🌐 Installing Chromium on Mac Apple M2 Pro (Tutorial)

Publish Date: Aug 16 '23

Let's just say I've never really had to use Chromium before, but my workplace requires us to use it for specific cases when testing.

I had the toughest time getting this thing to work on my Mac. Meanwhile, my remote colleagues had it working just fine.

I received a lot of these messages every time:

Chromium.app Not Supported Image

Chromium.app can't be verified

Meanwhile in my head I'm thinking, "this is easier if it was windows"! But this laptop I used is also a corporate laptop, which could also be a reason for these errors.

Well, if any of you need to use Chromium and have a Apple M2 Pro chip, then this tutorial should help you.

Install Homebrew

If you don't already have homebrew, please install it as we will be using this to download and install Chromium.

Step-By-Step Tutorial For Homebrew

If you already have homebrew, let's skip to the next section.

Install Chromium

After installing homebrew, keep your terminal open and run the following commands:

  1. brew install chromium --no-quarantine
  2. brew cu (upgrades chromium)

Easily done within baby steps (took me longer than it should have)!

Check your applications and try to open Chromium. If you are receiving this specific error message: "Chromium.app is damaged and can't be opened. You should move it to the Trash." Don't trash it, instead click "cancel" and check out the quick fix for this below.

Damaged App Fix

In your terminal, enter the following command:

xattr -cr /Applications/Chromium.app

Attempt to re-open Chromium, and the error message should now be gone!

If it is not gone, please comment the type of error message you receive. I can try to provide resources for you. Any feedback is accepted!

Please check out the resources I've gathered from below to make this into one tutorial. ❤️

    brew cu was not a valid command, but this did allow me to get Chromium installed and running on an M3 MacBook Air. Thanks!

      For future reference, this is because the extension is not installed to use "cu"

      brew tap buo/cask-upgrade

      Above command will enable the use of cu command to upgrade all packages.

    Thank you! This command "xattr -cr /Applications/Chromium.app" worked for me. But could you kindly tell me whether I'm adding or removing the CR extended attribute by using this command and also what that attribute does?
