Used to be, your Home folder showed folders labeled Documents, Pictures, Movies, Music, Desktop, Public, and Library. (This is “your” Library, the so-called “user Library. There are others but this is the one we’re talking about now.) Your user Library is full of very important stuff that shouldn’t be messed with unless you know what you’re doing, so starting in Mac OS 10.7 (Lion) Apple hid it from us. Generally speaking, that’s OK, but sometimes you have to get into your user Library to delete a preference file or do some other maintenance. There are various ways to make your user Library folder visible, but none as simple as this:
1. Click on the Desktop to switch to the Finder, the open up your Home folder (⌘-Shift-H will do it)
2. Go to the View menu and choose Show View Options (or ⌘-J, as my friend Dave always reminds me)
3. Check the box at the very bottom and “Show Library Folder.” That’s all there is to it. See below.
This only works if you’re looking at the contents of the Home folder (Step 1 above) when you do View/Show View Options. If you want to show the Library folder on an as-needed basis, try holding the Option key and going to the Go menu. You’ll see “Library” there. Checking the box to “Show Library Folder” in the View Options for the Home Folder puts the Library into the Go folder permanently (no need for the Option key).
