$ brew install qemu nasm gdb i386-elf-gcc i386-elf-grub bochs e2fsprogs xorriso
$ cd src && ./create_image.sh && ./build.sh qemu iso
✍🏻 If you get this error hdiutil: attach failed - no mountable file systems, installing might help extFS for MAC
Debuging
in build.sh, adding -s -S right after qemu to switch to debug mode. Currently, I use vscode + native debuge -> click Run -> choose "Attach to QEMU"
Monitoring
tail -f serial.log | while read line ; do echo $line ; done
✍🏻 Using tail in pipe way to color the output (like above) causes a delay -> have to manually saving in ide to get latest changes
