Mac Os X 10.5 Software Free Download

Sneaking in a few days before its promised September release, the melody-up for Mac OS Ten Leopard costs $29 for current Leopard users, and packs just enough punch to be worth your money. Apple is conscientious to point out that Snow Leopard isn't a consummate system overhaul, but rather a drove of hundreds of smaller refinements to make Leopard run more than gracefully. Hidden among smaller tweaks are some technical improvements that result in a smoother, easier-to-use Leopard with enough for Mac fans to be excited nigh. The user interface and everyday tasks feel faster in full general, although we didn't notice a substantive improvement in awarding operation.

Even if you're not a current Leopard user, the $169 package that includes Snowfall Leopard, iLife, and iWork is a steal for the system upgrade and two of Apple'southward major software suites, not to mention the long-pined-after inclusion of Microsoft Substitution compatibility. Finally you will be able to connect with Exchange Servers (without using Microsoft's Entourage), merely merely if your company is using Microsoft Exchange 2007; many notwithstanding aren't. Snow Leopard is offered on a unmarried install disk--there are no dissever, tiered pricing structures to worry near--and you're getting every characteristic and technical enhancement available in a single install. Unfortunately, for those on PowerPC systems, Snow Leopard just works with Intel Macs.

Installation
Installation of Snow Leopard is dead uncomplicated and (according to Apple tree) up to 45 percent faster than Leopard using a newly designed installer that asks only one question during the process. On our test machine, the process took about an hour, including ii automated restarts. The default setting installs Snow Leopard without tampering with whatsoever of your saved files, music, photos, or documents. Mostly nosotros had no problems, but on one examination motorcar nosotros needed to reinstall the Bone when it had problem rebooting. Fortunately the new installer is designed for safely reinstalling the OS in the issue yous see whatsoever hiccups during your initial installation. On our second effort, the OS installed perfectly on our test car and no files were harmed. PowerPC Macs are no longer supported with Snow Leopard, however; you will need an Intel-based Mac to install the latest Mac OS.

Those who want to do a "Clean Install" (starting fresh by deleting everything for minimal conflicts) yet can, just dissimilar installations in previous versions of previous Mac OS X that offered the clean install as a main option, you'll need to apply Deejay Utility to beginning erase the volume, then run the install. Apple explained to united states that not everyone knows what a make clean install is and often chose it, not knowing that they would lose their files. We're happy with that answer, as long as people withal go the selection in some form.

Apple also claims that Snow Leopard uses 7GB less space than Leopard because of better file compression paired with selective driver inclusion. According to Apple, Snowfall Leopard will locate any missing drivers on the Web for you. Nosotros had no demand of any special drivers during our tests.

New technologies
Apple says a few new technologies in Snow Leopard make it worthy of the upgrade alone, with several features that Apple says will boost performance. Because all new Macs come up with 64-flake multicore processors, multiple GBs of RAM, and high-powered graphics processing units, all the major applications in Snow Leopard--including the Finder--accept been rewritten in 64-scrap to have total reward of the hardware. (The 64-bit technology allows awarding developers to classify more memory to complete tasks so that the software runs faster and more smoothly.)

Apple has also added what it calls the Grand Primal Dispatch that manages information sent to multicore processors in an effort to maximize performance; Apple says the GCD volition speed up whatsoever application task, from processing images in Photoshop to playing your favorite games. The addition of the GCD likewise takes abroad the need for software developers to spend as much time managing multicore processors.

Another new technology in Snow Leopard is OpenCL, which allows software developers to tap into the power of whatsoever onboard video cards (or GPUs, for graphics processing units) for general-purpose computing without the add-on of enormous amounts of code. Like the GCD, these are improvements that will mainly touch software developers. But hopefully it will mean more than and better-performing software for users in the future.

To put some of these claims to the test, nosotros decided to pit Mac OS 10 x.five.8 Leopard confronting Mac Bone Ten ten.half dozen Snow Leopard to run across how these new technologies affected overall operation.

In our anecdotal tests of performance inside the Snowfall Leopard user interface (UI), the operating system seems faster and more than responsive than with Leopard. Finder, Stacks, Expose, launching apps, and other everyday processes feel snappy. We didn't, however, notice any improvement in application performance.

Overall, nosotros saw but a 2.5 percent slowdown in application functioning from Leopard to Snow Leopard on our more processor-intensive operation tests, including our multimedia multitasking examination, in which we measure the fourth dimension for QuickTime to stop converting a short movie while iTunes is performing its own conversion of MP3 into AAC format in the background simultaneously. As this falls within our typical margin of mistake (five percent), we saw no pregnant departure with application performance when moving from Leopard to Snow Leopard. (Encounter the bottom of this review for performance charts.)

New features

Expose
Snowfall Leopard includes a number of user UI improvements intended to make working with Mac OS X easier and more efficient. Expose, Apple'due south organization for visually finding the window yous want on a chaotic desktop, used to be relegated to the Function keys on your keyboard. Snow Leopard at present makes Expose accessible from the Dock; merely click and agree on a Dock icon to see thumbnails of all the open windows in that application. Hitting the Tab key lets you cycle through the preview thumbnails of each open application. Using Expose in the Dock is very natural and elegant, making the states wonder why this wasn't already a characteristic in Leopard.

Click and agree on an application icon in the Dock to bring upward full thumbnails of open up windows in an application.

The Dock
In addition to using Expose to find the right window, y'all now likewise have the ability to drag files from one application to some other using the Dock. Let'south say yous desire to add an image to an e-mail, simply your desktop is full of open windows. In Snow Leopard you lot tin can go to the image, drag it to the Post icon in the Dock, and your email window will spring-load, assuasive you to driblet the image into identify. Though the ability to drag and drop files in this manner is nice, nosotros're not sure it'south much easier than attaching an image by browsing through your folders. Still, if yous know the image is already on your desktop, it'south probably the faster method.

Stacks
Stacks got a much-needed upgrade too. In Leopard, Stacks simply listed a sure number of files and applications requiring you to go to a Finder window if your app wasn't listed. Similarly, if you tried to open a binder in Stacks, you were sent to the Finder. In Snow Leopard, Stacks comes with a scroll bar so icons are still easy to read and anything can be launched out of the Dock. Folders are now accessible within Stacks besides, so you'll exist able to navigate to files inside folders all without leaving the Stacks Window. These changes make Stacks much more than useful than before and probably should have been available when Stacks was introduced.

Now you tin scroll through your applications and documents (and even open folders in Stacks) without being sent to the Finder.

The Finder
While the Finder itself saw niggling in the way of interface tweaks, the way files carry in the Finder makes information technology easier to utilise. A zoom slider has been added to the lower right of Finder windows so you lot can zoom in on icons. An enhanced icon view has been added, letting y'all preview multipage documents and even play QuickTime movies without ever leaving the Finder window.

Preview now lets you preview about whatsoever file, even if it was created with software yous don't have on your hard bulldoze. This means common file types from Microsoft Excel, PowerPoint, and even PDF files can all exist previewed without owning the programs they were created in. Equally an added bonus, Preview in Snow Leopard provides accurate text selection to multicolumn PDF files using artificial intelligence to infer the layout of each page. This means that Preview recognizes that there are multiple columns in your certificate and then you can select the text you want from whatever column.

You lot can at present flip through the pages of multipage PDF documents using the arrows that appear over PDF docs when y'all mouse over.

Safari 4
Safari 4 has been widely available for some fourth dimension, merely information technology offers a couple of new features when running in Snow Leopard. Safari 4 already includes Top Sites for viewing all your favorite sites as thumbnails for easy admission and total history search, which lets you view your history in a Cover Menstruation-like interface. But in Snow Leopard, Safari is now crash resistant. This means that if a plug-in crashes, it won't crash the whole browser. Simply refresh the page to endeavour to load the plug-in again. Also, Safari checks to see if a site yous are visiting is known to be fraudulent, is distributing malware, or is known to be a phishing site, and then warns you if information technology is.

Peak Sites, which was already available in Safari 4, lets you navigate to your virtually viewed Web sites rapidly.

QuickTime 10
QuickTime 10, Apple'south media thespian, got some major tweaks in Snow Leopard. Now, when y'all play a movie and motion your mouse exterior the window, the interface fades abroad quickly to give you a more immersive video-viewing experience. When watching a motion picture, y'all can click the new Share push to convert your film for iPod, iPhone, or Apple tree Television, and QuickTime converts the video to work best on your called device. You also can now record video from your Webcam, audio, or simply the action on your screen with a few clicks. Those with the iPhone 3GS will recognize the new trimming feature in QuickTime X, letting you grab merely the video content you want.

QuickTime X probably received the well-nigh interface tweaks in the Snow Leopard update. The cleaned-up interface and autofade features look great (similar well-nigh things Apple), but information technology's more of an artful comeback than anything else. The recording features for video, audio, and screencast capturing are the big wins here and used to be offered only in QuickTime Pro. Information technology's good to see these features volition be able to be used by a wider audience in Snow Leopard.

Trim your videos easily past clicking and dragging start and stop points of the prune.

Exchange support
One of the main roadblocks for Mac users in a primarily Windows workplace was the inability to connect with Microsoft Exchange servers. Almost Mac users used Microsoft Entourage or available open-source options every bit a work-around, but information technology was never every bit polish as connecting from a Windows automobile with Microsoft Office. Snow Leopard now supports Microsoft Commutation Server 2007 out of the box so you can easily connect using Apple tree's Mail app, catch global address lists in the Address Book, and create meetings with contacts using iCal.

Apple did more than but requite you lot the ability to connect, however. Common tasks like creating meetings, for example, are incredibly easy with intuitive controls. iCal lets you lot view work events and personal activities all in the same window (with piece of cake controls to include or not include the information you want). The Apple Address Volume works seamlessly across Mail and iCal then you can apace bring up global address lists, add people to a meeting (including predesigned groups), and invitations will automatically be sent to each attendee. As an added bonus, if some attendees accept scheduling conflicts with your proposed meeting fourth dimension, iCal will automatically effigy out the primeval available time that everyone is gratuitous. These are features already available in Microsoft'southward Outlook for Windows, but in Snow Leopard the process feels much more intuitive.

File Quarantine
Co-ordinate to Apple, File Quarantine has too been refined in Snow Leopard. First introduced in Mac OS X ten.four Tiger, File Quarantine checks for known malware signatures, and in Snow Leopard, will now display an alert dialog if information technology finds a known offender. The dialog will tell users to move the offending file to the Trash. For example, a bogus version of iWork circulated on the Web a few months ago that contained malware. That detail malware is at present automatically detected by File Quarantine in Snowfall Leopard.

Apple says that File Quarantine will be automatically updated via Mac OS Ten'south software update equally new malware signatures are found in the wild. We had no mode to test these features, but we are happy to see that Apple is taking strides to defend against malware as more people switch to Macs and the danger of new malware becomes more prevalent.

Universal access
Outset with Mac OS X x.four Tiger, Apple included VoiceOver to assist people who are blind or with dumb vision to better understand and interact with what is happening onscreen. Apple continues to assistance visually impaired users in Snow Leopard past adding gesture support on multitouch trackpads with piece of cake-to-learn gestures to perform specific functions. We had mixed results with these features depending on the Web page we visited, only more often than not nosotros establish the features to be useful. The trackpad acts as the viewable area on the electric current window and then you can tap to have Window elements explained to yous or swipe to movement on to the next item in the window, for example. New features in Snow Leopard are specially helpful when Web browsing, with options like Spider web page summaries to explain the various elements on a Web folio yous haven't visited earlier, making it easier to go the data you desire.

More 40 different Braille displays (including wireless Bluetooth displays) are supported in Snowfall Leopard right out of the box, allowing visually impaired users to plug in and start calculating immediately.

Other refinements
Some of the smaller refinements in Snowfall Leopard are worthy of annotation, affecting many of Apple's core apps. iChat is now compatible with more routers, making video chat accessible to a wider range of users, and iChat Theater now offers 640x480 resolution, using only one-third the bandwidth it used before. New Chinese grapheme input via the trackpad predicts which characters you lot're creating and offers likely subsequent characters to speed up the procedure. A new text substitution feature in applications similar iChat, Mail, and TextEdit lets you create shortcuts for phrases you use frequently. The Services carte in Snow Leopard has been rewritten to include just the services relevant to the application or content you're viewing. Core Location technology locates nearby Wi-Fi hot spots to find your location and automatically resets your time zone so wherever you are in the globe, your Mac will exist set to the right time. While all of these are modest refinements, each brand your Mac easier to use with smart features not establish in other operating systems.

Conclusions
Mac OS 10 10.6 Snow Leopard is not a complete system overhaul and is instead a refinement of the electric current Leopard Os--some have gone and so far as to call it a "service pack." Nosotros think the interface tweaks to Expose, Stacks, the Finder, Mail, and iCal make Snow Leopard more than just a service pack and worthy of the $29 upgrade toll. We don't like that PowerPC users are unable to use Snow Leopard, but we understand that later on three years with Intel, Apple is making a conclusion to continue moving forrard with this applied science.

The largest of the feature enhancements are probably reason enough for Intel Mac users to spend the coin on Snowfall Leopard. Added enhancements such as video, audio, and screen recording in QuickTime X were once only available to those who purchased QuickTime Pro (which was almost $30--the same as this arrangement upgrade). Simply the killer feature addition for Snowfall Leopard might be Commutation support out of the box--not even Windows seven comes with Microsoft Exchange support without buying Microsoft Office.

Overall, we think that Snow Leopard did almost everything Apple says it set out to do: it refined and enhanced Leopard to make it easier to use. Though the system performs well in everyday use, many of our tests betoken it is slightly slower than the older version of Leopard in more intensive application processes. Withal, nosotros highly recommend upgrading for all the new features and Microsoft Exchange support.
