Apple Seeds Fifth Beta of macOS Sierra 10.12.5 to Developers [Update: Public Beta Available]

Apple today seeded the fifth beta of an upcoming macOS Sierra 10.12.5 update to developers, one week after seeding the fourth beta and more than one month after releasing macOS Sierra 10.12.4, which introduced Night Shift for the Mac.

The fifth beta of macOS Sierra 10.12.5 can be downloaded through the Apple Developer Center or through the Software Update mechanism in the Mac App Store.

macOS 10
According to the release notes accompanying the beta, the update "improves the stability, compatibility, and security of your Mac."

Apple's release notes don't often provide much insight into what's included in new beta software, so we don't know what features or bug fixes might be built into the 10.12.5 update.

No notable changes or major bug fixes were discovered in the first four betas, but should anything pop up in the fifth macOS Sierra 10.12.5 beta, we'll update this post.

Update: The fifth beta of macOS Sierra 10.12.5 is also available for public beta testers.

Sounds like it's time to upgrade.
Nope, haven't even thought about it!

This machine was bought as a new 'maxed out' top-end monster.

(It was coincidentally rebuilt from the keel up under AppleCare about a year ago giving me a new screen, motherboard and SSHD following some strange power cut outs.)

It handles everything I throw at it and has no OS drag... Yet.

Look after the Mac and it will look after you!

In life, I've found that you don't always need the shiniest and newest of everything all the time...

I'm gonna say majority of people haven't touch more than 50 percent of the features since ML.

I get the horrible feeling we're ramping up for a totally new macOS jump with these stability releases. It's the B team cleaning up making Sierra tight like a drum for it to all go tits up with the next big release. I really wish we got another 2 years of Sierra and stability updates but I feel like this will be one of the last.

Due to the nature of undocumented bug fixes, I presume there were either no bugs fixed or no fixes to be bugged about ?
There wouldn't be any Beta seeded if there were no bugs to be fixed.
I'm gonna say majority of people haven't touch more than 50 percent of the features since ML.
Nobody really uses 'all' of the features on their computers either due to Incompatibility, Third Party options, or just no interest/purpose.

More like Microsoft adopted Apple's model of releasing Windows on a faster model vs one every 3-4 years... Apple's been releasing OS X ~yearly for nearly a decade. 10.4 was my first taste of X and it's been a new drop every ~12 months.
Either your math or your memory is terrible:

10.4 released April 2005
10.5 released oct 2007 (30 months later)
10.6 released Aug 2009 (22 months after 10.5)
10.7 released july 2011 (23 months after 10.6)
It wasnt until 10.8, released july 2012 that Apple started releasing mac os updates on a yearly basis - around the same time a lot of people feel that apple's quality control and software stability took a dip.
IMO, their insistance on rushed annual releases of new OS's has contributed to that decline.
