Magento installation stucks on mac

I tried to install the latest magento 2.3.4 on my mac osx catalina with mamp pro and php7.3.

 

It stucks on the web with 41% in the installation process and on CLI with “bin/magento setup:install” the process breaks with “missing following extensions: ‘intl’ ‘zip'”.

 

phpinfo shows that intl and zip module is enabled.
