From 5 November 2026, Backdrop 2.10.2 and earlier can no longer download wallpapers from the Backdrop library. If a download fails or you see a "Permission denied" message, your copy of Backdrop needs an update.
Wallpapers you've already downloaded keep working. Nothing on your Mac is removed.
How to update
The update is free.
- Open Backdrop.
- Choose Backdrop › Check for Updates and install the update.
- Reopen Backdrop and download wallpapers as usual.
You can also download the latest version from cindori.com/backdrop/download and replace the copy in your Applications folder.
The current version of Backdrop needs macOS 15 Sequoia or later. If your Mac runs an older version of macOS, update macOS first in System Settings › General › Software Update, then update Backdrop.
Why this is changing
We made this change to protect the Backdrop library for the customers who pay for it and the artists who create it.
Common questions
Will I lose the wallpapers I already have?
No. Wallpapers you've already downloaded stay on your Mac and keep playing, even on an older version of Backdrop.
Does the update cost anything?
No. Updating Backdrop is free, whether you have a license or use the free version.
My Mac can't run macOS 15. What can I do?
The current version of Backdrop needs macOS 15 or later. If your Mac can't run it, your current version keeps playing the wallpapers you've already downloaded, but it can't download new ones.
I updated, and downloads still don't work
Make sure you're signed in to iCloud on your Mac, because the Backdrop library needs it. See Backdrop not showing content in browser. If downloads still fail, email us at support@cindori.com.
