In Finder, go to the Applications Directory, find the “EVE Launcher”
Rightclick on it, open its info-window (for instance, rightclick + “get info”).
There you should find “Where:” the Launcher is.
With that information, go to Terminal again, you can also copy it directly from the info-window (for me it is under “General” in the 3rd line, but it may be different for you)
“cd” is for change directory
now, in Terminal, write
cd “paste” (so either type exactly what is in the info-window under “where” or simply copy+paste)
(if you type manually here, do not forget the leading “/”)
This is should mean you are in the Application-folder of your mac.
“pwd” and it shows you the directory you are currently in
now, if you type “ls” (lowercase L, lowercase S), it should list the programs in that folder.
you should see “EVE Launcher” there somewhere
cd EVE (and then press “tab” it should auto-complete)
then “pwd” again and tell me where you are
if you are in something called …/EVE Launcher…/Contents/MacOS/ you are where you should be
don’t forget the leading . and / otherwise nothing will happen
