Things are done differently on Apple, especially with the latest MacOS, Catalina. When I was navigating these steps, I found them scattered across the internet. This guide aims to provide a centralized tutorial for getting the Expo Client up and running on MacOS Catalina.
1. Download a Code Editor
First, you'll want to download your preferred code editor. I personally recommend Visual Studio Code, which is:
- Free to use
- Intuitive
- Offers a wide range of add-ons to enhance development
Download Visual Studio Code here.
2. Install Node.js
There are primarily two ways to install Node.js on MacOS:
- Download Node.js from its official website.
- Install it using Homebrew from the command line. Here's a helpful article on how to do that.
Note: Due to the security settings of Catalina, you might encounter issues when trying to install applications globally. If you downloaded Node.js from its website, follow these steps to avoid such issues:
-
Create an
npm-globaldirectory if it doesn't exist:mkdir ~/npm-global -
Set the npm directory to the one you just created:
npm config set prefix '~/npm-global' -
Create a
.zshrcfile and open it:touch .zshrc open -e .zshrc -
Add the following to the
.zshrcfile:npm config set prefix '~/npm-global' export PATH=~/npm-global/bin:$PATH -
Close the file and restart your terminal.

3. Install the Expo Client
Catalina's security settings can be a challenge for global installations. Instead of the standard installation process, use the following command:
sudo npm i -g --unsafe-perm expo-cli
Important: Using sudo will prompt you for a password. The --unsafe-perm flag bypasses Catalina's security settings, allowing you to install the Expo Client globally.
And voila! You've successfully installed the Expo client on your Mac.
