Few and the far between, Mac IM clients must push the envelope year after year in order to remain competitive in attracting Mac users. The Reader's Choice Awards title for Best Mac IM measures the overall user satisfaction, efficiency and design of Mac IMs.
Past winners of the Best Mac IM award include Adium (2008) and Yahoo! Messenger for Mac (2009). This year's nominations bring those two rivals head-to-head again, alongside two veteran IM clients' Mac versions and a popular VoIP application.
