Here’s how to install an SSL/TLS certificate on Mac OS X El Capitan

Mac OS X El Capitan (v.10.11) is the twelfth major version of Apple’s macOS. This operating system is widely used in Macintosh computers. This article will help you ease through SSL/TLS certificate installation on Mac OS X El Capitan (v.10.11) and beyond.

Before we dive into SSL/TLS certificate installation on Mac OS X El Capitan, you need to know a few things. First, you’ll need to have a CSR (certificate signing request). Without a CSR you won’t be able to purchase an SSL certificate, let alone install one. The first portion of this blog will focus on the CSR generation process on macOS. If you have already generated your CSR, you can skip down to the installation part by clicking here.

Generating CSR for Mac OS X El Capitan

We will tell you what other sites won’t: CSR generation is super-easy. Other websites will take you through an arduous process, but we won’t. For your comfort, we have developed an awesome, free-to-use CSR Generation tool. Generating a CSR in your browser is much easier than doing it on your server.

If you haven’t bought an SSL/TLS certificate, you just got lucky! That’s because no other SSL certificate provider provides certs at the prices that we offer. Check out our super-affordable range of products, make an order and paste the CSR you just generated right there. It’s that simple.

Now that you’ve just generated your CSR and have your SSL certificate on hand, let’s get to work on the installation procedure.

Note: We assume that you’re done with the CSR creation as well as the certificate purchase processes. If not, refer the first portion of this post.

Your certificate issuing authority would have sent you the certificate files via email. Don’t get confused when you see two certificate files; you’ll need both. One of these files is called an ‘intermediate certificate.’ And the other one would be your SSL certificate. First, you’ll need to install your intermediate certificate. Let’s get it done.
