Remember that discussion about the hidden (for some) /Users folder that came with the release of OS X 10.9.3? Well, turns out the issue was really with Thursday’s coinciding release of iTunes 11.2.

Check your Mac for an update this morning. The update (to iTunes 11.2.1) restored my /Users folder to its former glorious visibility.

From Apple’s iTunes 11.2.1 support page:

Available for: Mac OS X v10.6.8 or later

Impact: A local user can compromise other local user accounts

Description: Upon each reboot, the permissions for the /Users and /Users/Shared directories would be set to world-writable, allowing modification of these directories. This issue was addressed with improved permission handling. For information on the general content of iTunes 11.2.1, see http://support.apple.com/kb/TS5434.

The text “A local user can compromise other local user accounts” struck me as interesting and at the core of why this change was made in the first place.
