Yes, it's true. Check Software Update right now. The build is only a 180MB (Update: It appears that the size of the update varies from computer to computer, ranging from 180-380MB) download and not 400MB+ as some people thought it would be. Here are some of the improvements:
Active Directory

* Addresses issues which could hinder or prevent binding Mac OS X 10.5.x clients to Active Directory domains.

AirPort

* Improves connection reliability and stability
* Includes 802.1X improvements.
* Resolves certain kernel panics.

Back to my Mac

* Adds support for more third-party routers, as detailed in this article.

Dashboard

* Improves performance of certain Apple Dashboard widgets (such as Dictionary).
* Addresses an issue in which Dashboard widgets may no longer be accessible after switching to or from an account that has Parental Controls enabled.

Dock

* Updates Stacks with a List view option, a Folder view option, and an updated background for Grid view.

Desktop

* Addresses legibility issues with the menu bar with an option to turn off transparency in Desktop & Screen Saver preferences.
* Adjusts menus to be slightly-less translucent overall.

iCal

* Improves iCal so that it accurately reflects responses to recurring meetings.
* Addresses an issue in which a meeting may remain on the calendar after being cancelled.
* Addresses stability issues related to .Mac syncing of iCal calendars.
* Resolves an intermittent issue in which editing an event with attendees would cause the event to shrink and not register that the event was updated.

iChat

* Addresses an issue with simultaneously-logged in accounts in which iChat sounds generated from one account might be heard in another account.
* Fixes an issue in which iChat idle time is affected by Time Machine backups.
* Improves connectivity when running iChat behind a router that doesn’t preserve ports.
* Enables logged chats from previous versions of iChat to open faster and more reliably.
* Addresses an issue with text chats in which users may be unable to receive messages from the sender.
* Addresses an issue that may prevent rejoining an AIM chat room without reopening iChat.
* Addresses video chat compatibility issues with AIM 6 and third-party routers.
* Fixes an issue with case-sensitivity of AIM handles.

And much much more. Here is the more.

what about compatibility with our hackintosh ?
I think this gonna be the first test for the EFI

no it will not work...wait till someone releases a crack...and are you sure its 180MB? its 341MB for me...

Can we get confimation on the size of this update because the update i have is about 348MB...I believe you can automatically update if you have EFI installed. Can anyone confirm? Im doing this a real mac

Note to all users: mine was exactly 180 MB. This is odd though. On the computers in my house, I got 180MB, 380MB and 341MB. Odd...

And here's a screenshot of the first 10.5.2 Install DVD just for fun

And no, it's not been released yet before anyone asks...
Note: This is for Hackintosh, not real Macs.

341MB here. This is going to be very interesting. I might just hibernate for 2 weeks for all of this hectic confusion to blow over. I'll wake up when all the solutions and patches are figured out for the hacks

yes this will work on real macs

no this will not work on hacks, even if you have EFI+vanilla... there's been some reports of success with EFI+MBR though

and then there's this

What's the ICH7 to ICH9 AHCI Controller option?

It adds the various chipset/controller matches to AppleAHCIPort.kext to support all those controllers without you having to edit it.

~mac.nub

yay, I don't have the GA-P35-DS3L yet but very impatient for it

/me wanna try your DVD

341MB here too, MacBook 2.0ghz C2D.

Finally! Glad to see it released--with the graphics update as well. I have one question, however: is it possible to increase the menu translucency? In 10.5.1, drop down menus were very slightly translucent, 10.5.2 renders them completely 100% opaque. I actually like the translucency and due to the adjustment for 10.5.2, the translucency must be changeable. Perhaps I could increase the translucency even further than in 10.5.1.

What's important is the space it needs to install, and that is 1 Gig. Plus there are two other updates to consider, the graphics update, and the security update. Make sure you do a backup before you install these, and reboot in-between installs

<--- SWEET!

this update f*ucked up my powerbook G4. now the powerbook won't boot, it stucks at the blue screen with 2 cursors.

It jacked up my Toshiba.

My trackpad and keyboard dont work. The "notification" area is all jacked up. and To top it off the system profiler is not able to gather info correctly.

And there was much rejoicing!

is it 9c31?

Yes

Sweet!, Just updated my 17" MacBook Pro and my wife's MacBook (Black). Waiting on the Word on how to update to 10.5.2 on my HacPro.

You need to copy across some of your old extensions that you (should've) backed up before running the installer.

its 180 on my macbook pro

...just waiting for the inevitable "does anyone know when 10.5.3 is coming out?" thread

Installed nice and smoothly on my MacBook Pro.

It worked on my PowerBook G4 12"

I did not update with Sofware Update because I use downloaded installer for al my macs and hacks

Thanks guys

Has anyone seen any improvements with the Leopard Graphics Update package? My SR MacBook's Dock still feels very choppy, and haven't really noticed an overall improvement with the Intel X3100's performance. I was very disappointed with this update, as I was hoping to see this issue resolved. Guess all we can do is keep waiting...

Yes, my iMac now wakes up from sleep and the display actually goes to sleep.

Need for Speed is WAY faster for me.

I actually see no difference whatsoever with this update. I noticed the Stacks thing, but I won't use it. I like my Drawer Stacks. Am I the only one that doesn't see anything new with this?


So when's 5.3 coming out?

Oh damn. lol I did kinda backup some extensions. But then the graphics update totally ruined it. So then I tried to uh...restore it with time machine on the install dvd and now it wont boot. So Ill just reinstall. haha

Same here, but I'm redoing it in the weekend.

This is going to be like the eight millionth time i've had to reinstall leopard. *sigh* oh well. Learing experience.

Hmm... They release 10.5.2 on a Monday and tomorrow is Tuesday, and they love to release new hardware on Tuesdays. Anyone else see what I'm getting at? New MBP tomorrow? Ah, a man can dream...

agreed 10.5.1 worked perfectly for m without any problems so i dont notice any major changes with this till now but im sute they have some internal fixes.

so yeah 10.5.2 > 10.5.1.

You will get a big boost with 10.5.2 graphic update .

Just tried installing on my Hack. Crashed during the installer..

I will install it once a successful tutorial is posted hopefully till then aidos 10.5.2 .

There is also a Leopard Graphics update download now.

Very little performance increase on my PowerBook but that's good.

Weird at the Stacks though:

I just wanna tell u about 2 issues so far

1. when I go to system profiler / Hardware i get: "There was an error while gathering this information."

2. My 2.8 ghz C2D is reported as 3.8 ghz C2D


anybody had this same issue ?

Just put the OLD AppleSMBIOS.kext back!!

SticMAN

would this work with amd based systems?

Just open that link and read:
"of course it’s all for intel core 2 based cpus and intel mobos. and pc_efi."


but,

"other users can use 10.5.1 kernel/system.kext with 10.5.2 system (like amd users or pentium-d)"
