add_filter( 'genesis_footer_output', 'custom_genesis_do_footer_unmodified' );

  1. Help → Edit Custom Properties…
  2. Add this line to the file, save, and restart: ide.mac.transparentTitleBarAppearance=true

It should then take on the base colour of your theme.

Install MariaDB with brew on macOS and fix the “access denied” issue

Attempting mysql -u root fails with Access denied for user 'root'@'localhost immediately after doing brew install mariadb and starting mariadb with brew services start mariadb.

To fix it (with MariaDB still running):

  1. sudo mysql then enter your Mac user password
  2. ALTER USER 'root'@'localhost' IDENTIFIED BY 'newrootpassword'; replacing newrootpassword with the password you wish to use for the MariaDB root user.
  3. Ctrl-C to exit mysql.

You should then be able to connect to MariaDB with mysql -u root -p, then entering the root password when prompted.
