daily devops problems solved and explained

You might have gotten this error saying

“.. can’t be opened because it is from an unidentified developer” / “.. kann nicht geöffnet werden, da es von einem nicht verifizierten Entwickler stammt.”

Instead of turning off the security feature GateKeeper entirely which is suggested by most websites on this topic, you should rather make an exception for those applications that produce this error but you got them from a trusted source!

This is done fairly simple:

• Click on the Spotlight search in the upper right corner and search for “Terminal”, open it
• In the new window enter
  cd /Applications
  sudo xattr -r -d com.apple.quarantine CrossFTP.app
• When asked for you (user account) password, enter it
• Your done !
