Apple's public betas of iOS 9, OS X El Capitan are now available [u]
Apple on Thursday launched the first public betas of OS X El Capitan and iOS 9, giving the public an early glance at the operating systems before they officially debut this fall.

The company warns that because the platforms are in beta, some apps may not work properly. Before installing, users are strongly urged to make backups of their data in case problems arise with either apps or the operating systems themselves.
The betas are available through the company's Beta Software Program website for registered participants.
The new code should be based on third developer betas which were released on Wednesday alongside a new seed of watchOS 2. The El Capitan build contained known issues with two-factor authentication, restoring Time Machine backups for Mail, and importing iPhoto and Aperture libraries into Photos, among other bugs.
Before installing the new software, see AppleInsider's ongoing, in-depth Inside iOS 9 series.

The iOS public beta is out too. That I'll put on an iPad, as I have a couple I can use. Frankly, I'm more excited by that for my iPad Air 2.
Prepare for the inevitable raft of "my computer has been bricked" comments from people who are not paying attention.
Beta's are pretty exciting, and Apple wouldn't release a public beta is it was really screwed, as early betas always are. Still, it is a beta, and with the gotchas Apple did announce, it's fairly risky. And what about those they haven't yet found?
I've done a lot of beta testing for Adobe and others over the years, and it can be pretty dreary and frustrating until late in the process.
But I am backing my iPad Air 2 to my Mac now, in prep for the iOS beta, which is much more interesting and exciting. I do have another iPad—just in case. But the full backup will allow a downgrade should that be required.
I'm not sure how Time Machine would handle a downgrade on a Mac for a beta though, as I've never done it.

The big problem for the average person is the apps they use. There are plenty that don't work properly with the developer beta of El Capitan, and that likely won't be any different with the public betas. So people need to understand that they shouldn't install the beta on a machine where they need to do day-to-day work.
That is a very informative post! I'm sure many will thank you for this.
Won't that be useless if Apple doesn't sign the OS anymore? That happened to the watch, right?
It's installing, and restarting now.
It feels odd. Almost all of my posting is done on my iPad. This is the first time in a long while that I'm doing it on my Mac Pro.

Yeah. But I don't think they'll do that, as this is a beta. 8.4 was a release. Don't remember what they did with the watch.
It's installing slooowly.
"When Apple released the first beta of watchOS 2.0 last month following WWDC, users were surprised to learn that there was no way to downgrade from the beta build to the more stable Watch OS 1.0.1. Users tried a variety of different methods, but were ultimately left with one option: send their Watch into Apple and allow them to do the restore. With today’s launch of watchOS 2.0 beta 3, Apple has officially confirmed that there is no way to downgrade to an earlier version of watchOS without sending your device into Apple."

The Apple Watch update causing some consternation is also a beta.

Ok, whatever. But on their site, they said you could downgrade these. Do a "restore" with your backup.
it's done. After fooling around with it for a bit, I'll try posting again with it.

But that was for a developer beta. This is a public beta with a much wider (and less technical) audience. I'm fairly certain that they'll allow you to downgrade.
If you don't have a machine that isn't in the path of work need, I strongly advise people to hold up on this. Being the first kid on the block with the new OS isn't going to be great if you can't get things going because a bug prevents what you need from working.
That said, if you do have a backup Mac, don't hesitate to try 10.11. I've found it pretty stable...not bug free, but stable.
Ok, I'm back on my iPad. Boy, the keyboard does seem odd. Lower case characters as normal does seem just so strange. I never had a problem with the caps key, and could never understand why people did. But this seems to work well.
I agree, if you have an additional machine, you should try this, as long as you don't care if things get a bit bolloxed up.
Apple's beta website is getting absolutely hammered. Can't even open the page.
It's a separate enrollment.
