So, I have this app for my eReader. It's Sony Reader and it's disgusting. I hate it. It's so useless, and it messed up my Sony account. So I uninstalled (delete from Applications) it and tried to reinstall it to make a new account, but it retained my previous login info. I looked online and somewhere said to use this command sudo /Library/Reader\ Library/uninstall-ReaderLibrary.sh to uninstall it completely, but the command wasn't recognised. Another one I tried said it wasn't recognised. Now I know it can be unsafe using the terminal, but if the commands weren't recognised, then surely I couldn't have messed anything up, right? And does anyone know how I can uninstall it properly? I get lost trying to do it through Finder.
