OS X 10.9.3 Bug Hides '/Users' Folder for Some Users [Updated]
The /Users folder is a top-level folder that contains the home folder and personal files for each user on a Mac. It's not clear why only some OS X users lose access to the /Users folder, but the inability to browse this folder could be problematic for some Mac owners affected by the glitch.
A range of solutions for the bug have been suggested with varying degrees of complexity, with perhaps the simplest noted by Kirk McElhearn and Chris Breen of Macworld:
Launch Terminal (/Applications/Utilities), enter "sudo chflags nohidden /Users", and press the Return key. You’ll be prompted for your user password. Enter it, press Return again, and the Users folder will be visible as it once was.This solution is not, however, a permanent one, as the issue will reappear if the machine is restarted and the fix will need to be applied again.
Breen goes on to outline a more permanent solution that involves creating an AppleScript for running the Terminal command and saving it as an application to run at login.
Another recommendation comes from The Loop's Dave Mark, who suggests creating an alias for the folder that will remain accessible even with the folder itself hidden.
For a more permanent solution, [after manually navigating to the hidden folder] control-click on the /Users folder and select Make Alias from the contextual menu that appears. Though the /Users folder will become hidden again when you close your Finder window, the alias will stick around.For many users, the bug will not have a significant impact on their Mac usage, as they can still access their own home folders through shortcuts in the Finder sidebar. Consequently, some users who are not inconvenienced by the bug may prefer to simply wait for Apple to address it in a future update.
Update 10:30 AM PT: As noted by MacObserver, the issue may be caused by a combination of iTunes 11.2 and Find My Mac rather than OS X 10.9.3. The site tested each update released yesterday and found the /Users and /Users/Shared folders only disappeared after iTunes 11.2 was installed on a Mac with Find My Mac enabled.
