iBooks message - iCloud storage full (but isn't)

Same problem, with 4.69Gb free space.

But it is an intermittent bug - sometimes it works OK after a restart.

I had the same problem.

The solution for me was:

1. delete everything from iBooks on your Mac
2. disable iCloud Drive for iBooks form the Mac
3. go to iBooks on the iPhone and verify that there is nothing (since you deleted everything from the Mac, if there is something delete it)
4. upload some documents from the iPhone (by opening them in Safari and copying them to iCloud)
5. try to upload something from the Mac, it should work.

I hope this works for you too.

Similar issue for me. I have only 1 account (USA), where I have everything besides iOS devices backup (free plan). I have 1,5GB of the iCloud storage left, and can't upload a PDF 4,2MB, because "there's not enough space left". Tested on Macbook Pro 13' early 2015 with OS X 10.11.6 (8,88GB out of 250GB free on my Mac).

Hi there,

Having two accounts should not make a difference, as each account are accounted individually.

My guess is that an iCloud full storage (but isn't) error is not necessarily related to the iCloud storage issue!

There must be a bug somewhere, as even if it asks you to upgrade your iCloud storage account and still have plenty of space in your iCloud drive the problems doesn't comes from there...

I had the same issues, downloading e-book and getting that iCloud full storage issue. I realized that my two other devices, iPad and iPhone where full but my MacBook Pro wasn't. I tried freeing you some space into the iPhone and iPad and suddenly the iCloud storage issue disappeared...

I'm not sure it's gone work with you, it did with me it's worth the try!

Nope not related to the amount of books, but rather to the physical space you have in your devices... I freed up space in my devices and the iCloud storage error disappeared... Apple must have a bug somewhere it looks like e-book does not make the difference between available space in iCloud or on the devices...

I can't agree with it. None of my devices is full in terms of physical space. What is more, all of them have more than 20GB of free space (the PDF I've tried to upload was below 1MB).

I am having the same problem. I was in the Beta program with Sierra and I was getting a similar message with my iCloud account. Telling me that I didn't have enough space when I had 490GB left. Now iBooks is telling me the same when i cloud is reporting 540GB left. It might be an iCloud issue.

This problem occurs when your PDF or your ePub is damaged. That's the error message from iBooks for that problem (I know, not exactly self explanatory...)

The way to fix that is to :

1) delete the iBooks copy of your document (PDF, ePub,...)

2) download Calibre (eBook manager, free). Don't know if I'm allowed to post external links but, whatever, Google "Calibre" and you'll find it very easily. Straightforward interface, don't worry. Free and no adware or whatsoever.

3) once Calibre is installed, you open your "damaged" document in it and you ask it to "convert" your ePub to ePub or your PDF to PDF. Yes, convert it to the same format !

4) it usually takes less than a minute per document to process and puts the output in a folder called "Calibre Library", at the root of your user folder (~/Calibre Library). You have a subdirectory with the name of the author or document creator. You'll find in it a copy of the original document AND a processed copy, corrected.

You can now open that corrected copy in iBooks and you shouldn't have that infamous message about your iCloud being full anymore.

This worked for me! Thanks a million.

I Have the same problem. I have 49 GB empty space by iBooks is showing iCloud space in full.

Weird, it appears as if the iBooks has started storing its data on the store account and not on the account's iCloud Drive account. Once I sign out of the store account, all current books disappear.

Ok found a fix I think.

Inside the iBooks.app on Mac: If you sign out of your store account (account A), sign in to your iCloud account (account B) it'll pop up saying your books are synced with your store account (A), and ask if you prefer to sync with your iCloud account (B). Click sync.

Then logout of account B and log back into account A. Then it'll ask the same question again, this time saying it syncs to account B. Click "Don't Sync".

Now add a new book and see if you can find it under ~/Library/Mobile Documents/iCloud~com~apple~iBooks/Documents.

Worked for me, it now syncs books to my iCloud account.

This seems to have been broken for ages and it is still broken. Frustrating, just plain doesn't work on desktop. Have to upload books via mobile device for it to sync. I get the same false - icloud storage is full, upgrade to sync book...

This is still an issue in Sierra. Has Apple been looking to their forums lately?
