I risked Yosemite last Saturday morning.
Best update ever, I started with OS 6, only the Wacom driver needed renewing.
To my surprise everything really is running faster, best I have seen on this MacBook Pro 6,1.
The green button function has changed, but cntrl + button does what used to be just button to fill screen.
