So with that being said, the first thing you need to do is check to see what version you have.

There are two ways to do this – 1) connect to a Wi-Fi network to circumvent the Ethernet port altogether so you can install the update that way, or 2) if you rely on Ethernet, and cannot connect to a Wi-Fi network, you’ll have to roll back your most recent update so you can download the latest security update instead. Apple says that if you have version 3.28.1 installed, you’ll need to install the updated version, which is 3.28.2, to fix the problem. The first thing you need to do is check to see what version of the “Incompatible Kernel Extension Configuration Data” you have installed on your Mac is. Since those of you with a disabled Ethernet port after installing the latest security update will probably want to get it up and running again, Apple has provided a fix for you. In this tutorial, we’ll go over the steps to fix the problem yourself. Apple has issued a support document on Sunday that notes how to fix the problem.

The security update, known as “031-51913 Incompatible Kernel Extension Configuration Data 3.28.1,” reportedly blacklists the Broadcom BCM5701 driver used by the Ethernet port that comes standard on many Mac machines.įortunately, there’s a light at the end of the tunnel for anyone experiencing issues with their Ethernet ports after installing this security update. Although a lot of modern Macs don’t even have an Ethernet port, many models still carry it and many people still love using a wired internet connection because it’s faster, more reliable, and more secure than a wireless network. As my colleague Christian reported on Saturday, some Mac models have been plagued by non-working Ethernet ports after installing a new security update outed by Apple.
