In this day and age, most laptops and devices come with a wireless adapter built-in, even the latest Raspberry Pi includes wireless. This is lucky for when you can’t get to the router in your house, or the cable just won’t reach your favourite seat, or when your ethernet connection is disabled by an update.
Some people found this out the hard way this morning when Apple published an update over the weekend which disabled the ethernet port in the El Capitan distribution of their operating system. The reason for the disabled port? An update for the System integrity protection system, a system designed to keep your computer secure by disabling malicious kernel extensions (kext) (the equivalent of drivers for Windows or Linux users). Sadly a small update blacklisted the ethernet ports kext.
While an update was quickly released to fix the issue, some people still had the issue of it disabling their system before they were able to update to the latest version. The idea is that it’s all done behind the scenes, without you having to select the update or even know about it, kexts are updated silently. These updates run even if you have disabled the standard automatic update.
Do you use cabled connections or are you constantly on the wi-fi? Could you live with the other? What would you do if someone accidentally disabled the wireless in your computer, laptop or even your phone?
