Yesterday, Apple released a supplemental update of its macOS Mojave 10.14.5, which has been developed for 2018 and 2019 15-inch MacBook Pro models featuring a T2 security chip.
Users can download the new update via the “Software Update” section of System Preferences on all compatible Macs.
Apple’s release notes state that the updated version of macOS Mojave 10.14.5 addresses a “firmware issue” impacting Macs with a T2 chip.
At this point, the company has provided no additional information, so we don’t know what the specific firmware issue might be. Nevertheless, more information will be available as soon as the security notes are made public.
“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.

Additionally, Apple made minor changes to the Apple News+ interface, allowing users to follow a magazine directly from the catalog browsing view, and included some improvements to the audio latency on 2018 machines.
