doc: install qt5 when building on macOS
Brew has updated such that qt now refers to Qt 6.0.1. If builders
install this, configure will not work pick up qt. For now, install
qt@5 (5.15.2), until required build system and likely source changes
are made.

macOS Build Instructions and Notes

The commands in this guide should be executed in a Terminal application. The built-in one is located in

/Applications/Utilities/Terminal.app

Preparation

Install the macOS command line tools:

xcode-select --install

When the popup appears, click Install.

Then install Homebrew.

Dependencies

brew install automake libtool boost miniupnpc libnatpmp pkg-config python qt@5 libevent qrencode

If you run into issues, check Homebrew's troubleshooting page. See dependencies.md for a complete overview.

If you want to build the disk image with make deploy (.dmg / optional), you need RSVG:

brew install librsvg

and macdeployqtplus dependencies:

pip3 install ds_store mac_alias

The wallet support requires one or both of the dependencies (SQLite and Berkeley DB) in the sections below. To build Bitcoin Core without wallet, see Disable-wallet mode.

SQLite

Usually, macOS installation already has a suitable SQLite installation. Also, the Homebrew package could be installed:

brew install sqlite

In that case the Homebrew package will prevail.

Berkeley DB

It is recommended to use Berkeley DB 4.8. If you have to build it yourself, you can use this script to install it like so:

./contrib/install_db4.sh .

from the root of the repository.

Also, the Homebrew package could be installed:

brew install berkeley-db4

Build Bitcoin Core

  1. Clone the Bitcoin Core source code:

    git clone https://github.com/bitcoin/bitcoin
    cd bitcoin
    
  2. Build Bitcoin Core:

    Configure and build the headless Bitcoin Core binaries as well as the GUI (if Qt is found).

    You can disable the GUI build by passing --without-gui to configure.

    ./autogen.sh
    ./configure
    make
    
  3. It is recommended to build and run the unit tests:

    make check
    
  4. You can also create a .dmg that contains the .app bundle (optional):

    make deploy
    

Disable-wallet mode

When the intention is to run only a P2P node without a wallet, Bitcoin Core may be compiled in disable-wallet mode with:

./configure --disable-wallet

In this case there is no dependency on Berkeley DB and SQLite.

Mining is also possible in disable-wallet mode using the getblocktemplate RPC call.

Running

Bitcoin Core is now available at ./src/bitcoind

Before running, you may create an empty configuration file:

mkdir -p "/Users/${USER}/Library/Application Support/Bitcoin"

touch "/Users/${USER}/Library/Application Support/Bitcoin/bitcoin.conf"

chmod 600 "/Users/${USER}/Library/Application Support/Bitcoin/bitcoin.conf"

The first time you run bitcoind, it will start downloading the blockchain. This process could take many hours, or even days on slower than average systems.

You can monitor the download process by looking at the debug.log file:

tail -f $HOME/Library/Application\ Support/Bitcoin/debug.log

Other commands:

./src/bitcoind -daemon      # Starts the bitcoin daemon.
./src/bitcoin-cli --help    # Outputs a list of command-line options.
./src/bitcoin-cli help      # Outputs a list of RPC commands when the daemon is running.

Notes

  • Tested on OS X 10.14 Mojave through macOS 11 Big Sur on 64-bit Intel processors only.
  • Building with downloaded Qt binaries is not officially supported. See the notes in #7714.
