#1 piece of advice for "Security Update"s from Apple...DON'T RUN IT WITHOUT THINKING !!! (ie, see if new Web Driver out yet)
With 10.12.2 going official there were new Secuirt Updates for 10.10 and 10.11.
And both broke Web Drivers
And now we're getting emails.
Best bet for now is to use the "Beta" driver for that OS. I know this work for 15G1212, haven't got word on the 10.10 OS.
Look before you leap and always wait for the WebDriver !
We will update the driver page within 24hrs of Nvidia releasing a fix.
