Cubase 7.5 & Avid Artist & Mix Control

How stable is 7.5 with both the Artis & Mix Controllers rinnung on Mac 10.9? Thinking about upgrading on tomorrow but want to know will my control surfaces be stable… thank you in advance…

However I wanna do it in two steps:

1.- C 7.5 + Avid Mix (and Transport) + Mountain Lion
2.- The change to Mavericks
