I'm sharing my MacBook's internet connection wirelessly with a PC, and every time I startup my Mac, I need to go to System Preferences>Sharing and uncheck then recheck the Internet Sharing box again just to re-activate the internet sharing because I don't know why my MacBook isn't sharing the connection at startup since the box is already checked.
That's why I'm looking for a way to automate this action at startup so I don't have to keep repeating doing this.
