For installing React Native CLI, you need a JDK, and either the Xcode or Android Studio. Install the Node and run the commands in a Terminal –

brew install node

brew install watchman

React Native has built-in command-line interfaces. Instead of installing & managing the specific version of CLI globally, it is recommended to access the current version at runtime with npx that ships with Node.js.

Install Xcode for Mac OS and Android Studio

Use the Mac App Store to install the Xcode and it will ensure the running of the IOS Simulator. Make sure that the current version of the installed Xcode is 9.4 or newer. First, install ‘Command Line Tools’ for Xcode and then choose ‘Preferences’ from the menu. Now move to the ‘Locations’ panel and install the relevant tools.
