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.
If your computer does not meet the minimum requirements for Catalina or Mojave, you will not be able to install a supported version of macOS. If this is the case, you will need to replace your current computer with a newer model.
If you are on macOS Mojave or an older version of macOS 10.15, you should install this update to get the latest security fixes and new features that come with macOS. These include security updates that help keep your data safe and updates that patch bugs and other macOS Catalina problems.
Support Ending November 30, 2021In keeping with Apple's release cycle, we anticipate, macOS 10.14 Mojave will no longer receive security updates starting in November 2021. As a result, we are phasing out software support for all computers running macOS 10.14 Mojave and will end support on November 30, 2021.
If you have a fusion drive, then Mojave is almost certainly the better bet for you. If you're an iPhone or iPad user, then you may want to consider Mojave for the increased compatibility with iOS. If you plan to run a lot of older programs that don't have 64-bit versions, then High Sierra is probably the right choice.
Mac Hardware RequirementsThese Mac models are compatible with macOS Mojave: MacBook (Early 2015 or newer)MacBook Air (Mid 2012 or newer) Mac Pro (Late 2013; Mid 2010 and Mid 2012 models with recommended Metal-capable graphics cards)
El Capitan was replaced by Sierra 10.12, High Sierra 10.13 and the current release, macOS 10.14 Mojave. As a result SCS Computing Facilities (SCSCF) is phasing out software support for all computers running macOS 10.11 El Capitan and will end support on October 31, 2019.
Apple said that would run happily on a late 2009 or later MacBook or iMac, or a 2010 or later MacBook Air, MacBook Pro, Mac mini or Mac Pro. If you Mac is supported read: How to update to Big Sur. This means that if your Mac is older than 2012 it won't officially be able to run Catalina or Mojave.
macOS Mojave (/moʊˈhÉ‘Ëvi, mÉ™-/ mo-HAH-vee; version 10.14) is the fifteenth major release of macOS, Apple Inc.'s desktop operating system for Macintosh computers. Mojave was announced at Apple's Worldwide Developers Conference on June 4, 2018, and was released to the public on September 24, 2018.

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.
macOS Sierra had introduced Share Desktops, while Mojave introduces Desktop Stacks. Mojave groups files, folders, and photos you drag onto your desktop. You'll no longer need to hunt for a particular document. Instead, you can click on the relevant stack to see a list of files of that type.
Why is Big Sur slowing down my Mac? Chances are if your computer has slowed down after downloading Big Sur, then you are probably running low on memory (RAM) and available storage. Big Sur requires big storage space from your computer because of the many changes that come with it. Many apps will become universal.
In keeping with Apple's release cycle, Apple will stop releasing new security updates for macOS High Sierra 10.13 following its full release of macOS Big Sur. As a result, we are now phasing out software support for all Mac computers running macOS 10.13 High Sierra and will end support on December 1, 2020.
The macOS big sur takes 30 to 45 minutes generally to install. The big sur update is about 12 gigs. For a few users, it takes just 20 minutes for the complete installation. If users are moving from mac os Catalina, then their installation could take around 20 minutes.
As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.
Which macOS version is the latest?
| macOS | Latest version |
|---|
| macOS Big Sur | 11.6 |
| macOS Catalina | 10.15.7 |
| macOS Mojave | 10.14.6 |
| macOS High Sierra | 10.13.6 |
In that case, you may be looking to downgrade to an older version of macOS, like macOS Catalina or macOS Mojave. The easiest way to downgrade from macOS Big Sur is by formatting your Mac and then restoring it from a Time Machine backup that was made prior to the installation of macOS Big Sur.
Apart from the design change, the latest macOS is embracing more iOS apps via Catalyst. What's more, Macs with Apple silicon chips will be able to run iOS apps natively on Big Sur. This means one thing: In the battle of Big Sur vs Catalina, the former certainly wins if you want to see more iOS apps on Mac.
To get updates for Mojave or Catalina without upgrading to Big Sur, go to the Apple menu > System Preferences > Software Update. Ignore the offer to upgrade to macOS Big Sur and look a little lower to the section that says “Another update is available†and click “More info†below that.
Supported Versions of macOSApple is only supporting macOS 10.11 or later. Apple stopped providing security updates for macOS 10.8 and earlier versions with the release of macOS 10.11 (El Capitan) in 2015.
The iPhone 5c stopped being supported last year with iOS 11, and the iPhone 4s has not been supported since 2015 with the release of iOS 10. The iPad Air is still supported, and the iPad 2 stopped receiving updates in 2016 with iOS 9.3. 5 being the last one.
Apple unveiled macOS 10.14 Mojave back in June 2018 at the WWDC 2018 event, and during that time, many of its features were showcased. This announcement was then followed by a public beta launch in July 2018. Finally, a full launch of the operating system happened on September 24, 2018.
