I have a 2015-model Mac. For quite some time now, they've been Intel based. MacOS offers a utility called Boot Camp which allows all recent Macs to be booted directly into Windows. MacOS walks you through the set up process, and it's a piece of cake if you're reasonably competent with computer tech. Once running Windows, you'd never know you were running a Mac. All the hardware has Windows drivers, and it's fabulous. A native Windows OS not running in a virtual machine (like Parallels or VMWare). Just like dual-booting into Linux (if that's your bag). I personally put Windows on a second hard drive, but you have the option of partitioning your primary drive and put Windows on part of it.
I run AutoCAD and SolidWorks on it and it performs like any other Windows computer I've ever had. Highly recommend this option. And it doesn't take up additional valuable physical real estate because you're not in need of space for an extra computer, monitor, keyboard, mouse, etc. Obviously your flight simulator accessories have to be USB devices because Macs don't have serial ports like computers of old.
Best of luck!
