FCPX is Beachballing and Slow/Lagging on MBP M1 Pro 64GB RAM
Per instructions from another thread here's a quick recap and EtreCheck Report
I did a migration from my 2014 MBP and most everything works amazingly well except FCPX which I use heavily. It takes 2 minutes just to load and lags with processing and pulling files from any drive. Full Disk Access has been given to FCPX and while I do have Chrome on here I removed and that did not help. Based on further comments from Tom Wolsky I have no attachment and can remove as long as Firefox will work with StreamElements.com a site I use for stream applications.
