Supplemental update for El Capitan beta fixes problems with 32-bit apps
Just one day after launching a public beta of the operating system, Apple has released a "Supplemental Update" for OS X El Capitan, fixing a bug that could cause some 32-bit apps to crash.

The update is available to both public beta testers and people with the third developer beta, which was seeded on Wednesday. Either version can be downloaded through the Mac App Store's Updates tab.
El Capitan users can also download a minor update to the OS' "Samantha" voice, improving clarity and pronunciation.
Because El Capitan is still in a pre-release phase, it's wise to make backups before trying the beta and avoid using it on mission-critical Macs.
The final version of the OS should launch for free sometime this fall. The software is mostly a refinement of Yosemite, but does include new features and refinements such as Split View, performance boosts, expanded search functions, pinned Safari tabs, and an easier incarnation of Mission Control.

Life became hell.
It took me two weeks to recover from that crap. Previously, I would install beta applications when available, but never again since getting burned by Win 97.
I have faith that Apple would do a better job than Microsoft with a beta, but not enough to actually install it.
RULE: No beta operating systems if you actually need the computer to work.
I suppose one could set up an alternate boot partition to try it out. Even then, I would never use it to access live data.
But that's just me.
So far, so good. El Capitan works like a hot diggety-dog.
I remember way back in the day, I installed Windows 97 beta (the eventual shipping version was Windows 98).

No way I'd ever install one of these unless I had a backup Mac.
There are plenty of options which don't require having 2 Macs. I personally have the developer beta installed on a high speed USB 3.0 flash drive and just boot back and forth.
Well you can alternative boot drives.!

Run it in a VM like Fusion or Parallels. No reboots necessary.
You wouldn't install it if the computer is used for work outside of development that is for certain and frankly Apple strongly suggests not installing it on production hardware. However beyond that El Capitan has been wonderful and is already a strong upgrade over Yosemite. I'm running it on a new MBP 13" and I have to say it will be well received when it goes stable and is released. iOS 9 on the other hand has a long long ways to go.
If your computer is making money for you installing a beta OS or even upgrading to a new released OS, is foolish without considering all potential issues. However that doesn't mean that running a beta is a bad thing. The public testing is in fact very useful, even an old man like myself can find plenty of valid bug report to file. It is actually pleasing to have those bugs resolved too.

The only concern here is to ensure the VM you're using fully supports it. I know VMWare and Parallels work pretty quickly to support new OSes, but that doesn't mean Apple won't break compatibility with an update. It is a beta OS after all.

Anyone who runs a beta on their working machine is flat out nuts but you see them in droves on the Apple Discussion Forums complaining about their ‘bricked’ machines and bashing the hell out of Apple.
Assume any beta system will corrupt your machine. It's not rocket science. It's why it's called "beta"!
It is amazing how few don't understand simple English!
On the other hand widespread testing is good thing. I'm actually happy that Apple is engaged in broader beta releases, we just need to learn to ignore the people out there to stupid to understand what a beta is and the users responsibility with installing and testing it.
I think we're approaching the time when it will make sense for Apple to stop supporting legacy 32-bit apps. The transition from 32-bit apps to 64-bit apps began with 10.4 Tiger in 2005 and was reasonably complete with 10.7 Snow Leopard in 2009.
Has anyone tried it? I heard graphics are faster.
So far so good. In all honesty, my experience has been awesome! The graphics are snappier, and everything seems to flow smoother. Even going into Mission Control (which used to be laggy as hell) is stupid fast!
And this is on a MBP 13" 2012 with 8GB of RAM. BTW, the new Beachball is also smoother. ????
Don't forget Windows ME and Vista and 8.0... Or is it just me?
Win 98 SE forever! :-)
It may have started then but there are still a lot of major and supporting apps that are 32-bit, including some Apples own stuff. We aren't ready for this yet.

I hope that 10.11 El Capitan will at least remove any remaining 32-bit Apple legacy code (if there is any other than the libraries required to run 32-bit apps). Keeping around the 32-bit libraries to support 32-bit apps is a drag for Apple and keeping around hardware to support 32-bit instructions is a drag for Intel. We may not be ready to drop 32-bit app support now, but we should be preparing to do so in the future.
