Q: ipad air/macbook air intermittent connection

Hi all, I'm hoping to get some help diagnosing a problem.

 

I have an ipad air running iOS 9.3.1 and a macbook air 2014 running el capitan.

 

I can charge the ipad from the wall no problem and from the mac boot loader (by pressing alt at start up). Because of this I don't think it's a problem with the lightning port or cable.

 

When I boot into el capitan and plug in the ipad via the lightning cable it just keeps connecting and disconnecting rapidly. This means I can't test my apps on the ipad as it isn't connected for long enough. Charging from the mac would be nice too.

 

This is the console log that may be of some use:
