If you’re keen on trying out macOS 10.14.3 Mojave before the public release, you can get on the Beta Software Program and opt to receive the update, the first public beta of which was released earlier today. While we know that a few bugs were fixed and some stability improvements made, we don’t expect any life-changing features. Apple did not publish release notes for this iteration.
To install the macOS 10.14.3 public beta update, you will need to be a part of the Apple Beta Software Program, after which you will be eligible to receive and install the update. However, do not install any beta software on your primary Mac. If you have a non-essential machine handy, you can try it on that one. Also, if you do plan on installing it, make sure you’ve got everything backed up to iCloud or an external drive. Betas have bugs, so you’re doing this at your own risk.
That having been said, it’s a good way to get in on the whole development cycle of macOS. Feedback is usually taken very seriously, and any reported bugs are looked into by Apple’s crack development team. If you’re a developer and have registered as one with Apple, you will also be eligible to receive developer beta versions of macOS, iOS, tvOS and watchOS.
Don’t expect major changes to iOS or tvOS, either. We know that iOS 12.1.1 brought several new features like dual SIM support for this year’s iPhone X variants, and also haptic touch for iPhone XR notification previews, but iOS 12.1.2 is more about stability improvements and more bug fixes. Feature additions to tvOS have been minimal as usual, and we don’t expect anything new here, either.
Nevertheless, major public beta versions are always exciting to try out, and it’s good to know that Apple takes developer and public tester feedback very seriously. Well, most of the time, at least.
