I have the Oracle Instantclient installed (PHP needs it for the oci extension to work), the install directory is /opt/instantclient_19_3 and every time I log in after a reboot I get the following error messages which read translate to

libclntsh.dylib.18.1 cannot be opened because the developer can't be verified. libclntshcore.dylib.19.1 cannot be opened because the developer can't be verified

I had the same errors popup when using Terminal and Hyper but since I've allowed those apps full disk access everything works fine. Still, after logging in I get both error messages, so I assume something needs permissions but I can't figure it out. Any hints?

This should do it!

System Preferences -> Security & Privacy -> Developer Tools

White-listing one-by-one

While launching your non-verified app keep your System Preferences -> Security & Privacy -> General open. You can whitelist executables and libraries along the way. They will pop up in the general tab.

  • Hyper, VS Code and Terminal are listed and checked.

  • @mazedlx Are they listen under Developer Tools? Nov 4, 2019 at 9:45
  • Yes, they all are.

  • The error only shows up after login. And all the „usual suspects“ are showing up in Developer Tools.

Found it!

The solution is to open the General tab in security and wait for the libs to show up and allow them there.enter image description here
