Just two days after releasing it to developers, Apple has seeded MacOS Mojave 10.14.1 to public beta testers. Those with registered Macs in the Apple Beta Program can now download the update via the Software Update feature in settings.
Apple, as they normally do, did not release any Release Notes with the update so what exactly is contained is not clear from a bug fixing perspective. What it does contain is Group FaceTime which also mimics the iOS 12.1 beta build from last week.
How long 10.14.1 will remain in beta is not clear either. The first beta to developers was released on Tuesday to developers and will likely go through another cycle or two before it is released. That said, WatchOS 5.0.1, which went into beta last week, was released today. That could mean that we will see it pretty quickly… or not. Generally speaking, these .1 releases do get out to the public pretty quickly.
You can sign up for the MacOS beta program here but keep in mind that the software is beta, meaning that it could contain bugs or issues that impact your daily use of your Mac. Unless you really need to test it, it is recommend to wait until it is released to the general public.
