A short notice to all nVidia users here. The standalone updater for macOS 10.12.1 from Apple's download area results in build version 16B2657. However the App Store update to macOS 10.12.1 results in build version 16B2655. At the moment the nVidia Webdriver 322.214.171.124f01 for 10.12.1 is build to match build version 16B2655. So if you depend on using the nVidia Webdriver you might want to use the App Store to update to macOS 10.12.1 until nVidia addresses this issue.
