When I go to sync clips in Premiere Pro it will only sync two clips. It won't sync multiple clips at once like Syncaila does. If this could be fixed it would be a game changer. I am working with a MAC

How are you trying to sync these clips? 

If you are trying to select multiple adjacent clips by selecting them in the timeline right-clicking and choosing synchronize you are correct. It will only synchronize single clips stacked up. For multiple clips, you need to use create multi-camera source sequence. It would be nice if there is a Syncalia style sync but there is not.  

You might want to try syncing it as a multi-cam sequence.
