This update: - Improves 4K display support on Mac Pro (Late 2013) and MacBook Pro with 15-inch Retina Display (Late 2013) - Adds the ability to sync contacts and calendars between a Mac and iOS device using a USB connection - Improves the reliability of VPN connections using IPsec - Resolves an issue that prevented Font Book from installing PostScript Type 1 fonts - Improves reliability of copying, editing and inspecting permissions of files on an SMB file server - Improves reliability of network home directories - Improves stability when installing configuration profiles - Improves login speed for users in Active Directory groups - Includes Safari 7.0.3
I love how when you go to the official update statement the Safari 7.0.3 line is in a smaller font. Just makes me giggle.
This brings me to a kind of interesting topic, at least for me. How do your enforce Software Updates? How quickly do you push them out to your users? What kind of policies do you have in place for Software and OS Updates?
