===== Fix app do not open =====
Some apps installed with //brew cask// require some Apple verification and decline to start.
Check app attribute:
  xattr /Applications/Chromium.app
If it says "com.apple.quarantine" - this is our case. To fix:
  xattr -r -d com.apple.quarantine /Applications/Chromium.app
