Guys Opened this thread for voting and sharing info about best mac operating system from OSes ..
Everybody are Welcome


- Tiger

- Leopard

- Snow Leopard

- Lion
My Best

-Mountain Lion

EDIT : Added Tiger version upon mentioning here ;)

EDIT 2 : If anybody interested in even deeper history.. here :)
Looks like Mountain Lion is OS X 9 so Windows is behind :D


1. Mac OS X “Cheetah” (10.0)
Time: March 2001—September 2001
The initial version was slow, incomplete, and had very few applications available at the time of its launch, mostly from independent developers. While many critics suggested that the operating system was not ready for mainstream adoption, they recognized the importance of its initial launch as a base on which to improve. Following some bug fixes, kernel panics became much less frequent.

2. Mac OS X “Puma” (10.1)
Time: September 2001—August 2002
It had better performance and provided missing features, such as DVD playback. On January 7, 2002, Apple announced that Mac OS X was to be the default operating system for all Macintosh products by the end of that month.

3. Mac OS X Jaguar (10.2)
Time: August 2002—October 2003
It brought great performance enhancements, a sleeker look, and many powerful enhancements (over 150, according to Apple), including Quartz Extreme for compositing graphics directly on an ATI Radeon or Nvidia GeForce2 MX AGP-based video card with at least 16 MB of VRAM, a system-wide repository for contact information in the new Address Book, and an instant messaging client named iChat. The Happy Mac which had appeared during the Mac OS startup sequence for almost 18 years was replaced with a large grey Apple logo with the introduction of Mac OS X v10.2.

4. Mac OS X Panther (10.3)
Time: October 2003—April 2005
In addition to providing much improved performance, it also incorporated the most extensive update yet to the user interface. Panther included as many or more new features as Jaguar had the year before, including an updated Finder, incorporating a brushed-metal interface, Fast user switching, Exposé (Window manager), FileVault, Safari, iChat AV (which added videoconferencing features to iChat), improved Portable Document Format (PDF) rendering and much greater Microsoft Windows interoperability. Support for some early G3 computers such as “beige” Power Macs and “WallStreet” PowerBooks was discontinued.

5. Mac OS X Tiger (10.4)
Time: April 2005—October 2007
Apple stated that Tiger contained more than 200 new features. As with Panther, certain older machines were no longer supported; Tiger requires a Mac with a built-in FireWire port. Among the new features, Tiger introduced Spotlight, Dashboard, Smart Folders, updated Mail program with Smart Mailboxes, QuickTime 7, Safari 2, Automator, VoiceOver, Core Image and Core Video. The initial release of the Apple TV used a modified version of Tiger with a different graphical interface and fewer applications and services.

6. Mac OS X Leopard (10.5)
Time: October 2007—August 2009
It was called by Apple “the largest update of Mac OS X”. It brought more than 300 new features. Leopard supports both PowerPC- and Intel x86-based Macintosh computers; support for the G3 processor was dropped and the G4 processor required a minimum clock rate of 867 MHz, and at least 512 MB of RAM to be installed. The single DVD works for all supported Macs (including 64-bit machines). New features include a new look, an updated Finder, Time Machine, Spaces, Boot Camp pre-installed, full support for 64-bit applications (including graphical applications), new features in Mail and iChat, and a number of new security features. Leopard is an Open Brand UNIX 03 registered product on the Intel platform. It was also the first BSD-based OS to receive UNIX 03 certification. Leopard dropped support for the Classic Environment and all Classic applications. It was the final version of Mac OS X to support the PowerPC architecture.

7. Mac OS X Snow Leopard (10.6)
Time: August 2009—July 2011
Snow Leopard focuses on “under the hood” changes, increasing the performance, efficiency, and stability of the operating system. For most users, the most noticeable changes are: the disk space that the operating system frees up after a clean install compared to Mac OS X 10.5 Leopard, a more responsive Finder rewritten in Cocoa, faster Time Machine backups, more reliable and user friendly disk ejects, a more powerful version of the Preview application, as well as a faster Safari web browser.
Mac OS X v10.6 also features Microsoft Exchange Server support for Mail, iCal, and Address Book, new 64-bit technology capable of supporting greater amounts of RAM, an all new QuickTime X with a refreshed user interface and more functionality that used to be only available to QuickTime Pro owners.
Snow Leopard only supports machines with Intel CPUs, requires at least 1 GB of RAM, and drops default support for applications built for the PowerPC architecture (Rosetta can be installed as an additional component to retain support for PowerPC-only applications).

8. Mac OS X Lion (10.7)
Time: July 2011—July 2012
It brought developments made in Apple’s iOS, such as an easily-navigable display of installed applications (Launchpad) and (a greater use of) multi-touch gestures, to the Mac. This release removed Rosetta, making it incapable of running PowerPC applications.
Changes made to the GUI (Graphical User Interface) include the Launchpad (similar to the home screen of iOS devices), auto-hiding scrollbars that only appear when they are being used, and Mission Control, which unifies Exposé, Spaces, Dashboard, and full-screen applications within a single interface. Apple also made changes to applications: they resume in the same state as they were before they were closed (similar to iOS). Documents auto-save by default.

9. Mac OS X Mountain Lion (10.8)
Time: July 2012
It will incorporate some features seen in iOS 5. These include Game Center, support for iMessage in the new Messages messaging application, and Reminders as a to-do list app separate from iCal (which is renamed as Calendar, like the iOS app). It also includes support for storing iWork documents in iCloud. It is scheduled to be released in July 2012. Notification Center, which makes its debut in Mountain Lion, is a desktop version similar to the one in iOS 5.0 and higher. Application pop-ups are now concentrated on the corner of the screen, and the Center itself is pulled from the right side of the screen. Mountain Lion also includes more Chinese features including support for Baidu as an option for Safari search engine, QQ, and services for Mail, Contacts and Calendar, Youku, Tudou and Sina Weibo are integrated into share sheets.

Snow Leopard, no question. The most stable OS, with most of the upsides of Lion. Only thing missing in 10.6 is the recovery partition.

what is the criteria for "best"? Cheapest, more features, greater stability, runs latest hardware, more likely to be supported in the next 2 years......??????

Leopard, and Lion are the best for me even if I am now using Mountain Lion, didn't see too much of a differences with Snow Leopard from the original Leopard.

But it was the best and most stable OS I ever used.
My Intel Macs had more kernel panics in one year than my iBook had in four years, and it was rarely hardware related.

+1 for Tiger. Made it to 10.4.11 (cf 10.7.5) so clearly it was doing something right. Alongside Leopard, it was the last of the 'traditional' OS X updates, and the OS that brought Intel - along with many users - into the world of Macs.

Plus pinstripes and the blue apple logo were awesome.

Considering you're missing over half the iterations of OS X I'd say that this is beyond pointless. Also, ever heard of a poll?

Nothing much has changed since Snow Leopard. Lion was an alright upgrade, but ML was pointless - I don't even know what it does beyond notifications and that silly gatekeeper program. Would definitely prefer the greater battery life.

integration with iCloud. That alone made me upgrade (and that it was free for me through the up-to-date program ;) )
