already in use “******-macbook-pro.local”
I'm trying to open libraries but the message "“LA” is already in use by “*******” on “********-macbook-pro.local”." Keeps popping up. I have tried restarting and uninstalling and reinstalling FCPX but this problem keeps popping up. I've checked other solutions but none of them seem to help. Hopefully, someone else knows how to fix this.
MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13.6)
