It's not yet clear what improvements the third update to macOS High Sierra 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.

The previous macOS High Sierra 10.13.2 update focused solely on security fixes and performance improvements, with no outward-facing changes introduced.

Update: Apple has also seeded the macOS High Sierra 10.13.3 update to public beta testers.

* 10.0: Important to finally ship. Dog-slow and unusable for a lot.
* 10.1: Important to ship same year. The usable 10.0.
* 10.2: Quartz Extreme and other improvements made it more usable. The release a lot of users made the jump to.
* 10.3: Safari, early FileVault (only worked for home directory), the brushed metal virus, and esoteric things like Pixlet. Might have broken certain Carbon apps with weird-colored text.
* 10.4: Spotlight, Core Data, and Dashboard widgets. Remember, the 2 years between 10.5 also brought a significant update that worked on Intel Macs.
* 10.5: Time Machine, Core Animation, bunch of UI fads, 64-bit UI. Dev cycle was slowed by iOS development.
* 10.6: The “good” release people remember. They took 2-years (thanks iOS) and fixed issues. This is what people want.
* 10.7: Particularly buggy with auto-save and thin scrollbars, but proper full-disk FileVault.
* 10.8: A less buggy 10.7 with its own issues.
* 10.9: Compressed memory, removal of some skeuomorphic crap, more in-line with iOS, but had its own issues.
* 10.10: More skeuomorphic purge, had its own issues.
* 10.11: New system font, Metal,better Mail/Notes. Felt so minor.
* 10.12: Siri, Safari Apple Pay, iCloud drive, and the most annoying “optimized storage”.
* 10.13: AFPS, Metal 2, Safari blocks annoying website features and tracking, but maybe the buggiest release ever.


It’s not the frequency of updates; it’s the lack of quality and persuit of short-term UI fads or dumb consumery apps, treating users as testers, and syncing releases to iOS.

did they fix the pause/play buttons playing/pausing the wrong media yet...
That isn't a bug. High Sierra was programmed to control whatever media is currently "active". If iTunes is the only program active, it will control iTunes. If you have a YouTube video playing, it will control YouTube. There is a program that will revert back to the Sierra way of controlling iTunes.

First OSx came 2001 and current version is just an evolution of that made by updating it yearly
Yeah, it's annoying. The 10.x versions are always quite large updates that break a lot of third-party stuff and introduce bugs. I'm mainly sick of all my software breaking every single year. Like, great, I just can't use my Photoshop anymore... why the **** did I update. Oh, to use the new Xcode and to have the small security fixes.
