iPhone 5 will not sync Photos albums on iMac
I have the most current version of iTunes, OS X and IOS, although this problem has occurred for the last few years/versions of all. Maybe since I downloaded Photos, iPhoto seemed OK. When I create an album in Photos it usually will not upload or if it is uploaded it will not sync when new photos are added to the album. I say usually because about 10% of the time it will work. I have tried reinstalling iTune and deleting all photos from my phone, both with limited success only to have it revert back again. This is so frustrating because I use a DSLR and do edits in Lightroom and I like to add the finished products to my iPhone. Currently my phone is updating and it is hung up on step 5 of 6, importing photos. This will stay like this until I walk away. Sometime I'm told the library is unavailable. Any settings or fixes would be so appreciated as I am at a loss and so frustrated.... Thank you in advance!
iMac, Mac OS X (10.6.8)
