On this page, select “I will install the operating system later” and click Next. Guest OS Installation. Yes, you’re right, select Apple Mac OS X and OS version then hit Next. Personalize and select a preferred location for the virtual machine and click Next. Name Virtual Machine. A lot of macOS installer apps downloaded before Oct 2019/Nov 2019 contain an outdated certification chain and thus are invalid. Simply download a new OS X El Capitan install.dmg (with a valid cert chain this time), open the dmg and open the InstallOS.pkg. The installer package installs the 'Install OS X El Capitan.app' in the Applications folder.

Check compatibility If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that your Mac doesn't have enough free storage space for the installation, or that the installer is too old to be opened on this version of macOS.
Download the relevant macOS or OS X installer from Apple, then use Terminal to create a USB installer you can boot up from. Or use the OS X installation disc that came with your machine — or buy a new one — to boot up and install OS X on your Mac’s hard drive.
Doing this will allow you to install software from unsigned developers without having to confirm from within this menu. If you don't install any unsigned software within 30 days, you'll have to re-enable this settings. Click the lock icon if you'd like to prevent further changes.

In essence, High Sierra took what was good with Sierra and developed it into a more comprehensive software.

High Sierra emphasizes the already-existing benefits of MacOS previous system, Sierra. There are few bells and whistles, but the changes are noticeable and positive. The Apple file system is the most significant feature it brought. It enables the storage and encryption of a large number of files. Thus, it boosts performance and helps manage device memory issues.

Apple also introduced new formats for video and photos in this version. These formats compress data - that’s a benefit as files can get huge with ever-rising resolutions. They added support for virtual reality headsets as well.

Besides that, when it comes to Safari, Mac search engine, there are some notable improvements with the update. The users can now control annoying auto-play videos, prevent tracking, and more. There are also notification controls, and you will experience a boost in performance, too.

The most noticeable changes took place in Apple’s Photo App, though. It went through a total revamp both visually in its interface and terms of tools and functions available. Many other discreet changes happened all over the system.

Where can you run this program?

If you’re running Sierra on your Mac, you will be able to run this one as well.

Is there a better alternative?

Yes. Mojave, the newest version of MacOS, brought even more improved features to the table. However, if you can’t run it on your device, this is the second best.

Our take

High Sierra is not the shiniest upgrade Apple brought, but it’s one that sets the stage for new upgrades to come. Even out of that context, it’s a great operating system.

Should you download it?

Yes, if your device can support it. The new options and better security settings are worth getting.
