Supplemental updates may not be everyone’s favorite thing, but they come in handy.
As such, Apple has issued a supplemental update for macOS Mojave 10.14.5 for users of the 15-inch MacBook Pro, a recommended download that fixes a problem associated with the built-in T2 Security Chip.
The macOS Mojave 10.14.5 Supplemental Update for MacBook Pro is noted as addressing a “firmware issue that specifically affects versions of the 15-inch MacBook Pro equipped with the T2 Security Chip. This effectively covers all MacBook Pro models introduced since 2018.
The update weighs in at a 952.9 megabyte download, and can be downloaded from the support page rather than as a standard system update at this time. Specific changes to the security features have yet to be updated.
It is unclear what exact issue the update fixes, but the T2 chip has been blamed for a number of problems since its introduction. The T2 chip has been found to block some third-party Mac repairs from being performed, may have caused errors for some MacBook Pro users installing macOS Mojave, kernel panics, and is also reportedly interfering with some professional audio interfaces.
The T2 processor handles a number of functions for the macOS, including boot and security functions, faster disk encryption to onboard flash storage, regulating fan speeds, managing speaker functions, securing the built-in microphones, managing the image quality of the FaceTime camera, and powers the “Hey Siri” vocal prompts for Apple’s digital assistant.
If you’ve had a chance to try the update and have any feedback to offer, please let us know what you make of it in the comments.
