Bertrand Serlet, Apple’s
senior vice president of Software Engineering, describes, "Snow
Leopard builds on our most successful operating system ever and we’re
happy to get it to users earlier than expected. For just $29,
Leopard users get a smooth upgrade to the world’s most advanced
operating system and the only system with built in Exchange
The new OS is set to go head-to-head with
Microsoft's Windows 7 and delivers many major improvements for Mac
Over 90 percent of the 1,000 core programs in OS X had
their performance tuned and improved, according to Apple. Many
-- namely, Finder, Mail, iCal, iChat, and Safari -- were moved from
32-bit into a 64-bit world, which boosts memory performance, among
other things. Apple says that its Finder is "more
responsive", its Mail client is twice as fast, and Time Machine
is 80 percent faster at its initial backup.
Apple includes the
new QuickTime X and Safari 4 with the OS. Apple says that the
new version of Safari is more resistant to plug-in crashes and 50
percent faster at general web browsing (Safari recently received the
accolade of being listed by Futuremark as tied with Google's Chrome
as the fastest browser).
The size of the installation has also
been cut in half freeing 7 GB.
Apple is pushing a
couple of new technologies with Snow Leopard. The first is its
Grand Central Dispatch (GCD) a technology designed to optimize
multi-core usage. Another new tech is OpenCL, a C-based open
standard, which looks to provide heterogenous processing on both GPUs
Ironically, one of Apple's biggest selling point
with the new OS comes from competitor Microsoft. Apple
explains, "Snow Leopard is the only desktop operating system
with built in support for Microsoft Exchange Server 2007, and it
allows you to use Mac OS X Mail, Address Book and iCal to send and
receive email, create and respond to meeting invitations, and search
and manage contacts with global address lists. Exchange information
works seamlessly within Snow Leopard so users can also take advantage
of OS X only features such as fast Spotlight searches and Quick Look
Unlimited licenses of Snow Leopard are
available for $499, half the price of an unlimited pack for Leopard.
The new OS will start shipping this Friday to customers that
pre-order. Amazon.com has already been holding an unofficial
pre-order for the last couple weeks and saw Snow Leopard jump
to the top of its software sales charts.
Server will launch on August 28, as well, alongside the new consumer
OS. The Server edition comes with Podcast Producer 2 and Mobile
Access Server and costs $499 for an unlimited license.
quote: The 32-bit kernel fully supports 64-bit applications, all system libraries that 64-bit applications use are fully 64-bit, and 64-bit applications have a full 64-bit virtual address space of 16 exabytes available to them on Mac OS X. The primary benefit of a 64-bit kernel is to improve the efficiency of accessing over 32GB of RAM.
quote: there is no conceivable reason to only allow 2GB RAM on hardware that is suppose to be high end.
quote: Welcome to 64 bit Apple users, please commence your 2 year waiting period before suitable 3rd party drivers become available for your hardware.. at that point perhaps everyone will see true 64 bit.
quote: Apple is trying to pull a fast one over its customers, they have been claiming something to be true for months and have taken back on that promise. While I would still upgrade to SL, if I were an Apple user, I would not be very happy right now.
quote: I agree it is a good move, but I feel unless you move to newer hardware, you're pretty much SOL.
quote: There is no reason why my Macbook can't address 8GB of ram with a 64-bit OS, but Apple went ahead and made sure to cripple it to only work with a maximum of 2GB of ram, which sucks. I have a laptop that cost $1700 at the time it was purchased, but it was crippled by the company.Dells, HPs, Lenovos, etc with the same hardware from the same period could support 8GB of ram, provided you have a 64-bit OS.
