Mac forgetting my desktop background - iCloud uploading
I have my desktop pictures saved in a folder on my desktop (example below).
The problem is, sometimes, when I log in to my computer after having it restarted or shut down, all of my desktops show the default wallpaper (in my case the sunset Catalina one). The first few times I was very confused but I later managed to narrow it down to the small download cloud that appears next to the folder that holds my desktop pictures. The only way to get the pictures back is to click the cloud icon, wait for the pictures to download and restart my computer; only then I see again my pictures back up on all my desktops.
I am wondering if there is a way to stop this from happening.
