Lockscreen Picture
How do you change the lock screen picture in Catalina on the Mac? I was told they took this feature out of the Catalina version. And there was all kinds of complicated ways to do that online that didn't sound safe--are there any easier ways? Like if you have a picture you want you can't just change it to photo.heic and drop it into Go/System/Library/Desktop Pictures because it won't allow you to add any pictures to that folder.
