Apple Seeds Third Beta of macOS Mojave 10.14.5 Update to Developers

Apple today seeded the third beta of an upcoming macOS Mojave 10.14.5 update to developers for testing purposes, two weeks after launching the second beta and a month after the launch of macOS Mojave 10.14.4.

The new macOS Mojave 10.14.5 beta can be downloaded through the Software Update mechanism in System Preferences after the proper profile has been installed from Apple's Developer Center.

It's not yet clear if there are new features in macOS Mojave 10.14.5, but it likely includes bug fixes and performance improvements to address issues that weren't able to be fixed in the macOS Mojave 10.14.4 update.

This update will make macOS more secure because after macOS 10.14.5, new Mac apps released outside of the Mac App Store that want to have Apple's seal of approval will need to go through Apple's notarization security process.

There were no major changes to macOS discovered in the first two macOS Mojave 10.14.5 betas, but if we discover anything new in this beta, we'll update this post.

The prior update, macOS Mojave 10.14.4, brought the Apple News+ subscription service, expanded ‌Apple News‌ to Canada, and introduced a new automatic Safari Dark Mode feature for websites.
