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

Setup

This section 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 lima for VM and socket_vmnet for bridge.
brew install lima 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 Auto set route and DNS if you want to auto execute it.

# Get IP of dae VM.

# Set gateway of macOS host to dae VM.
sudo route delete default; sudo route add default $dae_ip
# Set DNS of macOS host to dae VM.
networksetup -setdnsservers Wi-Fi $dae_ip

Verify that we were successful.

# Verify.
curl -v ipinfo.io

Auto set route and DNS

Write a script to execute.
