Mavericks update – 10.9.3 details

Last night Apple released a new ‘point’ update to their Mac OS X Mavericks Operating System, taking the latest version from 10.9.2 to 10.9.3. The details of this update are below.
Now it has been reported that in some cases this update removes the Users folder on your Mac (/Users). What is actually happening is in some cases the folder is being hidden, not removed. It is still present and can be accessed using the method below.
The main problem with this update is that this behaviour (namely, hiding the User folder) appears to be inconsistent and currently a pattern has not been found. Out of the four Macs we’ve updated in our office, two now have a hidden User folder and two do not. Despite this, all four continue to operate fine and you should not worry if this does / does not happen to you.
However, as always, ensure you have a working backup BEFORE you run updates in case the worst should happen and the update is incompatible with an Application you use.
Accessing your User folder if it is hidden 
1) In the Finder Menu Bar, Click “Go” then “Go To Folder…”
accessing folder 10.9.3
2) In the new Window, type “/Users” and click “Go”.
type users
3) This will open a new Finder window showing you the contents of the Users folder.
open new finder window
Update: No word from Apple, but:
1. Turn off Find My Mac. It only affects Macs with this turned on.
2. Run these commands

sudo chmod 755 /Users
sudo chmod 755 /Users/Shared
sudo chflags nohidden /Users/Shared
sudo chflags nohidden Users

Don’t turn it back on again.
Update 2:
Apple have now released a new small update, iTunes 11.2.1 to fix this issue.
