Q: i cant get my photos to sync from i photo on my mac book to my new i phone 6

If the photos are in iPhoto you can use iTunes to sync them to an iPhone: Sync photos to your iPhone, iPad, and iPod touch in iTunes - Apple Support

Another option is Photo Stream: My Photo Stream FAQ - Apple Support

If the photos are in the new Photos app in Yosemite 10.10.3 you can use iCloud Photo Library to automatically have all of your photos on both your Mac and your phone as well as at iCloud.com. This is the best option if you want all new photos taken on your phone to go to your Mac and any new photos added to your Mac from sources other than your phone to automatically go to your phone as well. iCloud Photo Library FAQ - Apple Support
