Apple Reworks Security Update

Apple reissued a security update for OS X El Capitan systems after the initial update blocked the company’s own Ethernet drivers.

The first security update, installed on systems automatically, was a security measure designed to block kernel extensions harmful to the operating system.

Apple issued the update to blacklist problematic kernel extensions, but through a miscue on their own end, it also included the kernel extension information for its Ethernet drivers.

As soon as the update went out for OS X El Capitan systems, a process that did not require any user interaction, the Ethernet drivers ended up blocked and the affected Macs could no longer connect to the Internet via an Ethernet connection.

Apple quickly realized the issue and reissued the security update to resolve the blacklisting problem.

Apple said the Wi-Fi connection, which uses separate drivers, did not suffer from the issue. Also, Macs that connected to the Internet over Wi-Fi automatically updated to version 3.28.2. Should the Wi-Fi connection not work, however, users needed to manually install the reissued update to resolve the Ethernet connectivity bug.
