But the best option for mac is to build it yourself. More info here.

apt install qemu-system-i386 qemu-utils

brew install i686-elf-gcc

./Scripts/i686-elf-tools.sh

brew install nasm

apt install nasm

Macabuilder is a build system developed to simplify Macaron OS building process. You can find build instructions here.

After everything's set up, just launch Macabuilder executable from the root project directory. It will find MacaronOS.maca file, build and run MacaronOS.
