Running 10.9...don't see much difference

You're a brave soul installing beta 1 on your main install. Let us know if anything does not work (though I will certainly wait for a few more betas at least.)

 

I'm running it and there is quite a bit different... Finder tabs is a huge difference all by itself. Also, there is Maps.

So far it seems to be running very well. I'm on a mid-2009 13" MBP. I haven't run into anything wonky yet.

 

Huh, Safari is a bagillion times faster (than Safari or Chrome)
Maps is bad ass. Calendar integration with traffic is nice.
Finder Tabs are also nice.

 

Hate to be a party pooper, but aren't you breaching the NDA by discussing features of the beta here?

OR did you get a torrented version already?

 

The only reason I'd like to try the beta is to see if the UI lag persists on the rMBP.

What is the OP running it on?

 

No, because Apple does the same:
http://www.apple.com/osx/preview/

 

Never understood why people expect all their 3rd party crap to work with the first beta release of an OS.

Why not just keep 10.9 clean and run it through its paces first?

 

I'm seeing better performance, and a few cool little bugs (at least I hope they're bugs)

 

Bugs? Details please.

 

-Spotlight has had an off and on relationship with the "Apps using Significant Power" spot. At first, it was because it was indexing again. Then it stopped, and even a restart quickly had it using a larger amount of power
-Shutdown is slower than in Mountain Lion for me. This might not be a bug, but I hope it is.
-When I put in "WebKit" into my Spotlight (which the nightly doesn't work yet folks, but that's expected), I get multiple versions of it that do nothing. Seriously, they open up to saying that the application isn't there. Kind of afraid to delete any of them, though, on the off chance that one of them is powering the main Safari.

Small things, not enough to make me want to go back. It looks nice, responds nice, and is overall better than Mountain Lion already. Also, Maps is a bit slow to open... but that's just nitpicking.

 

Uh oh. I was hoping for faster shutdowns and boot ups.

 

Oh, boot up is slightly faster.

Shutdown, though? Ugh.

 

Shutdown has been terrible for me so far.

 

It's not even a beta. It's a developer preview build (per-beta).

 

That is a beta in all recent Apple speak… Let's not kid ourself on that.

 

No it's not, all OS X betas are called "Betas" not developer previews.

It seems that since OS X resources were pulled of to work on iOS 7, Mavericks is behind schedule and not into beta phase yet.

 

No, actually the poster was right, Apple 'Developer Previews' of OSs are the equivalent of beta releases, internal testing only for 'alpha' and true 'beta' releases, then what is let out to developers is more or less done. See Mountain Lion and previous releases - no 'beta' release just 4 (IIRC) developer previews then I think the GM. Actually was a pretty smooth process just needing fresh install for the public release.

 

That's OK. The feeling is mutual.

 

If that were true, both Lion and Mountain Lion have never been in Beta.

Apples Developer Previews are their Betas. It's just that.

 

Mavericks (10.9):Mountain Lion (10.8) = Snow Leopard (10.6):Leopard (10.5)

To power users, Snow Leopard represents the pinnacle of stability and performance. Mavericks aims to give those folks reasons to upgrade, with significantly improved memory management (DP1 had some memory management bugs, but DP2 has been very solid to me so far), longer battery life, and improved performance throughout.

To that end, while number of "visible" improvements are not significant, there are few improvements that even casual users may appreciate:

• iCloud Keychain (synchronize login password and credit cards between iOS and OS X)
• New apps: Maps (included), iBooks (to arrive in Mac App Store)
• Multiple displays: Menu bar and full screen apps on multiple displays
• Finder: Tabs, tags
• Less skeuomorphism in Calendar, Contacts, login screen
• Activity Monitor: Energy report

 

Prove it sir.

 

Please, erase.
