I am trying to rename a whole bunch of photo files all at once. On a PC, all I do is highlight all files (using shift key, as in Mac), then right click and select "rename" (don't seem to have this option in Mac). After selecting "rename" the name of every file is then highlighted and once i change the name of the first file (say "Vacation_2010") then the entire file automatically changes name to "Vacation_2010_(1); Vacation_2010_(2).... and so on. It takes about 20 seconds and I can rename all my files. HOw do i get the same result using my new MacBook?
