Yosemite upgrade and network locations

Yosemite upgrade and network locations

Day to day I’m often at various sites most of which have some form of proxy configuration. To save myself having to change and remember the specific details for each site / customer, I normally create a new location for each site and switch using the Apple menu (there’s your pro tip for this post!)

When I upgraded to Yosemite (10.10.0) from Mavericks (10.9.5), I found that I had lost all but my default network settings. No Network Locations and no VPN configurations.

That sucks, what did you do?

As always, I took a full disk image of my Hard Drive prior to the upgrade, ‘just in case’ and this was one of the rare times when I had to use it.

I mounted my previous system and grabbed my network locations preference file from its backup location, restored it into the same place on my upgraded OS and restarted my laptop. Once complete, all my locations and VPN settings were restored and operational.

Say that again but slower!

Fair enough.

  1. I mounted the disk image of my OS from before the upgrade.
  2. On this mounted disk image, I found the network preference file located at “/Volumes/[name of my backup image]/Library/Preferences/SystemConfiguration/preferences.plist”
  3. I manually dragged a copy of this file from the above location to the same location on my booted YoYo system (“/Library/Preferences/SystemConfiguration/”) and replaced the file that was already present.
  4. I entered my administration username and password and rebooted the Mac.

That’s it!


Hopefully, if anyone else hits the same issue, this will help. AND ALWAYS TAKE A BACKUP BEFORE AN UPGRADE!

As always, if you have any questions, queries or comments, let us know below, and I’ll try to respond to and delve into as many as I can.
