### macOs on Mi1
Native build on M1 Mac has proved difficult at this stage for a number of reasons. I filed (and closed) a separate issue.
We can, however, get an x86 version of the toolchain working on M1 with these steps.
1. Ensure rosetta is installed. `/usr/sbin/softwareupdate --install-rosetta --agree-to-license`
2. Ensure Xcode command line tools are installed `xcode-select --install`
3. Install convince Homebrew to install an x86_64 version instead `arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"`. Ensure `/usr/local/bin` is early in your path.
4. Use the x86 homebrew to install the required packages `arch -x86_64 brew install bash wget make lhasa gmp mpfr libmpc flex gettext texinfo gcc make autoconf`
5. `git clone git@github.com:bebbo/amiga-gcc ; cd amiga-gcc`
6. specify x86 when building `CC=gcc-10 CXX=g++-10 SHELL=/usr/local/bin/bash arch -x86_64 gmake clean update all`.
7. profit!
