setting up a react native development environment on a mac with apple silicon (m1 or m2 chips) requires a few specific steps due to the architecture differences. this guide will walk you through the entire process, from installing necessary tools to running your first react native application.

step 1: install homebrew

homebrew is a package manager for macos that simplifies the installation of software.

1. open your terminal.
2. run the following command to install homebrew:

```bash
/bin/bash -c "$(curl -fssl https://raw.githubusercontent.com/hom...)"
```

3. after installation, add homebrew to your shell profile (if it's not automatically added). you can do this by adding the following lines to your `~/.zprofile` or `~/.bash_profile`:

```bash
export path="/opt/homebrew/bin:$path"
```

4. restart your terminal or run `source ~/.zprofile` (or `source ~/.bash_profile`) to apply the changes.

step 2: install node.js

react native requires node.js. you can install it using homebrew.

```bash
brew install node
```

to verify the installation, run:

```bash
node -v
npm -v
```

step 3: install watchman

watchman is a tool developed by facebook for watching changes in the filesystem. it is recommended for react native development.

```bash
brew install watchman
```

step 4: install xcode

xcode is required for ios development.

1. open the app store.
2. search for "xcode" and install it.
3. once installed, open xcode and agree to the license agreement.
4. install the required components by going to *xcode preferences locations* and selecting the appropriate command-line tools.

step 5: install cocoapods

cocoapods is a dependency manager for swift and objective-c projects, which is also used for managing react native dependencies for ios projects.

```bash
sudo gem install cocoapods
```

step 6: install react native cli

react native can be set up using the react native cli. install it globally using npm:

```bash
