Not-so-frequently Asked Questions

Which version of OS X is it compatible with?

I've tested it on OS X Sierra 10.12.1 and it works fine. As long as the way desktoppicture.db is used doesn't change it should keep working on future releases. I don't know if it is compatible with older versions. Try it at your own risk.

Does it work with multiple monitors?

Yes.

What happens if I mess up my desktoppicture.db?

Delete it and restart Dock. A new file will be created and the backgrounds will be set to default.

rm ~/Library/Application\ Support/Dock/desktoppicture.db
killall Dock

Does it work with bash?

No, but the SQLite calls are still valid. Just change everything else in the script.
