In Systems Preferences/Security & Privacy/General there is a message "System software from developer "Legacy Developer: JMicron" was blocked from loading. Can anyone explain this to me. And who is JMicron and should this be allowed to be on my Mac. I assume that it was blocked for a security reason? Is there anything to worry?
MacBook Pro 13”, macOS 10.14
By default Mojave blocks unsigned kernel extensions. Look for them in /System/Library/Extensions/
Specifically, it is probably this one:
/System/Library/Extensions/JMicronATA.kext
If that's the one, it's very old. Probably more than a decade.
Is there anything to worry?
No. It's not loaded, and is doing nothing.

Thanks so much for the info. Should I delete it?
It's really up to you. If that's the file in question it does literally nothing and occupies an insignificant amount of disk space. In my opinion it's not worth the effort to even look for it.
Is "Legacy Developer: Jmicron" a security issue for Mojave?
