Apple Seeds Second Beta of macOS Mojave 10.14.5 Update to Developers

by

Apple today seeded the second beta of an upcoming macOS Mojave 10.14.5 update to developers for testing purposes, a week and a half after launching the first beta and two weeks 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.

There were no major changes discovered in the first macOS Mojave 10.14.5 beta, 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.

10.14.5 DP2 went back to BootROM 141.0.0.0.0 for MP5.1 Mac Pros, again.

10.14.5 DP1 having the 142.0.0.0.0 W3xxx Xeon "bricker" ('https://forums.macrumors.com/threads/mp5-1-bootrom-thread-10-14-5-dp2-went-back-to-141-0-0-0-0.2132317/') BootROM after pulling back to 141.0.0.0.0 with 10.14.4 final was the perfect example of one hand not knowing what the other was doing.

I like how the macOS seed announcements are now a sidebar notation on MacRumors.

Most of the point releases after the GM have been pretty lackluster this year. No major changes. Guess we’ll have to wait for 10.15. Looking forward to WWDC. Hope they’ll devote a decent amount of time to it and I hope the next version has a cool name like Mojave.

Maybe Sonoma? Or Death Valley?
