Download mountain lion unsupported mac

Those who are unsure which Mac model they own may find EveryMac and apple-history to be useful sites. If you have a compatible Mac with a version of OS X that predates Lion for example, Snow Leopard , you will need to download Sierra on another compatible Mac with Lion or later, create a bootable Sierra flash drive or external hard drive using Apple's official instructions or the third-party tool DiskMaker X , and do a clean install overwriting the hard drive on your Mac—so be sure to carefully back up all of your files first.

An alternative solution for upgrading a compatible Mac from Snow Leopard to Sierra is to first upgrade to your choice of Lion through El Capitan if you happen to have a bootable installer from one of those versions of macOS handy, or if you're able to download one from the Purchased section of the App Store and use DiskMaker X to create a bootable installer , and then do a second upgrade from that macOS version to Sierra. Taking this upgrade path will allow you to preserve your hard drive's contents.

Mountain Lion

If your Mac can't run Sierra, there's still a decent chance that it can run the previous version of macOS, El Capitan, which may continue to receive security updates from Apple for another year or two. If your Mac is currently running Mountain Lion, Mavericks, or Yosemite, then it definitely meets the minimum system requirements for running El Capitan and it might even be Sierra-capable; refer to the previous section.

How to Upgrade Unsupported Mac to macOS Mojave

If your Mac isn't new enough to run Sierra or even El Capitan, then, unfortunately, it will no longer receive much support from Apple. Sadly, Apple doesn't give users any direct warning when their operating system or Mac is no longer supported. Worse, when users check the App Store for updates or on older Macs when users run Software Update , it misleadingly tells them, "No Updates Available" or "Your software is up to date. This didn't just happen once ; it has happened again and again. Universal binary malware can run on old Macs, too. Image credit: Kaspersky. 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.

Based on the newly released Net Applications data for November , it appears that Sierra has been installed on nearly one third of the Macs that were used for Web browsing last month. Meanwhile, El Capitan, which has been out for over a year and is still being supported, is currently tied with Sierra at one third of the Mac market share, and Yosemite is in third place at just over one-fifth of the active installed base. All older versions of OS X, though, together comprise more than In other words, about 1 in every 7 Macs in use today is no longer getting security updates.

This makes non-upgraded or non-upgradeable Macs a potentially significant target roughly 20 to 30 million computers for criminals interested in infecting a large quantity of devices. Anyone still using a Mac that cannot be upgraded to Sierra, or at least El Capitan, should strongly consider buying new hardware if they can afford it. If you have an older Intel Mac, you have several options. One solution is to set up Boot Camp and install Windows to use as your Mac's primary operating system. At the time of this writing, 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.

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 macOS Sierra. If so, help them upgrade. If not, let them know it's time to strongly consider getting a newer computer.

Of course, informing users about software and hardware that will no longer receive security updates should be primarily Apple's responsibility—not merely that of security researchers, security blogs, or blog readers. Let's hope that Apple eventually figures this out and starts giving users advanced warning and clearer notifications when they need to upgrade lest they put their digital safety at risk.

As an aside, 1 in 7 Macs is a slight percentage decrease as compared with January when I last brought this up ; at that time 1 in 5 Macs were no longer getting security updates. The decreased percentage of unpatched or unpatchable Macs since then is likely due in part to fewer old Macs still being in use almost two years later, and many new Macs being sold in the mean time. Wow, Kudos to you Joshua for a long and informative piece. This kind of useful information is so rare these days online….

There is a lovely free installer that helps. This even explains a special update feature that allows you to continue using the Sierra updater without fear.

What to Do if Your Mac Can’t Run macOS Sierra

You can install windows 10 latest on computers all way back to Any ideas which of all these options is the most effective or easy to implement for a relative newbie? Or which combination of them? While these details have prevented Apple from officially supporting these systems, for those who own them there is a ray of light that may allow them to run Mountain Lion, if they so choose.

A new procedure outlined at Jabbawok's blog derived from a procedure outlined at netkas. Upgrading the graphics card is fairly simple and can be done using the Apple-supplied and supported Radeon HD kit that is available from the Apple Store. Unfortunately the simplicity of this process ends there; it requires you use a secondary internal drive as an intermediary for modifying the OS X boot loader and copying specific system files in order to allow the Mountain Lion installer and OS to run.

Summary: install Mountain Lion on unsupported Mac - working as of | MacRumors Forums

In addition to the complexity of the procedure, it is not guaranteed to work, and since the final setup will not be a supported configuration by Apple, it may result in a less stable system. Because of this, the Jabbawok procedure should more appropriately be recommended as a hobby for curious users rather than a concrete solution for those needing to install Mountain Lion on their early Mac Pros.

A final note is that this procedure will only work on the Mac Pro systems. Other unsupported Macs like iMacs, Mac Minis, and MacBook systems have graphics cards that cannot be upgraded; therefore even if the emulated firmware is installed, on these systems Mountain Lion will likely hang or crash when loading or performing certain tasks.
