Apple has seeded the second public beta of macOS Mojave 10.14.5 today. The update is available for those with registered Macs in the Apple Public Beta program. If you have a registered device, you should have the update ready and waiting for you in Settings>Software Update on your Mac.
This second beta of Mojave 10.14.5 comes two weeks after the first public beta. Like the first beta, there are no new features in this build of macOS Mojave. Instead, this release is primarily focused on bug fixes, security improvements, and overall performance updates. That doesn’t necessarily mean there will not be new features by the time this version is released to the public. It just means, for now, that’s not the focus for the folks in Cupertino.
One of the biggest potential new features is the upcoming Apple TV app for macOS. During the “It’s show time” event, Apple highlighted that a dedicated TV app would be coming to macOS Mojave. With the company saying the new UI on Apple TV devices and on iOS would be in May, it is certainly possible that we will see a beta of it in macOS in an upcoming beta build. The new-look Apple TV app is already in the beta for iOS 12.3.
As always, both AverageAppleGuy.com and Apple do not recommend installing beta versions of Operating Systems on your primary or daily use devices in case you happen across a crippling bug.
