How to fix missing books in iBooks after MacOS Sierra update
After MacOS Sierra update the following happened:
1. Adding books into iBooks no longer synced across my idevices.
2. Estimated 50% in some cases in each Collection of my books on iBooks mac have disappeared
3. Books are intact and complete on iPhone and iPad, but no longer link with my Mac library
4. The new iBooks no longer have the updated icons for iCloud. No longer sync or upload to iCloud.
5. I can still download the books on iCloud on my iDevices when I need them. Cloud icon still available on each book for downloading if needed.
So my conclusion is that the books in the iCloud library that was previously synced from my Mac is still in the cloud.
Until the MacOS Sierra update, it lost connection to iCloud, and also have lost my books too, no idea why.
My concern is that if I reinstall MacOS Sierra, the Mac will update the iCloud library and also wipe the books that are missing on my Mac but still on iCloud.
Any suggestion as what I can do to get it syncing again, get my books back to my Mac and be able to sync again on all devices?
Thanks in advance!
