About Mac OS X Snow Leopard

Mac S X Snow Leopard (version 10.6) is the seventh and current majorrelease of Mac S X, pple's desktop and server operatingsystem forMacintosh computers.

Snow Leopard was publicly unveiled on June 8, 2009 at the ppleorldwide Developers Conference.

n ovember 10, 2010, it was released as 10.6.5 model worldwide, andwas made available for purchase from pple's website and its retailstores at the price of US$29 for a single-user license.

The goals with Snow Leopard were improved performance, greaterefficiency and to take advantage of modernMacintosh hardware.



1. efined, not reinvented.

2. ew look, new features .

3. Quicker Time Machine backup

± Time Capsule

Tools for backup data with its

Wireless technology.

± TimeMachine

utomatic backup for ourMac



Features of Time Machine

1. Set it, then forget it

Connect the drive and assign it to Time Machine and enjoying peace

of mind time machine will automatically do his job of backup data.

But what makes Time Machine different from other backup

applications is that remembers how your system worked on a given

day.

2. Go back in time

Say we accidentally deleted a file we meant to save on that

condition the feature of Mac will provide us the security to go backin time and save the file.

3. Migration with style

Style can be changed according to the time set the time machine

for the great appreance of the operating system.



4. Faster to wake up and shut down.

5. Faster, more reliable installation.

6. Smaller footprint: Snow Leopard takes all

about 7 B of Hardisk for installation purpose.

7. More reliable, higher

resolution on iChat: Having

a video chat using iChat is

more reliable and more

accessible than ever in Snow Leopard.

8. Automatic time zone setup: If we are traveling around the world, the last thing we

want to worry about is whether our computer is set to the correct time zone. Using

the Core Location technology, it locates knownWi-Fi hotspots to set the time zone

automatically, so youll always know the right time no matter where we are.



9. Easy PDF text selection.

10. Faster, more powerful Safari.

11. More reliable disk eject:

Snow Leopard improves the reliability of ejecting discs and external drives.Sometimes when an application or process is using the files on a drive,

Mac S X prevents you from ejecting it thus protecting the system from

various accidental crashes.



Advance Technology 01 .

TheMac Snow Leopard is purely 64 bit perating System.

The entire computing industry is moving from 32-bit to 64-bit

technology, and its easy to see why. TodaysMac computers can

hold up to 32 B of physical memory, but the 32-bit applications

that run on them can address only 4 B of M at a time, but 64-bit computing

shatters that by enabling applications to address a 16 billion gigabytes of

memory.

02. Built-in applications are now 64-bit:

The mac Snow leopard S has all system applications including the Finder,

Mail, Safari, iCal, and iChat are now built with 64-bit code.

03. Ready for the future.

The 64-bit support in Snow Leopard makesMac S X completely ready for

whatever computing enhancements might arrive in the future. For example,

Snow Leopard is ready to support up to 16 terabytes of M about 500

times more than todaysMac os.



04. More secure than ever : Another benefit of the 64-bit applications in Snow

Leopard is that theyre even more secure from hackers and malware than the

32-bit versions.

05. 32-bit compatible.

To ensure simplicity and flexibility, Mac S X still comes in one version that runs

both 64-bit and 32-bit applications. But the developer of Mac S has stated

theirMac S as ure 64-bit perating System.

06. Familiar, C-based language with industry support.

With penCL stands for pen Computing Language. TheMac S

has a full support for the programming based Languages like C based language.

07. Power of UNIX. Simplicity of the Mac.

The power of U IX S can be seen inside theMac

S in the case of working of security but in

appreance it has the functionality of Mac.



Windows on a Mac

1. Office on your Mac

VariousMicrsoft application can be run on a pc with havingMac S

installed on that.

2. Microsoft Exchange Server support

A native version of Microsoft ffice is available forMac S X, and itfeatures aMac-friendly interface that lets you create documents withWord, presentations with ower oint, and spreadsheets with Excel justlike on aWindows C.

3. It runs Windows, tooWe can install multiple operating system in a C having Mac S.

such as windows S andMac S

4. Connect to PCs over a network: provide the functionality to connect our

pc over a network pc usingM

ac S.



Hardware equirement

� Mac computer or an Intel processor with a 64-bit processing.

� equires a 1.6 Hz processor or faster for improved performance.

� 1 B of minimum am memory.

� 10 B of available Hardisk space for installing the full version of Mac S X

Snow Leopard.

� DVD drive for installation.

� Some features require a compatible Internet service provider; fees may

apply.

Advantage of MAC OS

A. lug & lay : TheMacintosh computer's true " lug and lay" capabilitiesmake adding hardware cards easy.

B. Adding eripherals : TheMacintosh computer's built-in SCSI port makes it

easy to add peripherals.

C. Easier Installation : TheMac S is easier to install thanWindows.

D. o DLL roblems :Windows "DLL" files cause many problems but in Mac

S there is no such DLL problem occures.

E. Better FolderManagement : TheMacintosh has superior folder

management compared withWindows



F. Fewer Viruses :Macintosh hosted viruses are much less common than

viruses specific toWindows and D S. The Anti-virus esearch Centre, a

Symantec web site dedicated to tracking existing viruses on both Macintoshcomputers and Cs, shows that there are more than 8,000 C viruses in

existence, with two or three new ones appearing every day. In contrast, there

are currently only 47 known viruses specific to theMac S.

. Faster Performance : It's easier to work with graphics and multimediacontent on the Macintosh.

H. Games Work Better :Macintosh games do not suffer from the driver

problems thatWindows games do. Because so many games on the Windows

platform have unique drivers for running sound cards and other devices, thedriver difficulties encountered by the averageWindows user are well known. v



Disadvantages of MAC operating system

M

ac S is designed to work on limited computers.

Most often they are designed to run on Apple hardware therefore we can say

thatMac operating system is really compatible but only for Apple computers.

Mac S is really very compatible to Apple Cs and Laptops. Apple Cs andlaptops are on the other hand very expensive.

Mac operating systems are not for everyone they are mostly used by graphic

designers.

To install aMac S it require more of hardrive space, it takes more Hardisk

space for installation and for working purpose.



Hence trying to install any of the windows applications like Adobehotoshop onMac X would go all in vain.

TheMac S versions need most advance and latest hardware in order to

run.

Mac operating system is considered really secure this I because there are

few number of users till now. If however the number keeps on increasing

day by day then we might face serious security risk even with this

operating systems well.



What's t he Difference Mac OS and W indows Operating System?

S.no Mac OS Windows

01. Mac first version was released in the year

1980s.

Windows was released in 1985 and

was at least inspired from the earliest

Mac S

02. Mac isdesigned more for graphical and

multimedia functions and tends to run

better thanWindows doing so.

Windows, however, is much better withstatistical applications as well as office

applications. It also seems that Windows

is easier for the user to customize,

Machado explained.

03. Mac S made it easier for developers to

assure compatibly and reliability.

However, it has also limited the size ,

which stood at about 30 million

Microsoft emphasized getting as large a

user base as possible for Windows. ow,

somewhere around 90 percent of

computer users runWindows.



S.No Mac OS Windows

04. Mac is an operating system

microkernel CarnegieMellon University

developed to support operating systemresearch. The basis of theMac S X is

still the core built by CarnegieMellon.

"Windows was built around

networking. Its foundation is on highly

modifiable DLLs (Dynamic LinkLibraries) to support many applications

and a registry file for multiple

configurations.

05.M

ac S -- easier to use, nicer to lookat, safer (less people looking for holes

in the S).

Windows -- when combined with acomputer purchase, huge user support

network, easy to customize and repair,

support for a gazillion hardware and

software extensions

06. S X is a Unix based operating system

with a UI which is more user friendly

thanWindows for many users.

Windows is prevalent in business

environments, and has differing

architectures based upon which flavor

is installed (there are vast differences

between 3.11, 95, 2000, X , Vista, and
