At first, I didn’t love that concept.
If you’re looking to try the old 2000-era game on your Mac,Blizzard has instructions here.
The game does not support even Intel’s better Iris GPUs.
I tried my luck on three Windows PCs.
Also great was a gaming laptop with an Intel Core i7-8750 and a Nvidia 2080 Max-Q GPU.
But a Dell XPS 13 with an Intel Core i7-1065G7 and Intel integrated Iris Plus graphics was a no-go.
The game would simply pop up an fault signal when I tried to launch it.
On the same Dell, I was able to download and play Diablo 3 on it perfectly fine.
Fortunately,you’re free to always play it on a console instead.
