Best version of Rekordbox 5 for MacOS Catalina

Hi all, 

Until the unresponsiveness of RB6 and Catalina has been corrected in a future release, I am going to install RB5, as I understand it works as a seperate application, and I have a license, so why not. 

Which verison of 5 that has RGB waveforms would people consider the fastest? Not necessarily the most feature rich, but just the one that runs the best on a MacBook Pro mid-2012 i7 8gb RAM?

Cheers
