Never had a message like this with any other software.

MOI3D wants to control my machine!

Hi pauland, I think it's from some new security mechanism in Mojave that is probably overly sensitive and needs to be tuned up by Apple.

Does it come up all the time or does it go away once you give it one ok?

The next MoI v4 release may avoid triggering that message, v4 has been largely rewritten with simplifying the Mac version as a major goal. V4 is now a native compiled Mac program while v3.2 uses this pretty complex system called Wineskin. It might be something in Wineskin that triggers it, I don't know for sure.

There are a lot fewer layers of stuff in v4 and hopefully that will make it more resilient to changes in the operating system.

It was only there on first activation.

I think I remember something about wineskin and wondered if I'd started the wrong program.

I wouldn't worry about it.

The warning pops up all the time from all kinds of apps when you first install it. I've had this happen with Dropbox and Photoshop.

Branflakes it's the first time I've ever seen a message like that.
