Logic Board Replaced, Can’t Re-Authorize

Delete this file…

Library/Application Support/ProApps/Final Cut Studio System ID

Deleted the System ID file, it still won’t accept the serial number.

Time to call apple support. If you registered they will help you.

I went through this exact problem a few weeks ago… I wish I took better notes, but I can give you a rough idea of how I fixed it. First, I ran FCS remover https://www.digitalrebellion.com/fcs_remover.htm

Then, I searched through ALL my library folders for anything FinalCut, FCS, or ProApp. All these files went into the trash. Finally, I reinstalled FCS and bingo.

Don’t bother calling Final Cut support. They will charge you $200 to tell you to trash your system preferences.

Thanks for the input. I already spent 3 hours reinstalling and it still won’t take the serial numbers.

I’ll try the FCS remover.

Sigh.

I did the FCS remover and trashed all the files. The installer will not accept the serial number.
