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."
