I'm trying to install EE 3.2.1 on localhost on my Mac. But I'm getting the following 'undefined function' error. Through Google I can't find any mention of anyone else having the same issue. What might be the cause?
Call to undefined function EllisLab\ExpressionEngine\Service\License\openssl_verify() in /Users/xxxxx/www/iffa/system/ee/EllisLab/ExpressionEngine/Service/License/License.php on line 248
My system versions are: Apache: 5.5.31 mySQL: 5.6.25
