Kill the Final Cut registration screen

I came across this nicely detailed post explaining how to get rid of the forced registration screen of Final Cut Pro/Studio, which always pops up when you really don't want to be bothered with this idiocy.

But I felt the solution was worse than the problem. It involved far too much clicking around for my taste. And you need the Property List Editor. You only have that once you have installed over 1 GB (!!) of developer tools. If you can remember where you put your OS X disk, that is.

Surely, there must be a better way to do it, by just copying a command from some web page and pasting it into Terminal?

It turned out to be 3 commands. And getting them right was much worse than the solution I din't like. You need your machine ID, which is in an XML file that defaults read doesn't want to read. And in that file it is encoded in Base64. You need to put this ID into a property list file as data. That can be done with defaults write, but the data needs to be in hex. I should just have registered, I guess...

Anyway, the detailed explanations are in the link of the first sentence, and the 3 ridiculous commands to paste into Terminal are here:

id=$(perl -MMIME::Base64 -ne '/^\s+(\S{64})\s*$/ && print unpack("H*",decode_base64($1));' "/Library/Application Support/ProApps/Final Cut Studio System ID"|tail -1)
sudo defaults write /Library/Preferences/com.apple.RegFinalCutStudio "{ AECoreTechRegister=1; AECoreTechRegSent=1; }"
sudo defaults write /Library/Preferences/com.apple.RegFinalCutStudio AECoreTechRegInfo -data "$id"
