You have to hack the plugin.
Found this a while back somewhere
1. Install the new Canon EOS MOVIE Plugin-E1 for Final Cut Pro (https://www.usa.canon.com/consumer/co…nloadDetailAct)
2. Go to Library/Application Support/ProApps/MIO/RAD/Plugins/CanonE1.RADPLug/Contents/Resources/
2. Open up cameras.plist (this didn’t work when I opened up the file in TextEdit or a word processor, I had to use TextWrangler or BBedit) I would also back up the file before opening it.
3. After the 7D info add the following lines of code (keeping to the coding structure):
T2i
Canon EOS REBEL T2i
4. Save the text file. Close it. Everything should work now.
This is working on my MBP and MacPro
