VERY slow sync (hours!) for pictures via iTunes for Mac since last Mojave and iOS updates (3/2019)

Same problem, submitted via link you shared, thanks.

Still having same problem a month later. My issue is precisely the same as yours.

Apple, please wake up and help !!!

That’s what I was starting yesterday hoping it might solve the issue for now, thank you for the update!

same with me: after update still the same problem. It's very sad that there is no comment or help from Apple...I informed them weeks ago about the problem...

Sorry. Duplicate post removed.

Thanks for this workaround. Works perfectly!

My 5K iMac is running Mojave 10.14.4 After updating my XsMAX to iOS 12.2 image sync (using iTunes 12.9.4.94) from iMac to iPhone is slow to the point of being unusable. I have one iPad Pro that I haven't yet upgraded to 12.2 and the sync works properly with the same iMac. This suggests the problem is with the interaction of iOS 12.2 and iTunes 12.9.4.94, not with Mojave.

I'm a business user, and Apple's increasingly buggy updates are causing me to consider abandoning the entire enviroment. They're no longer producing adequately reliable machines. Too bad, its been a long, productive run.

In addition to hanging for hours when trying to sync, when it finally completes there are photos /videos that have not been copied across in several albums (the number of photos shown on iTunes does not agree with the number of pictures on the iPad/iPhone ) historically when this occurred you would re-sync and wait for the final pictured to be moved across but this no longer happens. After waiting overnight for the final pictures to have been identified and copied across I now find the picture count to be the same and the photos to still be out of sync.

I am copying the same albums and pictures to my iPhone X and to my iPad Pro but it doesn’t even copy the same photos (And leave out the same photos) on the 2 devices i.e. it copies 399 photos from the folder on my Mackbook Air to my iPhone and 595 photos to the iPad Pro - the same folder ......

Correct: Only thing that helps is

1) deleting the iPod photo cache

2) sync iPad or iPhone with unticked "photos" box first

3) than tick "photos" and than starting sync

Unfortunately that works only once. If you want to update again you need to run through the whole process again....

Now I switches to the photos-app.

The problems are with the sync of the "filesystem-photos", so I tested it with the photos-app. And the sync is ok! So I imported all of my 28.000 photos into the app, created some albums and, last but not least, I activated iCloud-photos.

Because of a sync-problem I changed the complete process of the organisation of my photos. But it works and I'm happy.
