Cant install it

[gurtner-it]

Environment (please complete the following information):

• PHP IMAP version: [e.g. 3.0.11]
• PHP Version: MAMP is 8.0.8. On Mac is: 8.0.25
• Type of execution: MAMP
• Newest Mac OS

Cant install it on my mac:

Your requirements could not be resolved to an installable set of packages.

Problem 1
    - Root composer.json requires php-imap/php-imap ^5.0 -> satisfiable by php-imap/php-imap[5.0.0].
    - php-imap/php-imap 5.0.0 requires ext-imap * -> it is missing from your system. Install or enable PHP's imap extension.
  Problem 2
    - phpunit/phpunit[7.0.0, ..., 7.5.20] require php ^7.1 -> your php version (8.0.25) does not satisfy that requirement.
    - Root composer.json requires phpunit/phpunit ^7 -> satisfiable by phpunit/phpunit[7.0.0, ..., 7.5.20].

To enable extensions, verify that they are enabled in your .ini files:
    - /usr/local/etc/php/8.0/php.ini
    - /usr/local/etc/php/8.0/conf.d/ext-opcache.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, reverting ./composer.json to its original content.

Tried different things. I'm quite lost...

Thanks for the help. Sorry cant deliver more infos, baby is crying ;)
