MetalPerformanceShaders causes Messages, Mail, FaceTime crash in 10.12

Hey everyone. I've got Sierra public beta running on my P55-UD3 with 660ti graphics and have finally figured out what is causing crashes with Apple apps. Any app that uses MetalPerformanceShaders crashes as soon as it is used. So far Messages, FaceTime, Mail, and sometimes Safari are affected. If I boot with nv_disable=1, All of the apps work. I haven't tried uninstalling the Nvidia web drivers yet. I am starting a thread because I haven't found anyone else with this issue. If anyone has an idea for a workaround, I would be grateful. Thanks!

I guess it's a good idea to uninstall the WebDrivers as Apples drivers also support your 660Ti.

Thank you for the suggestion. I didn't see anything in that thread that helped. I did uninstall the Nvidia web driver and the same problem occurs

Looks like it is affecting real Macs too.

A beta is a beta for a reason
