We have heard from several folks with issues using Adobe applications with latest OSX release.
Adobe has identified the issue and there is a temporary fix.
Loks like between Apple, Nvidia, and Adobe somebody dropped the (metal) ball.
Note that this has nothing to do with MacVidCards or our EFI roms or cards. The issue also occurs on EVGA GTX680 Mac Edition cards and GT750 cards in Macbooks.
Will update when a better fix is out.
UPDATE: New Nvidia Web Driver on our driver page.Can someone report if this fixes and allows Metal to be used?
