Brew install openconnect (M1 MacBook Air). GitHub Gist: instantly share code, notes, and snippets. Brew untap of an official tap you don’t use (e.g. Homebrew/homebrew-cask) will ensure it’s no longer automatically retapped; brew casks is a new command implemented in Bash to speedily output all casks available to install (like brew formulae) brew info -cask -json=v2 includes whether a cask is outdated and the currently installed versions. I recently purchased a MacBook Pro 13' with the M1 chip and transferred all my data over using a Time Machine backup. Homebrew packages are currently installed in /usr/local/opt/ but it is my understanding that they should be under /opt/homebrew for Apple Silicon Macs. Homebrew lets you use commands to download and install Python, Ruby, MongoDB, PHP, Git, Node.js, cask, colordiff, Nmap, and other Unix command-line utilities. In this guide, I’ll show you how to install Homebrew in macOS Catalina or M1 Mac. Requirements to install Homebrew on Mac How to install Homebrew on macOS Catalina or M1 Mac.

Friday, I received a snazzy new M1 Macbook Pro in the mail. This article outlines how I was able to set it up for doing web development. We'll set up Homebrew, PHP, MySQL, Composer, and Laravel Valet. Let's jump in!

The previous article outlines first impressions from the perspective of someone upgrading from a 2013 mac.

Setting up an M1 mac for PHP development is not much different than other macs. Unless you're using Docker, which doesn't work on the new ARM processor (yet — they're working on it). I expected to have way more problems being an early adopter, but Apple has done a wonderful job with their Rosetta 2 translation layer. It mostly feels invisible, so (except for a few terminal commands like homebrew) you hardly even notice it is there.

Mac M1 Install Homebrew

Homebrew

First, we'll need to install Homebrew. They don't have an ARM-compatible build ready yet, so this is where we'll need to use some Rosetta flags on the command line.

Install Rosetta on the command line with the following:

/usr/sbin/softwareupdate --install-rosetta --agree-to-license

Next, add this function to your .zshrc file. It makes a nice arm alias for running commands with x86_64 architecture flags. Perhaps calling it x86 would be better? Shoutout to Matt Stauffer for posting this.

You'll need to run the homebrew commands with this prefix for now. We can copy the script from their site, add our arm prefix, and homebrew should install!

PHP, MySQL, and Composer

Now that homebrew is installed, the rest of the Valet install is pretty much stock (except for Redis, which we'll get to in the next section).

PHP

Just run arm brew install php — it's that easy! You may want to restart your terminal after this.

MySQL

Normal besides the arm prefix again.

Composer

Run the download script from Composer's website, then move the PHAR file to the bin folder. Also we'll add the global composer vendor folder to our system path.

Now add the following line to your .zshrc file

Valet and Redis

Installing Valet should work as normal now. Run the following commands:

Brew M1 Mac

After that, I also ran cd ~/Code && valet park .

Installing Redis

Redis presented the only real speed bump I've encountered thus far. It installs via brew, but starting the Redis server doesn't work correctly (even though brew says it does). Until then, we can start the server manually.

First, run arm brew install redis to install it.

Next, install the Redis PHP extension with PECL — pecl install redis.

Starting the Server

Normally you'd use arm brew services start to start Redis (and at login), but it's not working yet. That command just runs redis-server under the hood. For some reason, this command only works with sudo right now. The workaround is to run this to start Redis server as a daemon:

Cleaning up after PECL (optional)
By default, PECL plops a new extension='redis.so' line at the top of the main php.ini file. I prefer to move this line to its own extension file. These steps are optional, but it's more in line with how extensions should be loaded in modern php versions.

Homebrew Big Sur

Remove the extension='redis.so' line that PECL added at the top of /usr/local/etc/php/7.4/php.ini.

Install Brew M1

Then create a file at /usr/local/etc/php/7.4/conf.d/ext-redis.ini with these contents:

After doing all of this, I'd recommend running valet restart. Enjoy developing Laravel apps on your new mac!
