Logic now rescans ALL plugins after restart..... Grrr!

Every time I restart my Mac, Logic rescans ALL plugins.

I've totally uninstalled Logic, ensuring all associated files were removed from preferences, and then resinstalled it. The problem persists.

I am at a loss as to how to stop it from doing this. With about 300 or so plugins it takes forever to rescan every time.

Most of the time I just sleep the Mac when not in use avoiding the rescan, but I feel there must be a solution to this.

I've followed several other suggestions via other posts on this forum but none seem to have helped.

Thanks in advance.
