the easiest way to Change Directory in terminal on the mac is:
1. open a terminal window by running the Terminal app in your Utilities folder.
2. type "cd " (without the quotes, and take note of the space after the 'd', it's required) but DO NOT hit return yet
3. back in finder, drag and drop the folder you want to go to into the terminal window. anywhere is fine, it doesn't have to be by your command. just drop it. terminal should type in the path for you.
4. select the finder window again if needed, and press Return to run the command. in most cases, the path will show up as a part of the prompt, replacing "~", which is unix for "home folder".
now you are CD'd to that folder, and any terminal command you run ought to know where you were when you ran it.
(SOME terminal programs are meant to run automatically in the folder the PROGRAM is located in, not where you happen to be CD'd to. but the author should inform you of this)
