If upgrading from macOS Sierra or later, your Mac needs 35.5GB of available storage to upgrade. If upgrading from an earlier release, your Mac needs up to 44.5GB of available storage. To upgrade from OS X Mountain Lion, first upgrade to OS X El Capitan, then upgrade to macOS Big Sur. If you’re running any release from macOS 10.13 to 10.9, you can upgrade to macOS Big Sur from the App Store. If you’re running Mountain Lion 10.8, you will need to upgrade to El Capitan 10.11 first. Learn more about how to upgrade.
If you’re running an OS version like Lion (OS X 10.7), you’re looking into a lot of upgrading before getting Sierra.
To upgrade to Sierra from, say, Mavericks, you’ll have to consequently upgrade to Yosemite and then to El Capitan first.
The Steps for Upgrading to Mac OS X El 10.11 Capitan
If you’re using Leopard, upgrade to Snow Leopard to get the App Store. You can then use El Capitan to upgrade to a later macOS. OS X El Capitan won’t install on top of a later version of macOS, but you can erase your disk first or install on another disk.
This release is supported with security updates, and the previous releases—macOS 10.12 Sierra and OS X 10.11 El Capitan—were also supported. When Apple releases macOS 10.14, OS X 10.11 El Capitan will very likely no longer be supported. That’s what we can assume based on Apple’s past actions, anyway.
For the strongest security and latest features, upgrade to macOS Mojave. If you have hardware or software that isn’t compatible with Mojave, you might be able to install an earlier macOS, such as High Sierra, Sierra, or El Capitan. You can use macOS Recovery to reinstall macOS.
If you have hardware or software that isn’t compatible with macOS Sierra, you might be able to install the previous version, OS X El Capitan. macOS Sierra won’t install on top of a later version of macOS, but you can erase your disk first or install on another disk.
Many users will want to install the free update today, but some Mac owners are better off waiting a few days before installing the latest macOS Mojave update. macOS Mojave is available on Macs as old as 2012, but it’s not available to all Macs that could run macOS High Sierra.
El Capitan is the final version to be released under the name OS X; its successor, Sierra, was announced as macOS Sierra. OS X El Capitan was released to end users on September 30, 2015, as a free upgrade through the Mac App Store.
Updating a Mac to OS X 10.11.4
All University Mac users are strongly advised to upgrade from OS X Yosemite operating system to macOS Sierra (v10.12.6), as soon as possible, as Yosemite is no longer supported by Apple. The upgrade will help to ensure that Macs have the latest security, features, and remain compatible with other University systems.
If you have macOS Sierra (the current macOS version), you can upgrade straight to High Sierra without doing any other software installations. If you are running Lion (version 10.7.5), Mountain Lion, Mavericks, Yosemite, or El Capitan, you can upgrade directly from one of those versions to Sierra.
Upgrading from OS X Snow Leopard or Lion. If you’re running Snow Leopard (10.6.8) or Lion (10.7) and your Mac supports macOS Mojave, you will need to upgrade to El Capitan (10.11) first.
If you have a computer running El Capitan still I highly recommend you upgrade to a newer version if possible, or retire your computer if it cannot be upgraded. As security holes are found, Apple will no longer patch El Capitan. For most people I would suggest upgrading to macOS Mojave if your Mac supports it.
OS X “El Capitan” is named after the El Capitan mountain inside the Yosemite National Park. Apple notes that OS X El Capitan runs on the following Mac categories: iMac (Mid-2007 or newer) MacBook (Late 2008 Aluminum, Early 2009 or newer)
Even if you’re still running OS X El Capitan, you can upgrade to macOS Mojave with just a click. Here’s what you need to know! macOS Mojave is here! Apple has made it easier than ever to update to the latest operating system, even if you are running an older operating system on your Mac.

|macOS High Sierra Download||20 minutes to an 1 hour|

El Capitan was born of fire. The 3,000-foot-tall, 1.5-mile-wide granite cliff that rises up from the present-day Yosemite Valley in central California started forming roughly 220 million years ago, when ancestral North America collided with a neighboring tectonic plate under the Pacific Ocean.

The first, and most important thing you should do before upgrading to macOS Mojave (or updating any software, no matter how small), is to back up your Mac. Next, it is not a bad idea to think about partitioning your Mac so you can install macOS Mojave in tandem with your current Mac operating system.
