2 Certificate install - Apple Mac

Apple Logo These instructions are for Apple Macs. There are separate certificate installation instructions for Apple iPhones & Ipads, Android 9&10, Android 11, Chromebooks and Windows devices.

On your Apple Mac, you may get certificate error messages when going to secure websites, or the sites might not load at all. Secure websites have addresses that begin with "https" and they show a padlock icon in Safari's address bar once they've loaded. To load these sites without the error messages you need to install N4L's security certificate onto your device.
 

1. Ensure you are connected to Kerikeri High School's 'KKHS_Mahi' wifi. Instructions on how to do this are available here.
