And keep in mind that PC will also be able to play high detail video games and run other demanding 3D/CAD software much better than a laptop. If you don't then buy or build a desktop PC for anywhere between $600 to $1000 and you should have a very capable Lumion machine. V-ray is also working for smooth and good quality of rendering for models of the different components which are related to a number of industries. If you absolutely need a portable device buy the Mac but don't expect to run Lumion much. Lumion is real-time rendering software which gives high quality of result in this process and deals with different industries.

The other downside to Apple's laptops in general is their poor cooling, they will heat up quickly and then slow down you performance to keep the temperatures below 90-100☌. I have a Macbook from 2015 with AMD graphics, it's a very capable machine but Lumion relies heavily on your graphics card so the Mac can't keep up. ' doesn't mean you'll get the same performance as a desktop).

I guess a beefy gaming laptop (aka not a MacBook) might get you somewhere but as with any laptop you'll end up paying more for less capable 'miniature' hardware (don't be fooled by 'mobile' versions of desktop graphics, just because it says 'gaming' or 'GTX. You will realize pretty quickly that you need a proper desktop graphics card to run Lumion with even just small projects. Try reading Lumions FAQ about graphics cards.
