IPhone won't connect to Itunes

I have read a lot of the discussions and found a lot of ways to fix this on a windows computer. The problem is I have a mac and can't seem to find a solution. So far I have tried rebooting a bunch of times and making sure iTunes is the latest version. I have also tried 4 different cables including a brand new one so that is not the issue.

Everything worked up until two days ago (both syncing through wifi and plugging in the cable).

General info

IPhone 6 iOS 9.1

Mac is on OS X Yosemite

When I go to the "about this mac" and go to system report and click usb, it says my iPhone is connected. My phone charges when its plugged just doesn't seem to want to show up on mac.

If you know any way to fix this please let me know. Thanks
