The 30.1(2025.1.Beta2) renders correctly in my tests on OSX 14.x. We'll test it on 15.x further.
On the other hand, can you please try this exported scene in the 2025.1.Beta2 Standalone and let me know whether the displacement renders there? Thanks!

You can find it in the latest 28.x and 29.x versions.
The Global version is designed for users who want to use a single imager/post-process for all cases(like C4D). But it's not enabled by default for backward compatibility.

The [+] button adds the default node if Octane Standalone specifies the default type. If there is not a default node type, it shows a menu containing all available nodes.
You can always invoke the menu by "SHIFT + Click".

This will be fixed in the coming versions.
