XP_2003 has posted some screenshots of a beta version of MSN Messenger 4 for the Apple Mac. Although there haven"t been any major changes from previous versions, XP_2003 has noted that there have been a lot of icon changes. If MSN Messenger 4 is released with features like it has in beta then Mac users will find themselves still behind the PC version which has more advanced features and simple customisation options like personal display pictures and custom emoticons. Microsoft"s failure to update its Mac Messenger client will surely disappoint Mac users.
