Can't delete apps in itunes
Im using a MacBook Pro fully up to date. I have Apps I don't want anymore. Some are real duds. I have deleted them from my device. They are marked as needing to be installed. I want to delete them from my MAC but cannot get them to delete no matter what. They are taking up space that I don't want being used. I have seen posts that answer the question for Windows but not for MAC. How does one accomplish this seemingly simple task. Pressing any of the keys and delete does not do it. So what does?
MacBook Pro, OS X Mountain Lion (10.8.2)
