Skype put Mac users more on parity Monday with the launch of Skype 5.3. The new update brings HD video calling to the Mac for the first time. Those with a FaceTime HD camera in a 2011 iMac or MacBook Pro, as well as those with higher-resolution add-on webcams, can get a major boost to resolution in two-way conversations. Both sides need about 1.5Mbps of bandwidth to keep a smooth connection.
