    Slow iMac on HDD running Catalina going to be the next lawsuit?

    I see a lot of customers complain their iMac is running slow. We get a lot in for this and they test fine - the issue is they are running Catalina on an APFS format HDD. Plug in an ext SSD or replace the HDD for an SSD and they FLY! I think Apple may be heading for another "Slowing down my...

    On my Mac Pro 5,1 I started seeing APFS stalling issues and PCIE controller trouble especially with a Catalina disk set mounted. There is frequent beach balling during heavy disk activities. Correlation is not causation. But has anybody else seen issues? My MacBook Pro 2018 seems fine.
