Can´t upload to iCloud folders or files made on my Mac

Are the folders on your Mac inside Desktop or Documents?

Or, are they in one of the iCloud app folders?

Otherwise, they are not sync'd with iCloud.

Can you provide some basic examples of where you are making changes that don't update?

Is there enough space. An unfinished pie indicates it hasn’t finished uploading. I’m not sure what you are describing with the “fuzzy” or “dotted,” but it sounds similar.

Sometimes the only way to fix iCloud is to sign out and sign back in. Since you plan to keep everything on iCloud, don’t save a copy on your Mac.

My iCloud Drive is active.

I put all my user created folders and files directly into the default iCloud Drive folder in Finder's left pane. All files and folders are uploaded as expected, but if doing this initially the process may take hours ... several hours if you have a lot of data. Sometimes it's a good idea to wait overnight.

Even if only uploading changes and totally new files, the process does not take place instantaneously.

On your Ventura Mac open System Settings->Intent Accounts, iCloud , "Mange button' to see if it is turn on to upload!
