I am not with Laminar Research; just a flight simmer.
X-Plane is resource hungry whereby good cooling is required.for the graphics card and the CPU. X-plane will successfully run on a laptop if it is a designated gaming machine.
Dedicated X-Plane users usually run a purpose built Windows based PC which allows for future upgrades rather than purchasing a new unit every few years. These units have additional cooling included when purchased. Any Mac system is basically a sealed unit and is difficult to upgrade.
You need to look at the specifications to successfully run X-Plane which can be found at http://www.x-plane.com/kb/x-plane-11-system-requirements/ and compare with your system. Many flight simmers build/purchase a system that is equal to or has higher specifications than the recommended systems.
