The one thing Apple is missing from the Finder toolbar is a damn up button. Makes it difficult to use. People have said you cannot add one.
People are wrong.
But it’s not that easy. We are 1337 h4x0rz and can do it, though.
As with all such 1337 whatever, we are going to use a GUI application. So, first, open Automator. We want to create a new application. Scroll down to where it says, “Run Applescript” and drag that over to the right.
Then delete whatever code is in there and paste in this code:
tell application "Finder"
tell front window to set theFolder to target
tell front window to set target to parent of target
tell front window to select theFolder
end tell
Save it as an application in your “Applications” folder. Don’t forget to choose an icon. What fun is it without that?
Now we have to actually add it to Finder (make sure you give it permissions to run).
To add it to the Finder toolbar, we’ll drag it to that location while holding the “Option” and “Command” keys. On a Windows-focused keyboard — which is what I use — these are the “Alt” and “Windows” keys
Woo. Now you have an up button on your Finder toolbar. Makes it 80% more usable. Not too bad, right? And they said it couldn’t be done. 😉
