I tried to install the Intel Power Gadget and I got the following error. I am on the latest stable release of MacOS High Sierra on a fairly clean/new install. Is this something known? EDIT: typo fix
Ok, a solution was found.
A better message about allowing Intel Power Gadget to be loaded in the Security&Privacy preference panel should be added.
