In this post I am going to share – How you can show contact list in Messages app in OS X. I know we all expect this to be there by default, but surprisingly it’s not!
Well, you can toggle buddy/contact list by simply pressing command + 1. Alternatively, when the Messages window is active, simply click Windows and choose the buddy list which you want to show.
Messages group buddy list of different account into one window, but if you want to show them separately just goto preferences and uncheck the option which says – “Show all my accounts in one list”
So you can toggle the multiple buddy list by pressing command+1 , command + 2 and so on, depending on number of accounts you have added to the app.
Hope that helps.
