Apple's Leopard will use ZFS, but not exclusively: "Blog: Apple confirmed statements by Sun's Jonathan Schwartz that Leopard will use ZFS, correcting an executive who Monday suggested otherwise."

Apple has clarified reports regarding the use of Sun's ZFS file system in Leopard, confirming that ZFS is present in the operating system but that Apple has not yet made it the default file system.
Last week, Sun CEO Jonathan Schwartz said that Apple planned to announce a switch to ZFS as the basic file system for Mac OS X at its Worldwide Developers Conference. That announcement didn't arrive on Monday as part of the WWDC extravaganza, and then Information Week reported Monday that an Apple executive denied that ZFS was present in Leopard.
The full story emerged on Tuesday: apparently the executive misspoke. Leopard will support two file systems, the HFS+ technology currently found in Mac OS X, as well as ZFS, a next-generation file system developed by Sun and unveiled in 2005. However, HFS+ will remain the default option.
