iTunes hangs at "Step 6 of 7. Importing photos" Everytime I connect my iPhone (4 or 5) to iTunes (v. 12.0.1.26), it begins syncing but hangs on step 6 of 7, "Importing photos".
Quit iTunes
Delete ~/Pictures/iPod Photo Cache (may or may not exist)
Go to `~/Pictures/iPhoto Library
CTRL+click > Show Package Contents
Delete iPod Photo Cache inside the library 
Try syncing again.


Worked for me.
