This is so annoying. I just purchased the Living Weather HD app for my new iMac but it persists on having an annoying icon on the dock 24/7 and even worse, the icon shows the current temperature outside as a little red bubble over the icon the same as Messages does when you have new messages. Very unappealing. I googled ways to remove the app icon and most said to change the .plist file for the app, but that doesn't work, I tried giving myself permission to read & write on the file but it still doesn't let me and says I "don't own this file." Any advice? I can't believe Apple doesn't have an option for something as minuscule and simple as this after all these years COME ON GUYS.
