Apple made the user library folder hidden by default with the 10.7 and later releases of Mac OS. If it's necessary to access these files for Adobe-related troubleshooting, use one of the following methods to make the user library content visible.

Method 1

In the Finder, choose Go > Go To Folder.
In the Go To Folder dialog, type ~/Library
Click Go.

To the top

Method 2

Hold down the Alt (Option) key when using the Go menu. The user library folder is listed below the current user's home directory.

Note: After you open the Library folder, you can drag the Library icon from the top of that window to the Dock, Side Bar, or toolbar. That way, it's readily accessible.

Method 3

The following method makes the user library folder permanently visible. 

Note: Adobe recommends that only advanced users use this method.

Launch Terminal from Mac HD > Applications > Utilities.
From within Terminal type the following command and press Return:

chflags nohidden ~/Library
Enter the system administrator password, if prompted, and press Return.

Note: The System administrator password is not visible as you type it.  

Close Terminal for this change to take effect.
