Need to get to the root directory in Lion

In terminal type cd /

or

In finder, click on Macintosh HD in your favorites. If not listed you can enable it in the Finder preferences, sidebar.

 

Or open a finder window and press CMD+Up arrow until you get to the root directory

 

Nothing happens when I type the command in Terminal.

----------

Nothing happens when I press CMD and the Up Arrow at the same time. Thoughts?

 

Sure it does, it's just subtil :

Code:

host:~ user$ cd /
host:/ user$ 

Look carefully, something changed. If you want to see it better, try this :

Code:

host:~ user$ pwd
/Users/user
host:~ user$ cd /
host:/ user$ pwd
/
host:/ user$

Is the Finder window focused ? Mine goes up to the parent directory until there are no more "parents".

 

The installer file gets deleted after you run the update, you will not find it. You need to extract the installer from the package prior to running it. Or...

Here is one approach on how you can get yourself another copy of the installer:

I took the liberty to highlight the important parts. To get to root:

1) Go to Finder. (it's the smiling blue/white icon that's at the left corner of the dock, click on it)
2) Press Command + Shift + C. (it's a shortcut to jump to "Computer view")
OR
2 Alt) Click on Go on the menu bar, choose Computer.
3) Double click on Macintosh HD

And now you are in root.

If you want to navigate to a folder that you can't see, while you are in Finder, do:

1) Press Command + Shift + G
OR
1 Alt) Click on Go on the menu bar, choose Go to folder...
2) Type in the folder's name. ("lost+found" or something similar)
3) Press Enter
