However, the Mac gaming ecosystem is not as good as the Windows gaming ecosystem. Relying on its stable smooth system and great performance, lots of people are willing to use Mac books to work. Is there another way of playing Windows steam games on a Mac without Boot Camp?' And I know Boot Camp can help me to install Windows, but it will take a lot of space. I bought a new Mac book Pro 13, and I bought lots of games on steam that are not supported by Mac OS.
