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.

I will skip HS entirely, for me it's the worst version of macOS released yet. Huge battery drain, slow and unresponsive on my rMBP 2015 (had it till the previous beta). Since I reversed to Sierra, everythings perfectly fine again. :)

well I'm against the idea of realizing a new OS very year and I'm a fan of please fix stability and performance and stay with one OS for at least 2 to 3 years but this time I really hope they make a new OS and forget that Drunk Sierra sorry High Sierra ever existed.

I would say that High Sierra, Sierra and El Capitan are not "new OS" but rather minor updates (which is really disappointing). New Safari update with a tracking protection isn't really what my concept of a major update / new OS is.

When are they going to start fixing simple things like the Email app?

Marking things as spam does nothing! They seem to have some sort of shady deal with Facebook - you can mark their emails as spam a million times and they still get through!!!! Argh!!

That's just it, it used to be that way! When they were doing releases every two years, it was the time period when MacOS was most stable. Then starting with Mavericks they started releasing every year and quality has gone downhill since.
