where is your config file located? try to run an instance with mongod --config /path/to/config/mongod.conf. if it has fork enabled in it, comment that line before starting. doing this will start the server in the current terminal and will print errors to screen. it should exit immediately, if not use “ctrl+c” (cmd+c?). copy that log and share here. (don’t forget to format)
