helm-osx-app-pref-folders

Folders containing system preferences. Defaults to

("/System/Library/PreferencePanes"
 "/Library/PreferencePanes"

helm-osx-app-actions

Actions for helm-osx-app. Defaults to

• Open
• Reveal file in Finder

A bug with open -R?

The "Reveal file in Finder" action usess open -R to reveal files.

However, if you've marked multiple candidates, "Reveal file in Finder" works for only the last candidate. It seems a bug of Apple's open(1), the manual page says

-R Reveals the file(s) in the Finder instead of opening them.

but

touch foo bar && open -R foo bar

reveals ONLY bar.
