These instructions are strictly testnet only

Install Bitcoin Testnet

1. Download the latest Bitcoin core dmg file for the Mac from the Bitcoin.org site - https://bitcoin.org/en/download
2. Install Bitcore from the DMG file to the Applications folder on Mac
3. Create a bitcoin.conf file in the folder ~/Library/Application Support/Bitcoin with the following content:

testnet=1
txindex=1
server=1
dbcache=6000
daemon=1
rpcuser=<user>
rpcpassword=<password>
zmqpubrawblock=tcp://127.0.0.1:28332
zmqpubrawtx=tcp://127.0.0.1:28333

4. Run Bitcoin core application. It will connect with the testnet and download and sync with the testnet blockchain

Install LND

1. Download latest mac compatible (darwin-amd64) LND release from the release page:https://github.com/lightningnetwork/lnd/releases
2. E.g. for the version 0.12.1 the link to be dowloaded is: https://github.com/lightningnetwork/lnd/releases/download/v0.12.1-beta/lnd-darwin-amd64-v0.12.1-beta.tar.gz
3. Unzip the files and save in a folder locally. Two files will be extracted from the zip folder - lnd and lncli
4. Run lnd once and kill the process after it prompts to unlock/create the node
5. Go to the folder ~/Library/Application Support/Lnd and create a file lnd.conf in that location, with the below content:

[Application Options]
alias=<Your Alias>
color=#6AAABF
debuglevel=debug
restlisten=0.0.0.0:8080
externalip=<your ip address>:19735
listen=0.0.0.0:19735
accept-keysend=true
[Bitcoin]
#enable either testnet or mainnet
bitcoin.active=1
bitcoin.testnet=1
bitcoin.node=bitcoind
[Bitcoind]
bitcoind.rpcuser=<User specified in bitcoin.conf>
bitcoind.rpcpass=<Password specified in bitcoin.conf>
bitcoind.rpchost=127.0.0.1
bitcoind.zmqpubrawblock=tcp://127.0.0.1:28332
bitcoind.zmqpubrawtx=tcp://127.0.0.1:28333

6. Run lnd again in a terminal window, it will prompt to create/unlock the node
7. Open another terminal window and go the folder which has the lncli file.
8. Run lncli to create/unlock the node
9. Once unlocked, the node will run and sync with the testnet network. Watch the log/progress in the first terminal window
