Como actualizar mac os x 10.5.8 a 10.8

Like last year with the release of Mavericks, Apple chose to continue supporting all the same Macs as the previous release of the operating system. This means that if your Mac was compatible with Mavericks or even its predecessor Mountain Lion, you'll be able to upgrade to Yosemite. However, some Macs are still limited to Lion version In recent history, Apple has only patched operating system vulnerabilities for the current and two previous versions of OS X.

Still older Macs can't even be upgraded to Lion, meaning they'll be stuck with Snow Leopard version That's not a good thing, because not only does it mean there won't be any more security patches from Apple, but many third parties have already stopped releasing updates compatible with these operating systems as well. For now, the only security-related update Apple is still releasing for Snow Leopard is its XProtect "[un]Safe Downloads List," but there's no way of knowing for sure how much longer Apple will continue to update it. Meanwhile, the now three-generations-old Lion operating system is currently still getting both XProtect and iTunes updates.

However, these will likely be just about the only things Apple continues to update for Lion over the next year. Development of OS patches costs Apple money and developer resources. Although the same could be said for iTunes updates, Apple has a financial incentive to keep iTunes updated: Unfortunately, nobody knows for certain how long Apple will continue to release security patches or XProtect updates for any given operating system.

Although Microsoft publicly announces its support timetables for Windows, and the Ubuntu Linux company Canonical does likewise, Apple has never given any official word to the public regarding how long each version of Mac OS X or iOS will continue to receive security updates, and Apple consistently ignores press inquiries about when levels of support will be dropped for its operating systems. The good news is that most new Macs sold within the past several years can be upgraded to Yosemite.

Following is the list of Macs that can run a supported version of OS X. If your Mac is older than the ones listed, read on for suggestions on what you can do to upgrade to a supported system. You can do a direct upgrade from Snow Leopard v If you still have an earlier version of OS X on your compatible Mac, you will need to download Yosemite on another compatible Mac with If your Mac isn't new enough to run Yosemite, then unfortunately it's not capable of running an Apple operating system that's still fully supported.

However, if your Mac has a Core 2 Duo processor one of the models listed below , and as long as it has at least 2 GB of RAM and 7 GB of free hard drive space, it should still be able to run Lion which, although increasingly less safe to use now, is at least better than Snow Leopard or earlier because it had been getting security updates until recently:.

If Lion is the newest version of OS X that will run on your Mac, but you never purchased it while it was available in the Mac App Store, you won't be able to find it for sale there anymore. Those who are unsure which Mac model they own may find EveryMac and apple-history to be useful sites.

RAM is cheap, and you can either install it yourself by following guides available online, or simply have an Apple-authorized repair technician do it for you. Remember, even Lion isn't supported anymore, and Snow Leopard hasn't gotten new security updates for quite a while, so it's best to avoid using both of these older operating systems.

If you still use a Mac with a PowerPC processor, including G4 or G5 Macs, Apple hasn't released any security updates for your Mac's maximum operating system for over three years now. Apple hasn't sold any PowerPC-based Macs since Unfortunately, Apple doesn't give users any kind of warning when their operating system or Mac is no longer supported. Worse, when users run Apple's Software Update program, it misleadingly tells them "Your software is up to date.

This means that Mac users often have no idea that they're using unpatched, insecure software that could expose them to drive-by malware installations and other security problems. Lest you think that nobody would bother releasing malware to attack such old systems, in recent years malware has been found in the wild that was designed to attack multiple platforms, and occasionally this malware has contained PowerPC native code.

This didn't just happen once; it has happened again and again. Universal binary malware can run on old Macs, too. Image credit: While Apple boasts about the extremely high percentage of iPhone, iPad, and iPod touch devices that are rapidly upgraded to each major new version of iOS, such is not necessarily the case with Macs and OS X.

That's not terrible given that it's been out for less than a month. This makes non-upgraded Macs a potentially significant target for criminals interested in infecting large numbers of computers. Anyone still using Lion, Snow Leopard, or an earlier version of Mac OS X should strongly consider upgrading to Yosemite if their Mac supports it, or if not, they should buy new hardware if they can afford it. Let's face it, that's what Apple wants you to do anyway.

But what can you do if Yosemite is not supported on your Mac and you can't afford to buy a new computer? If you have an older Intel Mac, you have several options. While Apple may not support your Mac anymore, ironically Microsoft does; Windows 8. Oddly enough, even Windows 10 Technical Preview's system requirements hint that Windows 10 will probably run on your old Intel Mac. Microsoft's skipping the name "Windows 9," by the way. Alternatively, if you can't afford to buy a copy of Windows, or aren't interested in risking all your data to a pre-beta operating system, or just can't stand the thought of running Windows on your Mac—or if you prefer to support free and open-source software—there are guides online detailing how to install Ubuntu Linux on a Mac.

The latest versions of Ubuntu are even still being made available for PowerPC-based Macs , including those with a G3 processor. At the time of this writing, Another option is, of course, to buy a cheap PC, tablet, or Chromebook, assuming it will do all the things for which you personally need a computer. Be forewarned: The average Mac user probably won't be excited about any of those options.

I suspect that most Mac users, geeks and non-geeks alike, would rather buy a newer Mac than switch to another platform altogether. If you can't afford to buy a brand new Mac but you do have a little bit of money to spend, you can shop around for used Macs, but make sure you buy one that's new enough to support Yosemite so it will hopefully be able to get security updates for a couple more years. If you know a Mac user who's still running an older version of OS X , do them a favor and check to see whether their Mac is capable of running Yosemite.

If so, help them upgrade. If not, let them know it's time to strongly consider getting a newer computer. The burden of informing users about software and hardware that will no longer receive security updates should really fall on Apple—not on security researchers, security blogs, or blog readers. Let's hope Apple eventually figures this out and starts giving users clearer notifications when they need to upgrade lest they put their digital safety at risk. It's highly unlikely that Mac OS X v Thanks for the great, informative article Joshua.

Good luck! I am still using snow leopard Was wondering why there were plenty of spinning beach-balls on safari, and google messages of no longer supporting this browser.

That is pretty shocking, not to mention downright stupid , and thoughtless behaviour from Apple.. I use linux on a separate machine already. You can get newer versions of firefox and chrome for these old versions of OS X. Odd that they would quit supporting old hardware, though, really. Oh well, sticking with I think the article is spot on in that they keep itunes updated because they have a financial incentive to do so. And your point further exemplifies that. I have a MBP mid , I recently installed Yosemite but it does not seem to work, it would show a progress bar that does not complete and the mbp does not boot to its desktop.

What can I do? Leave it going, first boot it is doing some crazy disk check, yes it looks like the machine has crashed. Try leaving it overnight.
