How do I edit a plist file in Terminal and save the changes ?
The file is SystemVersion.plist

You could try defaults write.

Could you walk me through as I haven't done this before. I purely want to alter the version number in the file, save it, install a firmware update, then change the version number back again.
Saying things like 'defaults write' unfortunately is no help.

Sorry you didn't find that helpful. Checkout man defaults. Maybe someone else can chip in, I'm pretty busy right now.
Hi
You have to have a password set for the local admin account for this to work:
sudo nano /System/Library/CoreServices/SystemVersion.plist
Make your changes by navigating to the relevant place using the arrow keys. Control+o (WriteOut) will write the change. You'll be asked to write the file. A carriage return should do this. Control+x will exit from nano. It's always a good idea to make a back up of the file first. Something like:
sudo cp -R /System/Library/CoreServices/SystemVersion.plist /System/Library/CoreServices/SystemVersion.plist.bak
Nano is one of many terminal editors you could have used? Issuing man nano should tell you more.
