Q: 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).

I had this problem, and may have found a solution.

Before finding this thread, I downloaded a PDF to my iBooks from Dropbox and got the warning "your iCloud is full...blah blah". It added the PDF nonetheless. After checking, it shows I have 171GB of space in my iCloud storage.

After reading this thread, I decided to click on some preferences. I have found most problems we have are in the settings.

I clicked on iBooks(top bar)-Preferences-General(pop up window), then on the bottom there is a box: Reset Dialog Warnings [Reset Warnings].

I clicked it, then downloaded another PDF and I got no warning.

Hope this helps.

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.
