If You want to track NSWindow live moving, it's not possible by default You’ll have to do it on your own. It's possible to get notification when NSWindow is started to drag (move) with NSWindowWillMoveNotification or ended dragging (moving) - NSWindowDidMoveNotification.
Take a look at these examples they can help You to solve live window moving problem:
1. Example:
Description: Very short category on NSWindow that makes windows post NSWindowDidMove notifications continuously during dragging (much like NSWindowDidResizeNotification behaves). Uses a secondary thread and behavior can be toggled.
