I'm currently experiencing the RGB Pinwheel and "Rekordbox not responding" in Activity Monitor, followed by a kernel panic/crash and computer auto-reboot.
I believe I've narrowed it down to playing a .wav file in export/analyze mode and then while playing selecting another file.
I did also experience slowdowns this past weekend while in Performance Mode in both standard Rekordbox and Rekordbox Beta 5. I would receive a pinwheel, the mixer section of my RZ would appear to freeze, and then the song would eventually load.
I'm reporting for others that may experience this.
I am currently cloning my drive, as my suspicion is that it's an issue with either the USB 3.0 or the drive is going bad. I have a Thunderbolt drive on the way from Amazon. I'll update with progress.
