# Building Cake Wallet for macOS

## Requirements and Setup

The following are the system requirements to build Cake Wallet for your macOS device.

```
macOS >= 14.0 
Xcode 15.3
Flutter 3.19.x
```

### 1. Installing Package Dependencies

Cake Wallet cannot be built without the following packages installed on your build system.

For installing dependency tools you can use brew [Install brew](https://brew.sh).

You may easily install them on your build system with the following command:

`$ brew install cmake xz automake autoconf libtool boost@1.76 zmq cocoapods`

`$ brew link boost@1.76`

### 2. Installing Xcode

You may download and install the latest version of [Xcode](https://developer.apple.com/xcode/) from macOS App Store. 

### 3. Installing Flutter

Need to install flutter with version `3.19.x`. For this please check section [Install Flutter](https://docs.flutter.dev/get-started/install/macos/desktop?tab=download).

### 4. Installing rustup

Install rustup from the [rustup.rs](https://rustup.rs/) website.

### 5. Verify Installations

Verify that Flutter and Xcode have been correctly installed on your system with the following command:

`$ flutter doctor`

The output of this command will appear like this, indicating successful installations. If there are problems with your installation, they **must** be corrected before proceeding.
```
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, 3.19.x, on macOS 14.x.x)
[✓] Xcode - develop for iOS and macOS (Xcode 15.3)
```

### 6. Acquiring the Cake Wallet source code

Download the source code.

`$ git clone https://github.com/cake-tech/cake_wallet.git --branch main`

Proceed into the source code before proceeding with the next steps:

`$ cd cake_wallet/scripts/macos/`

### 7. Execute Build & Setup Commands for Cake Wallet

We need to generate project settings like app name, app icon, package name, etc. For this need to setup environment variables and configure project files. 

Please pick what app you want to build: cakewallet or monero.com.

`$ source ./app_env.sh <cakewallet OR monero.com>`
(it should be like `$ source ./app_env.sh cakewallet` or `$ source ./app_env.sh monero.com`)

Then run configuration script for setup app name, app icon and etc:

`$ ./app_config.sh`

Build the Monero libraries and their dependencies:

`$ ./build_monero_all.sh`

If you be needed to build universal monero lib, then it will require additional steps. Steps for build universal monero lib on mac with Apple Silicon (arm64):

- Need to install Rosetta: `$ softwareupdate --install-rosetta`
- Need to install [Brew](https://brew.sh/) with rosetta: `$ arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"` (or take another way to install brew, but be use that you have installed it into /usr/local as it's using for x86_64 macs)
- Install dependencies for build monero wallet lib for x86_64 with brew: `$ arch -x86_64 /usr/local/bin/brew install automake autoconf libtool openssl boost@1.76 zmq` and link installed boost@1.76 for x86_64 `$ arch -x86_64 /usr/local/bin/brew link boost@1.76`
- Run building script with additional argument: `$ ./build_monero_all.sh universal`

If you will be needed to build monero wallet lib only for x86_64 on arm64 mac, then you need use steps above, but run build script with rosetta without arguments: `$ arch -x86_64 ./build_monero_all.sh`.

It is now time to change back to the base directory of the Cake Wallet source code:

`$ cd ../../`

Install Flutter package dependencies with this command:

`$ flutter pub get`

Your Cake Wallet binary will be built with cryptographic salts, which are used for secure encryption of your data. You may generate these secret salts with the following command:

`$ flutter packages pub run tool/generate_new_secrets.dart`

Then we need to generate localization files and mobx models.

`$ ./configure_cake_wallet.sh macos`

### 8. Build!

`$ flutter build macos --release`

Then you can open `macos/Runner.xcworkspace` with Xcode and you can to archive the application.

Or if you want to run to connected device:

`$ flutter run --release`
