- extract zip file = open the zip file that you download into a folder on your Mac

- change to the zip directory = start the Mac application Terminal. (It is in the utilities folder in your applications folder.) This will open a terminal window with a $ prompt. Switch to the Finder and change to the directory where the files you unzipped are located. If you look at the top of the finder window, you will see a blue folder icon with the name of the folder next to it. Switch back to the terminal window and type "cd " (that's the letter c, the letter d, followed by a space - do not hit enter.) Now, drag that folder icon at the top of the finder window I mentioned before to the terminal window and drop it. This will type the actual folder path next to the "cd " that you typed before. Now, activate the terminal window if it is not the active window and hit enter. You have now changed to the zip directory.
then drag the folder into the terminal window again followed by run.sh should look something like this
/Users/nick/Downloads/LG_Esteem_Root_v2_Linux_OSX/run.sh
then press enter and enter again to root
