IBooks IOS 8 will not sync all books

Another part of the problem, snapshot right now.

iTunes says 'copying 603 of 2043' then it says 'cancelling sync'

But when I sync again to keep the process moving, it says 'copying x-number of 1804'. But the difference between 2043 and 1804 is 239. Nowhere near 600! So it is NOT actually copying the number it says it is. In fact, doing the calculation it is actually only syncing about 240 items each time. With 6000 items to be copied I can anticipate doing this almost 30 times. Which is absurd.

When will Apple drop the corporate silence on this issue, tell us why it is happening and how it is to be fixed?

I've put this up in a previous thread, but this is a classic bug which Apple has elected NOT to fix, not for several months, maybe not ever, and it's linked to the USB download of thousnads BOOKS only--music and videos will still download thousands of titles or a 100GB of data.

Here's my workaround post from another thread, and it still works:

I've had the same problem Syncing lots of books (about 3,000 in my case), and it always timed out at around 250. For me it's always the same number, almost like binary 256, which leads me to believe it's a software variable definition error. And yes, you can just keep hitting the sync button after the end of every "lap" to eventually get all of them.

Anyway, I did find a workaround that worked for my iPad: instead of syncing via USB, which is usually faster, try the Books sync using wi-fi (you must go through authorization and permissions with both computer and phone/tablet the first time). In that case, over a good N network router, the remaning 2,000 books all went on all at once fairly quickly. It's apparently a USB port time-out phenomena, so make sure your USB ports are not set in "power save" mode (the default in Windows 8.1--I don't know about Mac). But still, wireless may be best in this case, which is counterintuitive considering long wireless file transfers are usually less reliable the hard-wire. Funny how an older iPhone can take hours to sync 5,000 songs and not time-out, but just 3,000 books using a lot less data dies prematurely.

I just got an iPhone 6 Plus with 128 GB, and it worked for that as it did for my two 128GB ipads (both Air and Mini).

If you cannot or will not use wi-fi, must or insist on USB, you must just ...leave iTunes on and click Sync every few hours, including watching TV which is connected directly to PC graphics via HDMI. It's like the old days when you could only copy one folder at a time in DOS 1.0--think of it as 1980s retro-computing, like cassette tapes and scratchy vinyl.

And yes, you are all right that it's "shame on Apple" for not fixing this after about a year now. I'm a software/network engineer with 30 years experience, and it's a shame on our profession. Old school folks like me would never let such cocca persist.

Help!

I have exactly the same problem. My books collection will not sync with my Iphone 6 plus (128 Gb). I work with Yosemite on my Mac Pro and have all the latest os's installed.

When I check Ibooks on my phone while syncing with my desktop, I can see the books popping up for an instance but then disappearing again. This happens also when I sync via wifi.

Only books that I bought in the Ibooks store show up (and a few others from my own collection). This is a new phenomena because it used to go perfectly. Also with my old Iphone 4.

I used to have the same problem of syncing my books from my computer to my ipad. It keeps on "cancelling sync" every 100 or so books.

I have figured out a way so that it doesn't cancel sync regardless of the number of books.

While you are syncing your ipad to your computer, make sure that your "iBooks" application on the ipad is open. That way, the books are also loading simultaneously into your iBooks application while you are syncing.

Hope this helps.

I have the same problem. I have like more or less 800 books and whenever i try to sync it, it always shows that bar that said 'copying items...' and when i open ibooks on my iphone while syncing, the item that's currently being copied shows up for like 2 seconds and then it's mysteriously gone again).

So I ended up just putting all my books in the nook app on iphone and you dont even need to sync your iphone to get all the books copied into nook because you’ll be using the File Sharing feature. How to do this:

1. connect your iphone to your computer
2. under the summary there’s the app tab, click that
3. it will show you all your apps but scroll down
4. there will be the file sharing sections. click nook. drag your books into nook documents box
5. refresh your nook app on iphone. done. And it doesn't even take forever like when you sync. You can use other apps that have the file sharing feature too, it doesn't necessarily have to be nook.

Hi, exactly the same issue with iOS 9 and iTuned 12.3, no improvement at all, even worst. My 3200 EPUB books are all in iBooks El Capitan on MBP. But the sync to iPad Air is a DISASTER! Exactly the same catastrophic issues as described before with the earlier iOS versions. Horrific! The sync process cancels after syncing between 150-200 books. The amount of books waiting to be synced seems to decrease after avery new sync, but at the end I just have the half of all books, about 1600 on the iPad and in iTunes to sync. Both the pile showing the size of books and the marking of radio button for all or marked books is jumping on and back as a lunatic and the books uncheck without any warning and keep showing different numbers all the time. I tried the trick with open iBook on iPad and the sync went this time on over the usual couple of hundred books, but in the end the the result was as catastrophic as I described. Really, what kind of extremely awful corporate policy is that to not even respond on Apples own forum to all frustrated users and buyers who payed hundreds an hundreds of dollars for these Apple products? That's us who payed your salaries! Don't do we earn some attention?

Hi all

same problem whith my iBooks and i think apple support dose not even look at our reviews or comments becouse if so they will have fixed this problem thats been their around more that a few months and it is since iso 8 so i hope they will fix it soon or should i hope that they will look at our posts

Stupidly, I upgraded my iPhone 6 to iOS 9. This means, that my Mac Pro 1,1 will no longer sync with it, as it doesn't run the latest iTunes anymore.

But this meant I had to synch using Windows 7 on the same machine.

All my books are there, all the music, everything! And no, they're not all books, most are pdf-documents on applications we write at work, created at work. Nice to have an independent screen next to the office's PC, right?

Not gonna buy a new Mac any time soon, everything seems to be working better using Windows than using Apple's own OS X...

Issue still unresolved as of 26/12/2015

Poor form Apple (but I still love you) :-P

Will try the sync via wifi as the user 4 or 5 posts up advises.
