KristynaB76,

We appreciate you answering those questions for us.

To help isolate this issue a little more, we'd like to see if the same issue happens in safe mode. You can find more information about using safe mode here: How to use safe mode on your Mac

If the issue doesn't happen in safe mode, please check out the "If the issue doesn't continue in safe mode" part of the above link.

Thank you!

Hello KristynaB76,

We understand that some folders are showing an "Out of Space" message despite having storage space left, and we want to look into this with you.

"The Out of Space status icon indicates that the folder or file can’t be stored in iCloud because there isn’t enough iCloud storage." More about that here: Get file, folder, and disk information on Mac

Since you appear to quite a bit of iCloud storage available, we want to check into this further. To help do that, we'd like to ask a few questions.

1. When did you first notice the "Out of Space" message? Were any changes made to your device before that issue began?
2. Which macOS version is your Mac currently running? Find out which macOS your Mac is using
3. Do you run into the same behavior after restarting your Mac? Log out, sleep, wake, restart, or shut down your Mac

Thanks!

I'm encountering the same issue as KristynaB76.

The issue persists, and locks me out of documents, and renders me unable to save documents to own computer, as it says there is not enough room on iCloud, though my computer has plenty of room. It is locking me out of access to critical documents when I need them, and doesn't allow me to save the files onto my actual hard drive. Please tell me and KrystinaB76 there is an option to turn this off, and return all of the files safely from iCloud to the computer's drive.
