Hi, 

When I open Rekordbox everything is crashing down. My Mac Book Pro get's the white Screen and then it turns black...never had it. It seems like there is a virus file that i've put into my music collection lately. If yes, how can i find it?..

I have done the following or have the following setup:

> Running on MAC OS Sierra 10.12.4 (Latest)

> Nothing connected to apple mac

>Rekordbox 4.3.0.0020
