    FYI on Nvidia Web Driver Updates:
    Users of Nvidia's web drivers should know that new OS updates (versions or later build numbers after Security Updates) break any currently installed Nvidia web graphics driver. I'd switch to the default Apple driver and reboot before updating, if your card is supported with the default drivers. If not, wait for a Nvidia driver update. (Some non-Mac EFI cards are not supported by default OS X drivers.)
    Of course have a current backup (and if possible, a Clone) of your boot drive before any update.
    (As usual, I'll post download pages for Nvidia updates when spotted.)
    Update: See Jan. 24th news for new graphics drivers for macOS 10.13.3, 10.12.6 and OS X 10.11.6 builds with Security Update 2018-001. Also a new CUDA 387.128 update. (For later macOS/OS X driver updates, check the Video topics page, Mac Nvidia Driver Downloads page, and recent site updates.)
