These upgrades happen once per year, normally around October, and they have a new name like Catalina, Mojave, or Big Sur.If you’re using macOS Mojave 10.14 or a newer version of macOS, you can update your Mac by clicking on System Preferences in the dock then choosing Software Update in the window that appears. Choose the macOS version you wish to restore.Apple has no official written policy on what happens when your Mac is no longer supported by major operating system upgrades. A dated list of available local snapshots and macOS versions will appear. It is usually named 'Macintosh HD' unless you changed it. If you do not have one, select the Mac's startup disk. Step 4 instructs you to select your Time Machine backup disk.
Do A System Install Firmware ThatsIMac from.MacOS is designed first and foremost for Apple’s latest computers. MacBook Pro from late 2013. MacBook Air from 2013 and later. Here are the devices that will get the new operating system: MacBook from 2015 and later. MacOS wont let you install firmware thats not developed for the model you are trying to. Its important to identify your Mac model, because thats how to correctly determine which firmware you’re on and how to install the necessary update.![]() ![]() Option 2: Install an Unsupported macOS Release AnywayApple doesn’t share why it decides to exclude a Mac from a major release, but performance likely plays a big part in the decision. If you’re determined to keep using your Mac at this stage, we’d recommend a third-party browser like Firefox, Chrome, or Edge. This might result in web pages not rendering correctly or in web apps that refuse to work. This could result in apps that you’ve purchased via the Mac App Store not updating or working at all.If you use Safari, keep in mind that your browser will stop receiving updates outside of security fixes. Some apps could require a newer version of macOS, just as iPhone and iPad apps require a minimum version of iOS. This makes it impossible to perform local backups or transfer files via a USB connection.As time goes on, you might start to lose software support, too. ![]() If you decide that an unsupported version of macOS isn’t for you, you’ll need to source the right disk image, create an install medium, and reinstall macOS from scratch to fix it.If you decide to go ahead with the installation, make sure that you make a Time Machine backup first. For instance, consider a simple task, simply minimizing a Safari window:You might also lose wireless networking, but this can likely be fixed with a few of Patched Sur’s post-install patches. This is catastrophic for performance, as documented in the Patched Sur Supported Macs document:“No graphics acceleration” is a tremendous, almost exponential, slowdown that SHOULD NOT be ignored. A note in the Patched Sur readme states: “If you have anything older than a 2012/2013 Mac, it’ll be terrible.”You might have issues with discreet GPU switching, which means that some Mac models won’t be able to use their more powerful graphics chips after the update. The main one is performance, since many models were excluded for this reason. A user-friendly release like Ubuntu will have excellent support for common bugbears like wireless adapters and trackpads, which often trip up Mac and MacBook owners. If you decide that you’d rather get more mileage out of your existing hardware regardless of which operating system you have to use, consider a desktop-ready version of Linux.For an old Mac, Linux makes the most sense. You’ll also miss out on Apple technologies like AirDrop, iMessage, and AirPlay.It’s worth taking a look at what you use your Mac for on a daily basis before taking this step. You’ll lose access to apps and services that work in tandem with your Mac, like tabs that sync between devices and seamless integration with iCloud.

You’ll need to make a bootable Windows install USB in order for this to work. There are many to choose from, including Puppy, Tiny Core, Lubuntu, LXLE, and Absolute Linux.Windows is another option, and it’s one that you can download and install without having to buy a license first. AppleEven if your Mac is no longer receiving operating system updates, it might still have a resale value on the second-hand market. In the worst-case scenario, Apple will only offer you a free recycling service. Head to the Trade in with Apple website and select your model to see how much Apple will give you for it. The latest models use ARM-based Apple Silicon systems-on-chip that use a different architecture to the Intel Macs that came before them.Read more about how Apple plans to support legacy software and new universal binaries that work across macOS, iOS, and iPadOS. Time to Upgrade?If you’re coming from a Mac that’s no longer supported, it might have been a while since you bought a Mac. If you don’t use your Mac for things like browsing the web, you won’t be exposed to some of the most common security problems. If you do this, you won’t need to worry too much about the security implications of running an outdated version of macOS. Even an outdated version of macOS is stable enough for running a media server like PLEX, hosting network files using SMB, or acting as a network Time Machine backup location.For best results, prevent your Mac from accessing the internet at all.
