Apple today seeded the fourth beta of an upcoming macOS Mojave 10.14.3 update to developers and public beta testers, a few days after releasing the third beta and more than a month after the launch of macOS Mojave 10.14.2.

The new macOS Mojave 10.14.3 beta can be downloaded through the Software Update mechanism in System Preferences after the proper profile has been installed from Apple's Developer Center or the public beta testing site.

We don't yet know what improvements the next update to macOS Mojave will bring, but it is likely to include bug fixes and performance improvements for issues that weren't able to be addressed in the macOS 10.14.2 update.

No new features were found in the first three betas of macOS 10.14.3, but if we find anything new in the fourth beta, we'll update this post.

The new Macbook Air does include a T2 chip. https://www.apple.com/macbook-air/

My 2018 mini has the T2 chip as well, but I have had no issues with it using Mojave.

As for Mojave, it has been rock solid on both my personal minis as well as my work mac pro 2012 and macbook air 2014.

I have no doubt it will be 'rock solid' for almost everyone. The issue is, when the time comes you want to replace or upgrade the storage drive in any of the T2 chip equipped macs, you can pretty much forget about it and just get a new motherboard or replace the computer entirely.

I fix Macs as a hobby. And I can't tell you how many Macs I've got running again for several years just but swapping out the faulty storage drive (ssd or hdd).

That will no longer be possible with 'T' chip equipped Macs, which is disappointing to say the least.

I'd like to know if the Air also has the T2 and how are people finding it.
I have a brand-new Air with the TouchID, so I presume it has the T2. So far it's been working fine. Had one or two WiFi disconnects with it over the first few weeks but other than that it's been solid. Upgraded from an OG 12" MacBook, so for me the Air is a huge upgrade as well as far as speed.

10.14.2 has been so rock solid for me. I love how it can only get better. The iOS 12/Mojave cycle has been a real step forward for Apple software quality, in my opinion of course.

Is there a reason why they never state what's in the beta?
