Slow Navigation Within Drive in Rekordbox

 Hey guys, 

I am having an issue using rekordbox on my mac. Whenever I plug in my flash drive and navigate to devices, then try to navigate within my playlist in the device, it bogs down my laptop. I get spinning wheels and rekordbox becomes unresponsive.

I am using rekodbox 4.1.1 and it only seems to happen on the mac

Cheers.
