Many affected Skype users who were unable or unwilling to update to OS X Mavericks in order to get the latest Skype builds took to the Skype forums to voice their complaints. What the company didn’t say, however, is that some old platforms require these old versions, meaning some Skype users are essentially being dropped. In June, Skype announced plans to retire old versions of its Windows and Mac clients “over the next few months,” and then expanded the move in July to “all platforms” along with another vague “in the near future” timeframe.
