The operating system update is due to debut in the first half of 2005, and Apple executives reckon the open-source nature of the product means it's inherently more secure than certain proprietary offerings. The OS, which wasin March 2001, is is based on the Unix platform.
Bertrand Serlet, senior vice president of software at Apple, said Wednesday that having a greater number of people keeping an eye on source code leads to better software security.
"A lot of security problems derive from the core," he said. With open-source code, "thousands of people look at the critical portions of source code and...check those portions are right. It's a major advantage to have open-source code."
It's yet to be seen whether Tiger will be the target of malware merchants. The Mac OS has had its flaws in the past, but has not seen the number of security scares experienced by rival operating system Microsoft Windows. The worm attack last year was a factor in Microsoft's development of its Service Pack 2 security update for Windows XP, and its software has also taken hits from the Slammer, Code Red and Nimda worms.
Early versions of Tiger are already doing the rounds. Cupertino, Calif.-based Apple handed out one version in June so that developers could get a head start in building applications, said Ken Bereskin, senior director of product marketing for Mac OS X.
Bereskin called the developers' version a "solid copy" of Tiger. But Serlet said there's still a lot of work to be done on the software. For instance, the company has yet to finalize the arrangement of standard "widgets"--the clock, notepad, dictionary and other favorite accessories that a people can click down over the desktop in a semi-transparent layer.
Nevertheless, Apple executives are "very confident," Bereskin said, that they won't have the same deadline grief as Microsoft. Constant delays have plagued the prospective shipping date of, the update to the Windows operating system, and Microsoft developers were moved from working on Longhorn to the SP2 security update, putting the delivery date back even further.
The Mac maker hasn't made it a secret that it believes Microsoft has been borrowing ideas from Apple's previous operating systems. When Apple CEO Steve Jobs unveiled Tiger in late June, the conference building was emblazoned with posters bearing the legend: "Redmond, start your photocopiers."
Regarding Microsoft, Bereskin said: "It's good to see they're studying us closely." When asked whether Apple expects to see MS Widget in Longhorn, Bereskin answered: "We innovate in user features and we get copied a lot."
The Spotlight search feature and some other 150-odd additions that will appear in Tiger were shown off Tuesday at Apple Expo in Paris by Phil Schiller, corporate vice president of marketing.
"Microsoft's date (for shipping Longhorn) seems to keep changing--we just want to say how far ahead of Microsoft we are...we're years ahead of Longhorn," Schiller said.
Spotlight is Apple's big move in the iTunes music store--the little magnifying glass that appears in the top right-hand corner of the screen--but Apple has ramped up its capabilities for Tiger.on the desktop--"the next big revolution in commercial operating systems," Schiller said. Apple's search software works across applications and will sift through both content and metadata, even matching search terms to corresponding text in PDFs. The tool started life as a feature in the
But Apple executives acknowledged at the Expo on Tuesday that even they can't escape the Microsoft orbit. "We have to fit into a Windows world--they're out there and they're all around us," Schiller said.
