-Building for macOS

-To build Proton for macOS, install the latest Xcode command line tools, as

-use a packager like [Homebrew](https://brew.sh/) to find these packages.

-        brew install cmake nasm libtool automake

-Then run:

-        ./build_proton.sh

-It is important to examine the output near the end of

-relevant libraries required to build Wine properly.
