However, it does not seem like hiding the /Users directory is an Apple design decision. With OS X Lion, Apple took the liberty to hide the Library folder from OS X users.
This means the folder is no longer visible when looking at the root of the hard drive in the Finder, which is inconvenient for Macs with multiple users installed. Since upgrading to OS X 10.9.3, some users are reporting that their /Users folder is now hidden. Update: The glitch may be related with the latest versions of Find My Mac and iTunes, according to testing by The Mac Observer.
