Setting environment variables via launchd.conf no longer works in OS X Yosemite/El Capitan/macOS Sierra/Mojave?

Question

It looks like the launchd.conf does not load my environment variable anymore. Has anyone else noticed that?

Is there another solution to permanently set

Answer 1

The solution is to add your variable to /etc/profile. Then everything works as expected! Of course you MUST do it as a root user with sudo nano /etc/profile. If you edit it with any other way the system will complain with a damaged /etc/profile, even if you change the permissions to root.
