macOS 
The macOS quickstart is to paste the below into a terminal and execute it.
zsh
/bin/bash -c "$(curl -fsSL https://get.lando.dev/setup-lando.sh)"If you are looking to customize your install then advanced usage is for you.
Advanced 
The installation script has various options but you will need to download the script and invoke it directly.
zsh
# save the script
curl -fsSL https://get.lando.dev/setup-lando.sh -o setup-lando.sh
# make it executable
chmod +x ./setup-lando.sh
# get usage info
bash setup-lando.sh --helpUsage 
zsh
Usage: [NONINTERACTIVE=1] [CI=1] setup-lando.sh [options]
Options:
  --arch           installs for this arch [default: arm64]
  --dest           installs in this directory [default: ~/.lando/bin]
  --fat            installs fat cli <3.24 only, not recommended
  --no-setup       installs without running lando setup <3.24 only
  --os             installs for this os [default: macos]
  --syslink        installs symlink in /usr/local/bin [default: auto]
  --version        installs this version [default: stable]
  --debug          shows debug messages
  -h, --help       displays this message
  -y, --yes        runs with all defaults and no prompts, sets NONINTERACTIVE=1
Environment Variables:
  NONINTERACTIVE   installs without prompting for user input
  CI               installs in CI mode (e.g. does not prompt for user input)Some notes on advanced usage:
- If you are running in CIthen--syslinkwill be assumed
- If you have an existing installation of landoin/usr/local/binand can write to that location then--syslinkwill be assumed
- If you run in a non-tty environment eg GitHub Actions then --yeswill be assumed
- If you use --yesit is equivalent to settingNONINTERACTIVE=1
Environment Variables 
If you do not wish to download the script you can set options with environment variables and curl the script.
zsh
LANDO_VERSION=stable
LANDO_INSTALLER_ARCH=auto
LANDO_INSTALLER_DEBUG=0
LANDO_INSTALLER_DEST="~/.lando/bin"
LANDO_INSTALLER_FAT=0
LANDO_INSTALLER_OS=macos
LANDO_INSTALLER_SETUP=auto
LANDO_INSTALLER_SYSLINK=autoExamples 
These are equivalent commands and meant to demostrate environment variable usage vs direct invocation.
zsh
# use envvars
LANDO_VERSION=3.23.11 \
LANDO_INSTALLER_DEBUG=1 \
LANDO_INSTALLER_SYSLINK=1 \
  /bin/bash -c "$(curl -fsSL https://get.lando.dev/setup-lando.sh)"
# invoke directly
bash setup-lando.sh --version "3.23.11" --debug --syslink
