Here's how to check which release of the macOS operating system is installed on your MacBook, iMac, Mac Mini, or Mac Pro.
To find this information, click the Apple icon on the menu at the top left corner of your screen, and then select the 'About This Mac' command.
First, click on the Apple icon in the top left corner of your screen. From there, you can click ‘About this Mac'. You'll now see a window in the middle of your screen with information about the Mac you're using. As you can see, our Mac is running OS X Yosemite, which is version 10.10.3.
Left to right: Cheetah/Puma (1), Jaguar (2), Panther (3), Tiger (4), Leopard (5), Snow Leopard (6), Lion (7), Mountain Lion (8), Mavericks (9), Yosemite (10), El Capitan (11), Sierra (12), High Sierra (13), and Mojave (14).

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.
For example, in May 2018, the latest release of macOS was macOS 10.13 High Sierra. 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.
Apple unveiled the newest version of the Mac operating system at 2018 Worldwide Developers Conference (WWDC) last June, but finally released it to the public in September. MacOS Mojave is a free update to Mac users, and it's a pretty big upgrade.
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. Click here for instructions.
The first thing to do is check to see if your Mac can run macOS High Sierra. This year's version of the operating system offers compatibility with all Macs that can run macOS Sierra. Mac mini (Mid 2010 or newer) iMac (Late 2009 or newer)
Some examples include versions of Microsoft Windows (like Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP), Apple's macOS (formerly OS X), Chrome OS, BlackBerry Tablet OS, and flavors of the open source operating system Linux.

Apple's macOS High Sierra update is free to all users and there is no expiration on the free upgrade, so you don't need to be in a rush to install it. Verbatim hard drive mac. Most apps and services will work on macOS Sierra for at least another year. While some are already updated for macOS High Sierra, others are still not quite ready.
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)
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.
I've been using Mac Software since Mac OS X Snow Leopard 10.6.8 and that OS X alone beats Windows for me.
And if I had to make a list, it would be this:
The full support list is as follows:
macOS High Sierra is compatible with any Mac that's capable of running macOS Sierra, as Apple hasn't changed the system requirements this year. Here is the official list of supported hardware: MacBook – Late 2009 or later. Mac mini – 2010 or later.
All Mac Pros from late 2013 and later (that's the trashcan Mac Pro) will run Mojave, but earlier models, from mid 2010 and mid 2012, will also run Mojave if they have a Metal capable graphics card. If you're not sure of the vintage of your Mac, go to the Apple menu, and choose About This Mac.
