Run on macOS

Install brew

For x86

You can install brew referring to official docs https://docs.brew.sh/Installation:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

For arm64

To install arm64 architecture packages, homebrew should be installed in /opt/homebrew:

cd /opt
sudo mkdir homebrew
sudo chown $(whoami):admin homebrew
curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew

Lima

This chapter intruduces how to use lima virtual machine to run dae, and proxy whole macOS host network.

First, we should install lima and socket_vmnet.

# Install socket_vmnet for bridge.
brew install socket_vmnet

# Set up the sudoers file for launching socket_vmnet from Lima
limactl sudoers >etc_sudoers.d_lima
sudo install -o root etc_sudoers.d_lima /etc/sudoers.d/lima

Then, configure lima configuration and dae VM configuration.

# Configure lima networks.
socket_vmnet_bin=$(readlink -f ${HOMEBREW_PREFIX}/opt/socket_vmnet)/bin/socket_vmnet
sed -ir "s#^ *socketVMNet:.*#  socketVMNet: \"${socket_vmnet_bin}\"#" .lima/_config/networks.yaml

# Configure dae vm.
mkdir ~/.lima/dae/
cat << 'EOF' | tee ~/.lima/dae/lima.yaml

Set default route of macOS to dae VM.

Note

You may need to execute this command every time you connect to network.

Refer to run a script after a interface comes up if you want to auto execute it.
