Make sure to check out Part One, How To Install Apache on macOS 10.15 Catalina Using Homebrew, which is a pre-requisite for this piece. In the past, I used to rely on the version of Apache and PHP that came pre-loaded with the OS on my MacBook Pro. I would then install the PHP extensions I needed (Xdebug, Redis, etc.) from Homebrew. How to install Homebrew on Mac What you need. Before you install Homebrew on Mac, you’ll need to make sure you have the following: A 64-bit Intel CPU or an Apple Silicon CPU (i.e., an M1 Mac) You can check if you have a compatible Mac by pressing cmd + spacebar, typing “About This Mac”, pressing return, and then checking the Processor. Open the Terminal app on your Mac. Install Homebrew via the instructions here: 3. Install Composer globally on your Mac with this command: brew install composer. If your computer doesn’t have a “/usr/local/bin” directory, create that first with this command: sudo mkdir -p /usr/local/bin. #Homebrew #macOS #AskDoudouInstalling and uninstalling Homebrew is straightforward as long as you understand the Mac Terminal. In this Tutorial, I will show.

PowerShell 7.0 or higher require macOS 10.13 and higher. All packages are available on our GitHubreleases page. After the package is installed, run pwsh from a terminal.

Note

PowerShell 7.1 is an in-place upgrade that removes PowerShell Core 6.x and 7.0.

The /usr/local/microsoft/powershell/6 folder is replaced by /usr/local/microsoft/powershell/7.

If you need to run an older version of PowerShell core side-by-side with PowerShell 7.1, installthe version you want using the binary archive method.

There are several ways to install PowerShell on macOS. Choose one of the following methods:

• Install using Homebrew. Homebrew is the preferred package manager for macOS.
• Install PowerShell via Direct Download
• Install from binary archives.

After installing PowerShell, you should install OpenSSL. OpenSSL isneeded for PowerShell remoting and CIM operations.

Installation of latest stable release via Homebrew on macOS 10.13 or higher

If the brew command is not found, you need to install Homebrew followingtheir instructions.

Now, you can install PowerShell:

Finally, verify that your install is working properly:

When new versions of PowerShell are released, update Homebrew's formulae and upgrade PowerShell:

Note

The commands above can be called from within a PowerShell (pwsh) host,but then the PowerShell shell must be exited and restarted to complete the upgradeand refresh the values shown in $PSVersionTable.

Installation of latest preview release via Homebrew on macOS 10.13 or higher

After you've installed Homebrew, you can install PowerShell. First, install the Cask-Versionspackage that lets you install alternative versions of cask packages:

Now, you can install PowerShell:

Finally, verify that your install is working properly:

When new versions of PowerShell are released, update Homebrew's formulae and upgrade PowerShell:

Note

The commands above can be called from within a PowerShell (pwsh) host,but then the PowerShell shell must be exited and restarted to complete the upgrade.and refresh the values shown in $PSVersionTable.

Installing PowerShell using the Homebrew tap method is also supported for stable and LTS versions.

You can now verify your install

When new versions of PowerShell are released, simply run the following command.

Note

Whether you use the cask or the tap method, when updating to a newer version of PowerShell, usethe same method you used to initially install PowerShell. If you use a different method, opening anew pwsh session will continue to use the older version of PowerShell.

If you do decide to use different methods, there are ways to correct the issue using theHomebrew link method.

Installation via Direct Download

Download the PKG package powershell-7.1.3-osx-x64.pkg from the releases page onto yourmacOS machine.

You can double-click the file and follow the prompts, or install it from the terminal:

Install OpenSSL. OpenSSL is needed for PowerShell remoting and CIMoperations.

Install as a .NET Global tool

If you already have the .NET Core SDK installed, it's easy to install PowerShellas a .NET Global tool.

Install Homebrew On Mac Catalina Free

The dotnet tool installer adds ~/.dotnet/tools to your PATH environment variable. However, thecurrently running shell does not have the updated PATH. You should be able to start PowerShellfrom a new shell by typing pwsh.

Install OpenSSL. OpenSSL is needed for PowerShell remoting and CIMoperations.

Binary Archives

PowerShell binary tar.gz archives are provided for the macOS platform to enable advanceddeployment scenarios. When you install using this method you must also manually install anydependencies.

Install OpenSSL. OpenSSL is needed for PowerShell remoting and CIMoperations.

Note

You can use this method to install any version of PowerShell including the latest:

• Stable release: https://aka.ms/powershell-release?tag=stable
• Preview release: https://aka.ms/powershell-release?tag=preview
• LTS release: https://aka.ms/powershell-release?tag=lts

Installing binary archives on macOS

Installing dependencies

OpenSSL is required for PowerShell remoting and CIM operations. You can install OpenSSL via MacPortsif needed.

Note

MacPorts and Homebrew can have problems when used to together on the same system. However,Homebrew does not have a package for OpenSSL 1.0. For more information, see theMacPorts FAQ.

1. Install the Xcode command-line tools. The Xcode tools are required by MacPorts.

2. Install MacPorts. If you need instructions, refer to theinstallation guide.

3. Update MacPorts by running sudo port selfupdate.

4. Upgrade MacPorts packages by running sudo port upgrade outdated.

5. Install OpenSSL by running sudo port install openssl10.

6. Link the libraries to make them available to PowerShell:

Uninstalling PowerShell

If you installed PowerShell with Homebrew, use the following command to uninstall:

If you installed PowerShell via direct download, PowerShell must be removed manually:

To remove the additional PowerShell paths, refer to the paths section in this documentand remove the paths using sudo rm.

Note

This is not necessary if you installed with Homebrew.

Paths

• $PSHOME is /usr/local/microsoft/powershell/7.1.3/
• User profiles will be read from ~/.config/powershell/profile.ps1
• Default profiles will be read from $PSHOME/profile.ps1
• User modules will be read from ~/.local/share/powershell/Modules
• Shared modules will be read from /usr/local/share/powershell/Modules
• Default modules will be read from $PSHOME/Modules
• PSReadline history will be recorded to ~/.local/share/powershell/PSReadLine/ConsoleHost_history.txt

The profiles respect PowerShell's per-host configuration. So the default host-specific profileexists at Microsoft.PowerShell_profile.ps1 in the same locations.

PowerShell respects the XDG Base Directory Specification on macOS.

Because macOS is a derivation of BSD, the prefix /usr/local is used instead of /opt. So,$PSHOME is /usr/local/microsoft/powershell/7.1.3/, and the symbolic link is placed at/usr/local/bin/pwsh.

Installation support

Microsoft supports the installation methods in this document. There may be other methods ofinstallation available from other sources. While those tools and methods may work, Microsoft cannotsupport those methods.

Setting Up A Database

We're going to install sqlite3 from homebrew because we can't use the built-in version with macOS Sierra without running into some troubles.

Rails ships with sqlite3 as the default database. Chances are you won't want to use it because it's stored as a simple file on disk. You'll probably want something more robust like MySQL or PostgreSQL.

There is a lot of documentation on both, so you can just pick one that seems like you'll be more comfortable with.

If you're new to Ruby on Rails or databases in general, I strongly recommend setting up PostgreSQL.

If you're coming from PHP, you may already be familiar with MySQL.

MySQL

You can install MySQL server and client from Homebrew:

Install Homebrew On Mac Catalina Os

Once this command is finished, it gives you a couple commands to run. Follow the instructions and run them:

By default the mysql user is root with no password.

When you're finished, you can skip to the Final Steps.

PostgreSQL

You can install PostgreSQL server and client from Homebrew:

Once this command is finished, it gives you a couple commands to run. Follow the instructions and run them:

By default the postgresql user is your current OS X username with no password. For example, my OS X user is named chris so I can login to postgresql with that username.
