Beginning with Mac OS X 10.7 (Lion) the Library folder folder is hidden by default. As a developer there are times that accessing this folder is necessary. For example, ~/Library/MobileDevice contains folders for iOS applications, devices and profiles – there have been any number of times I’ve found it helpful to clean up the profiles folder so Xcode isn’t overloaded with options for code signing.
To reset the Library folder so it is no longer hidden, from a terminal enter the following:
chflags nohidden ~/Library/
Should you choose to send the folder back to a hidden state:
chflags hidden ~/Library/
Go To Library Folder
On a similar note, here are a few ways to get to the Library folder:
– From Finder hold down the Option key when viewing the Go menu, the Library folder will be shown.
– When Finder window is active, press Shift-Command-g and enter ~/Library in the dialog.
– If you are in a terminal, you can enter: cd ~/Library.
All three options above will work regardless of whether or not the Library folder is hidden.
