Apple Confirms No (Default) ZFS In Leopard
javipas writes "Despite recent rumors about the possible inclusion of ZFS as the filesystem of choice for MacOS X 10.5 'Leopard', an Apple executive has denied this possibility. Brian Croll, senior director of product marketing for the Mac OS has as much as said 'ZFS is not happening ... Croll declined to comment on statements made last week by Sun Chief Executive Jonathan Schwartz, who said the use of ZFS would be announced at the Apple Worldwide Developers Conference in San Francisco. Upon further questioning, Croll would only confirm that Apple had never said ZFS would be a part of Leopard. A representative with Sun did not have any immediate comment.' Users of the future operating system will have to keep working with HFS+, a filesystem that is almost ten years old now." Update: 06/12 19:57 GMT by KD : An Apple spokesman contacted InformationWeek with a correction, which they ran as a comment on their original story: What Apple meant to say was, "ZFS would be available as a limited option, but not as the default file system."
"Upon further questioning, Croll would only confirm that Apple had never said ZFS would be a part of Leopard."
Obviously they haven't said anything about ZFS being included, but that doesn't imply they aren't including it. Sun might just have said something they weren't supposed to, or ZFS might just have been considered for inclusion. Who knows...

ZFS is in the WWDC Leopard build. It's currently configured for read-only, although full functionality is in there. Write ability is disabled for stability/integrity issues. /System/Library/Extensions:

What he declined to comment on was the comment made by the Sun executive, but he did comment on ZFS itself.
"Sufferin' succotash."
On the one hand, MS was telling everyone for years about their new filesystem named WinFS. Actually if you consider the capabilities of WinFS and not just the name, MS promised that type of technology in Cairo over 10 years ago. On the other, Apple never said it was experimenting with ZFS much less that it was going to use it. A Sun exec said Apple would use it in Leopard based on the fact that Apple entered into an agreement to use ZFS. My viewpoint is that although Apple got rights to use it, that doesn't mean that they were going to base Leopard on it. I'm sure they experiment with all sorts of software including filesystems. Maybe in the future, Apple might replace HFS+ with ZFS but not right now.
Well, there's spam egg sausage and spam, that's not got much spam in it.
It was in the Leapord beta. I think that's a fairly good reason to make that assumption.
Beware of bugs in the above code; I have only proved it correct, not tried it.
First off, screen sharing appears to still be supported in the OS:

Additionally, the button for screen sharing is still present in the ichat screenshots:

...and HFS+ is just an incremental update from HFS - adding stuff like journaling and support for larger drives, long unicode file names, and some unixisms like inodes and /dev and hard links and case sensitivity.
So you can really say that HFS+ is almost 22 years old now.

Its description has been moved to the "Finder" page at http://www.apple.com/macosx/leopard/features/finde r.html in the "Closer connections" paragraph.
"By clicking on a connected Mac, you can see and control that computer (if authorized, of course) as if you were sitting in front of it. "
It's now integrated into the Finder (Closer Connections on the Finder page).

Have you actually *used* ZFS? It is not CPU intensive in the least. I've run it on a 700MHz PIII with no problems. From the developer's mouth: "Assume 1 2GHz Opteron for every 200 MB/s, including ZFS *and* the NFS stack". 200 MB/s is an order of magnitude (10x) faster than any hard disk installed in a desktop or laptop. And, that's for a continuous I/O load, which most users never see.
If you're having CPU issues with ZFS, you're in the HD video business, in which case you'll have a dual CPU machine anyway.
If you disable the data checksumming, you have removed one of the main advantages of ZFS. You also can't (yet, anyway) disable metadata checksumming. (Not all of the advantages, of course -- the volume management is very well done, and it's got more space available than HFS+ does. But most home users don't run into those limits.)
People doing video editing on the Mac tend to suck up every single bit of bandwidth available; Apple has done a lot of work to give them that. And they continue to want more bandwidth. HFS+ lets you do pre-allocation of files, and direct-to-disk I/O. ZFS doesn't.
Of course, most home users won't run into that, either. So it's largely a wash. Except for the data integrity, which you're suggesting be turned off, and the volume management.
The InformationWeek editor has posted this ...
As to the news, it seems that Croll mispoke a couple of times when asked about ZFS in Leopard. Despite direct questions about Sun CEO Schwartz's claims that ZFS is there, Croll flatly denied the reports to two of our reporters in a 1:1 interview.
An Apple spokesperson called us Tuesday seeking to clarify Croll's statement. Croll was apparently supposed to indicate that ZFS would be available as a limited option, but not as the default file system."
We are now writing a separate story to note Apple's mis-statement and hopefully to reveal more about how ZFS would work in Leopard.
We'll update you here when that story is live.

Do a quick Google search for their relative market shares. Apple has 4-7% of the US market sales. ATI has 22-26% of US market sales. If you want to look at global market sales, Apple drops to 3% and ATI drops to 8%, since globally the high end market makes up a much smaller chunk of that market then it does in the US, with on the board solutions predominating.
Now before you waste my time with redefining the market definition to exclude on the board solutions, remember that is the percentage computers we're discussing since that provides the relative size of Apple as a customer. Getting the 5th largest computer maker in the US to sign on to include your product and not to include your competitors (as most large manufacturers do) would be big win for any of the players. Losing it through a move that does not even make any money is sheer idiocy.
If, at some point in the future Apple does do business with ATI again, do you think ATI will take keeping things confidential seriously or do you think they'll stupidly lose a giant contract while gaining nothing again?
If? The issue with Jobs dropping ATI occurred in 2000. Apple has been dealing with ATI for several years now (though since the AMD/ATI merger, Apple seems to be using NVidia GPUs in new products).
