Apple releases macOS Mojave 10.14.5 Supplemental Update for MacBook Pro

Apple updates the 15-inch MacBook Pro for 2019

Apple released macOS Mojave 10.14.5 to the public earlier this month. Now, a little over a week later, the company has released a supplemental update for one specific version of the MacBook Pro lineup.

On Wednesday, Apple officially released a new update for macOS 10.14.5. This is a supplemental update to the desktop operating system, and it’s meant primarily for the 15-inch MacBook Pro models equipped with a T2 Security Chip. Apple says this update is meant to address a “firmware issue” with the model, but the announcement itself doesn’t go into any specifics.

The MacBook Pro Supplemental Update addresses a firmware issue affecting 15-inch MacBook Pro computers with T2 Security Chip, and is recommended for all users.

Apple is also directing folks interested in the details to a specific landing page for security updates to its platforms. At the time of publication, the latest security update Apple has listed is for watchOS 5.2.1, which was released on May 13 of this year. The company will likely update this page soon to reflect the release of macOS Mojave 10.14.5’s Supplemental Update for MacBook Pro.

This is an update that leans into security, especially as it relates to the T2 Security Chip, so if you do have this particular Mac notebook, it might be a good idea to update at your earliest convenience. Just make sure to block out plenty of time to get the software downloaded and installed on your machine.

The update measures in at 952.9MB.

The software is available beginning now. It comes on the heels of Apple launching updated 13- and 15-inch MacBook Pro models earlier this week. That includes the company’s first 8-core MacBook Pro, which Apple says is the fastest MacBook Pro to date. It is also equipped with the T2 Security Chip, so if you pick up your new MacBook Pro this week make sure to update your software.
