Answer 1

The "72" in "php72-phalcon" refers to PHP 7.2, but you are using PHP 7.4, so it's not going to be compatible - extensions need to be built against the correct version of PHP in order to run. The version of Phalcon it's installing (3.4.2) is also out of date, because that was the last version supported on that version of PHP.

The instructions for installing Phalcon 4.0 on a Mac are here: https://docs.phalcon.io/4.0/en/installation#macos

They refer to a different homebrew repository:

brew tap phalcon/extension https://github.com/phalcon/homebrew-tap
brew install phalcon
