting and the ending for that section. These sections define the info on the interface.ħ. Thunderbolt, Thunderbolt1, and Thunderbolt2. Inside each section you want to search for the word "Thunderbolt." I am attaching a sample image with 1 section by itself for ease of viewing.Ħ. This file is organized using XML headers meaning marks the beginning of a section, and marks the end of that section and then repeats.ĥ. Enter /Library/Preferences/SystemConfigurationģ. unplug the Thunderbolt Ethernet adapter and reboot.Ģ. I didn't have an success with using the GUI tools to do this, i edited a plist file manually. What i found is that the easiest way to make sure your system detects it as a new device is to clear out the definition for the old one and let it re-detect.
This post is for those that see it, but cannot get the device to show up (auto detect) in the Network Preferences part of System Preferences. If you don't see it, you may have a thunderbolt bus issue or your adapter could be bad.
If you see it, your half way there to resolution.
