Apple Seeds Fifth Beta of macOS High Sierra 10.13.3 to Developers [Update: Public Beta Available]

Apple today seeded the fifth beta of an upcoming macOS High Sierra 10.13.3 update to developers, one week after seeding the fourth beta and more than a month after releasing macOS High Sierra 10.13.2, the second major update to the macOS High Sierra operating system.

The new macOS High Sierra 10.13.3 beta can be downloaded from the Apple Developer Center or through the Software Update mechanism in the Mac App Store with the proper profile installed.

It's not yet clear what improvements the macOS High Sierra 10.13.3 update will bring, but it's likely to include bug fixes and performance improvements for issues that weren't addressed in macOS High Sierra 10.13.2. It offers additional fixes for the Spectre and Meltdown vulnerabilities that were discovered and publicized in early January and fixed initially in macOS High Sierra 10.13.2.

The update also fixes a bug that allows the App Store menu in the System Preferences to be unlocked with any password.

The previous macOS High Sierra 10.13.2 update focused solely on security fixes and performance improvements, with no new features introduced, and a supplemental update introduced a fix for the Spectre vulnerability.

Update: A new public beta of macOS High Sierra 10.13.3 is available for public beta testers.

I sure hope so! As a matter of fact, I am really hoping Apple does not release 10.14. this summer and just focuses on fixing the loooong list of bugs in this operating system.
Same with iOS. We need a snow leopard year for software. Only for them to just screw it all up again with tons of bugs in the next cycle but it would be nice to delay the pain. Haha.
Yeah, they really need to increase the new OS cycle to 2-3 years and not every year. It seems like by the time they get all the wrinkles ironed out, they release a new bug-filled OS that we have to wait another year to not be so buggy again. It's annoying.

The whole purpose off High Sierra was to fine tune Sierra. It is/was supposed to be a "snow leopard" type release... but has fallen short of that dream.
