Issue with Rekordbox 5 > 6 Upgrade (HDD Space)

Hi all,

I am attempting to upgrade from the last/final version of RB5 to the current/latest version of RB6 (6.6.1). 

I'm running MacOS Mojave 10.14.6 on a Macbook Pro.

Space is at a bit of a premium. I split my library between an SD card and the main drive, but I've freed up 33GB on my main drive now. However it still tells me there's not enough space when I get to the initial library conversion step in RB6:

What is the space requirement for this? I know for a fact my RB5 database is nowhere near 30+ GB... 

Any help would be appreciated!!

Thanks

Nite
