Hi @deryck,
To enable Imagick, you will need to install the Imagick extension from PECL.
If you’re on Windows, you’re in luck since you can simply select the DLL as a download option and then include that extension in the site’s php.ini.hbs file in conf/php.
On macOS and Linux, it requires compiling the extension using phpize. Also, if you’re on Catalina or newer, you will need to use the codesign tool on the resulting .so file otherwise it won’t be loaded.
With all of that said, we have immediate plans to re-add Imagick as an included extension since it’s something that WordPress looks for in its new Health Check.
