I've only had my Mac for about a month, so I'm relatively new at this. I'm trying to install Capti Narrator. The download file is a .pkg file. Everytime I try to open it, the Mac thinks it's a plain text file and opens it in Text Edit. I've tried the "Open With" option, but I can't figure out where the installer is fore it to open that way. The team at Capti suggested I re-download the program by right-clicking on it and using Save As. I did that, and nothing changed; it still sees it as a text file that wants to open in Text Edit. Any suggestions?
