Apple on Thursday seeded the fourth beta of iOS 12.1.3 to developers. The release comes just three days after the beta 3 rollout, and registered developers can install the update via the iOS over-the-air mechanism, or through Apple’s Dev Center.

We’re expecting 12.1.3 to be mostly bug fixes and under-the-hood improvements, and thus far the betas have proven that correct. Nevertheless, we’re installing today’s release and will be sure to report back if we discover anything worth noting.

Additionally, Apple has seeded beta 4 of macOS Mojave 10.14.3 to developers this morning. Again, we’re expecting mostly bug fixes and performance improvements out of 10.14.3, but we’ll be sure to update this post if we spot any significant changes.

As always, if you see something new in today’s betas that we haven’t mentioned yet, be sure to let us know about it in the comment section below!
