Rekordbox 5.5 Buggy & XDJ-RX2 Drop Outs!

So I Installed Rekordbox 5.5 on my Macbook Pro 15 Retina... Kept getting stuck on loading after opening... had to uninstall and roll back to 5.4.3

Also has there been any fix to the XDJ-RX2 on rekordbox. I have two, the black one and the LE white edition. They both fail with Rekordbox DJ on me... Especially when DJing with USBs, when I switch to Midi, I seem to get drop outs after a while until it completely halts. I haven't tried with the new firmware update, but I'm wondering if this is something Pioneer is aware of.

I mainly mix with USBs but still use the software for music videos, which forces me to carry my xdj-rx2 for usbs and my ddj-1000 for rekordbox dj, but this is kind of a pain, especially when the xdj-rx2 should be capable of both.

Thanks!
