Hidden files & folders after executing Killall Finder command As the picture depics some of my folders turned grey after I executed Killall Finder command. For your information, I run a macOS 10.14.6.
Do anyone know what this means, and how to get it back to normal again?

Thank your for your time

They're hidden files &amp; folders.

Since Sierra you can toggle visibility simply using  Cmd ⌘   Shift ⇧   .  [period]

Prior to Sierra you would need to toggle visibility in Terminal or by script &amp; then kill the Finder to make the changes register.

See How to show hidden files on mac without Terminal for the scripted method.
