Homebrew (“Brew”) per se did not have issues after the Catalina upgrade. However, some packages delivered through formulae and casks have not been updated for Catalina and are stuck back in Mojave (or High Sierra, eek!). Old packages will likely have issues with Catalina since a lot has changed. For example, Catalina now uses Ruby 2.6. Homebrew (brew) is a free and open-source package manager that allows installing apps and software in macOS, depending on the user’s desire. It has been recommended for its simplicity and effectiveness in saving time and effort. Its famous description is “The missing package manager for macOS”. Steps to Install PostgreSQL Server on macOS Catalina. Install Homebrew. Open Terminal and then paste this command to install Homebrew. Homebrew is a clever application that will help us to install almost anything on macOS. Press Enter to start the installation.
Installing Drush on MacOSX with Composer
In order to install Drush, you should first install Composer. Composer is often required for Drupal 8 and once Composer is installed, installing Drush is easy.
1. Open the Terminal app on your Mac.
2. Install Homebrew via the instructions here: https://brew.sh/
3. Install Composer globally on your Mac with this command:
brew install composer
4. If your computer doesn’t have a “/usr/local/bin” directory, create that first with this command:
sudo mkdir -p /usr/local/bin
…that creates the directory; you should be prompted to enter your computer’s password.
Now, when you type composer --version and press Enter, we’ll see that you have Composer installed!
5. Install Drush via Composer:
Note!: Please do not install Drush using composer global require. See Pantheon’s article, Fixing the Composer Global command.
Instead, first install the Composer global require command:
composer global require consolidation/cgr
6. Add the vendor/bin from the Composer home directory to your $PATH.
(Thereafter, you may substitute cgr for any command line tool whose installation instructions recommends the use of Composer global require. Example: cgr drush/drush)
If you get a popup to install the Xcode Developer tools, go ahead and install Xcode.
7. Update the system $PATH:
vim ~/.bash_profile
to edit the file press the i key to enter Insert mode
…next, copy and paste this into that file:
export PATH='$HOME/.composer/vendor/bin:$PATH'PATH='$(composer config -g home)/vendor/bin:$PATH'
Press the Escape (esc) key to switch back to command mode.
Type :wq and press Enter to save and quit the file.
8. Quit the Terminal app (or, run the “source” command to load the .bash_profile file without having to restart the Terminal.)
To run the source command:
source ~/.bash_profile
9. Now you will actually install Drush:
How To Install Brew On Macos Catalina
Install latest stable Drush:
cgr drush/drush
Now if you type drush and press Enter, you’ll see that Drush is installed, and working on your machine!
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:
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.

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.
