There have been a couple threads asking for the best Mac apps, and Teslanaut has compiled a short and sweet list of some good apps. I think it's time to make one thread to end them all. So post your favorite Mac apps, and we'll make a huge list for reference. My favorites are: Firefox RC1 ByteController - iTunes controls in the menubar + hotkeys aLunch - App launcher in the menubar. Similar to a Windows start menu. Quicksilver - hotkey app launcher Adium - Instant messaging client Skitch - Screenshot taking, editing, and hosting app. VERY powerful. Hear - Turns all system and application sounds into rich, high-quality 3D surround sound. Amazing application. MS Office 2008 - I'm a windows convert. Growl - a notification popup system that gives notifications in the bottom right-hand corner when an iTunes song changes, an im buddy signs on, a download is finished, and even when FF3 finds an extension update. So, post your best apps. Try to post a description as well as the app name.
