In order to enable Push Notifications on your website for Safari browser on Mac computers, you will need a P12 certificate that is issued directly by Apple. Keep in mind that iOS does not support web push notifications at this time. This guide is therefore only applicable to Safari on Mac computers. Getting a P12 certificate is simple and we estimate it to be a ~30 minute effort which includes testing. Follow the following steps to get a P12 certificate:
Step 1: Create an Apple Developer Account
In order to get a P12 from Apple for your site, you first need to create an Apple Developer Account. We recommend you sign up as a sole proprietor/single person business as that would decrease your fee to just $99 per year. You will be paying this annual enrollment fee to Apple directly.
