Versiones de mac os x tiger

After the code name "Jaguar" for version 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. Simply releasing Mac OS X was received by the Macintosh community as a great accomplishment, for attempts to completely overhaul the Mac OS had been underway since , and delayed by countless setbacks.

Following some bug fixes, kernel panics became much less frequent. Mac OS X Apple released On January 7, , Apple announced that Mac OS X was to be the default operating system for all Macintosh products by the end of that month. In addition to providing much improved performance, it also incorporated the most extensive update yet to the user interface.

Apple stated that Tiger contained more than new features. The initial release of the Apple TV used a modified version of Tiger with a different graphical interface and fewer applications and services. On January 10, , Apple released the first Intel-based Macs along with the This operating system functioned identically on the PowerPC-based Macs and the new Intel-based machines, with the exception of the Intel release dropping support for the Classic environment. The single DVD works for all supported Macs including bit machines.

New features include a new look, an updated Finder, Time Machine , Spaces , Boot Camp pre-installed, [24] full support for bit applications including graphical applications , new features in Mail and iChat , and a number of new security features. Rather than delivering big changes to the appearance and end user functionality like the previous releases of Mac OS X , the development of Snow Leopard was deliberately focused on "under the hood" changes, increasing the performance, efficiency, and stability of the operating system.

For most users, the most noticeable changes are these: the disk space that the operating system frees up after a clean installation compared to Mac OS X 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.

It dropped support for bit Intel processors and requires 2GB of memory. Documents auto-save by default. It incorporates some features seen in iOS 5, which 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. 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. Notes is added, as an application separate from Mail, synching with its iOS counterpart [32] [33] through the iCloud service. Messages, an instant messaging software application , [34] replaces iChat.

Mavericks requires 2GB of memory to operate.

It is the first version named under Apple's then-new theme of places in California , dubbed Mavericks after the surfing location. It featured a major overhaul of user interface, replaced skeuomorphism with flat graphic design and blurred translucency effects, following the aesthetic introduced with iOS 7. It introduced features called Continuity and Handoff, which allow for tighter integration between paired OS X and iOS devices: the user can handle phone calls or text messages on either their Mac or their iPhone, and edit the same Pages document on either their Mac or their iPad.

Apple described this release as containing "Refinements to the Mac Experience" and "Improvements to System Performance" rather than new features. Refinements include public transport built into the Maps application, GUI improvements to the Notes application, as well as adopting San Francisco as the system font.

As noted previously in the Snow Leopard section, a couple months after Mountain Lion's initial release, Apple upgraded XProtect's functionality to start blocking outdated versions of the Flash Player and Java plug-ins, and this feature was retrofitted into Lion and Snow Leopard's versions of XProtect as well.

In OS X This is essentially Apple's answer to the growing popularity of password managers; Apple would prefer to handle this for you and, of course, keep you locked into the Apple ecosystem by doing so. Apple does use industry-standard security measures to protect iCloud Keychain data, but the paranoid among us tend to be at least a bit concerned about so many users' passwords being stored in one place in the cloud; it makes Apple's iCloud servers a potentially huge target for determined groups of attackers with vast resources.

Yosemite introduced a new feature of Apple Mail called Mail Drop , which allowed users to send "attachments" of up to five gigabytes without actually attaching a file to the e-mail.

Mac OS X 10.4

A security and privacy advantage of Mail Drop is that attachments expire thirty days from when the e-mail is sent; after that they can no longer be downloaded. Thus if the recipient's e-mail account gets compromised at some point more than thirty days in the future, an attacker won't be able to retrieve past "attachments" you sent them, whereas with traditional attachments they would be able to retrieve them. Unfortunately, Mail Drop is currently limited to what Apple deems attachments "too large to send in email," so not everyone can take advantage of this feature for any attachment.

The version of Safari included with Yosemite defaulted to showing only the domain in the address bar, rather than the entire URL. Some argued that this increased security for the average user, because it prevented attackers from hiding behind convoluted URLs such as paypal. Users can still see the full URL by clicking in the address bar. Another change to Yosemite's Safari was that, for the first time, Apple introduced per-window Private Browsing, making the feature a bit more convenient. Apple introduced the Swift programming language alongside Yosemite, which has a number of security advantages.

Although Apple does not force developers to use Swift at least not yet , Apple has given developers an easier way to write software that is inherently more secure. The most important new security feature in OS X This can prevent a user from accidentally damaging the OS, and it's also designed to help prevent malware from injecting itself at a deeper level PDF where it can be more difficult to remove.

System Integrity Protection is enabled by default, but Apple currently allows users to disable it after booting to the Recovery partition. Apps created for El Capitan and iOS 9 have this feature enabled by default, but for now Apple allows developers to easily opt out and continue making connections using weaker encryption e. Additionally, Apple updated XProtect in January to block vulnerable versions of Microsoft's Silverlight browser plug-in which Microsoft is gradually phasing out.

This XProtect update was retroactive all the way back to Snow Leopard. Each new version of OS X released over the past decade has included additional features, enhancements, and modifications that have improved the baseline security of the operating system. It is commendable that Apple continues to make efforts to increase OS X's security in new ways with each release.

Of course, as is expected of major software companies, Apple also releases security updates to remediate vulnerabilities discovered in the current and often one or two previous versions of the OS. Do all of these security features actually help make Macs more secure? As mentioned to some degree above, many security enhancements can be worked around by a determined attacker for further reading, see our previous article on the topic. Even with all that Apple has done and continues to do to keep Mac users safe, it's critical for users to stay aware of the various types of attacks they may face on a daily basis, and to continually learn how to avoid falling victim to them.
