Apple today seeded the first beta of an upcoming OS X 10.11.5 beta to public beta testers, just a day after releasing the first OS X 10.11.5 beta to developers and two weeks after releasing OS X 10.11.4, the fourth update to the OS X 10.11 operating system.

The new beta is available through the Software Update mechanism in the Mac App Store for those who are enrolled in Apple's beta testing program. Those wishing to join the program can sign up on Apple's beta testing website.

Most of the updates to OS X 10.11 have been minor in scale, and OS X 10.11.5 is no exception. The update appears to focus on under-the-hood bug fixes, security enhancements, and performance improvements with no obvious outward-facing changes.

Has the public beta testing program really made a significant improvement leading to a more stable OS in a shorter amount of time? From the numerous comments from users, it seems like El Capitan is one of the buggiest versions of OS X ever.
And do you know how many negative comments were present for the last four or five versions of OS X? It seems like every time, people complain about the latest and look back at the previous version and say "it was all better before".

While I doubt you will find stats on negative comments, or prove otherwise , coming from a development background, switching to annual updates of OS X and releasing a new version of OS X each year, results In feature development and not maintaince , hence people complain about bugs.

I can definely say that an OS 2-3 years in is a lot more stable and bug free than a new OS every 12 months . Current release schedule is not realistic to meet feature development , let alone correcting outstanding bugs.

Window 10 will be very solid this year, while we get a new version of OS X with new bugs.

Although I agree in general, I have to say that my experience has been that OS X is stable out of the gate. There have been very few bugs at the core. Most of the complaints are one off issues in a feature.

And you are right about broken window 10. It will be a solid year for ms as they will know your activity from behind the scene.
