Is High Sierra Still Supported? NO.

From the table, you can see that Apple no longer supports High Sierra. It means Apple has stopped providing security support and updates for this operating system.

On the first of December 2020, Apple ended up serving security support and updates for macOS 10.13 High Sierra. SCSCF has stopped providing software support for all computers using macOS 10.13 High Sierra.

Are you feeling backdated? You should be.

The following version of macOS High Sierra is macOS 10.14 Mojave. Even Mojave is no longer receiving any software updates. On 25 October 2024, Apple ended up providing security updates for Mojave.

Risks Of Having High Sierra


As it is outdated, it is surely at risk. Having backdated drivers can cause trouble to your computer. Here, having the whole operating system outdated can create more problems.

Your computer is vulnerable to viruses and malware as it no longer gets security updates. As a result, you are putting all your data at risk.

So, when you are online, you are prone to get attacked by viruses. Even the campus-recommended antivirus for Macs now doesn’t have any security support.

However, the straight point is outdated operating system is not protected from malicious attacks. And you are at risk of losing your important data.

What Do The Users Say?


The users’ review about still running High Sierra is quite hopeful. The primary fact is that if you are careful about what you do when you are online, you are safe.

I roamed around different forums and community sites to collect reviews of High Sierra users. Most users, from Apple Support to Quora and Reddit, emphasize your online activities.

According to most users, you can still safely use High Sierra if you are careful about the dark corners on the internet. Using a good browser and antivirus will save you from virus attacks.


All the reviews were not so good about still using High Sierra. After all, you are not getting any official security support. Also, you won’t be able to use many updated software and applications.

The Advantages You Are Missing By Using High Sierra

How to Upgrade Old MacBook

Apart from the risk of virus attacks, you also miss some advantages. With the new version of macOS, Apple provides new updates on pretty much everything.

Also, many third-party software will not be supported on your computer if you still have High Sierra. Let’s see what you are missing by running High Sierra.

Privacy Protection
  • Setting up apps for the first time is not safe
  • Few apps cause trouble even after the security & privacy pane
  • Knows nothing about notarization
  • Only have the gatekeeper check
File System
  • High Sierra has no support for the firm links
  • The data backup system is too backdated and weak
Apps & Software
  • Software gets unsupported
  • Adobe & Microsoft tend to support only current released

If you look at the updated versions of macOS, you will want to update your macOS. Compare High sierra with Catalina, Big Sur, and Monterey. You will understand why I am calling you old.

Every update comes with new technology, more privacy protection, more security, an advanced file system, and more compatibility.

Upgrade High Sierra To Current macOS

You have already seen why you should not run High Sierra. Let me give you some reasons why you should upgrade your macOS.

No Security Fixing For High Sierra

In the meantime, a severe security flaw was seen in macOS. Apple fixed the problem for Big Sur, Catalina, and Mojave. But they did not fix it for High Sierra.

Many Software vendors are also following the path of Apple. For example, Microsoft announced that High Sierra would not get any future updates for Microsoft Office 365.

Furthermore, Apple announced that starting with macOS Catalina, 32-bit apps will not be compatible with macOS. They are transitioning to 64-bit technology.

So, if you do not upgrade your macOS, you will lose compatibility with using the macOS.

Who Can Not Upgrade High Sierra?

update Catalina

If you want to upgrade High Sierra to any current macOS, it is possible. But your computer or mac must have compatibility for the upgrade.

Apple would consider it vintage if your mac was released five to seven years ago. If they are older than seven years, Apple considers them obsolete.

Here is a list of computers that can not run Mojave or higher macOS.

Many of us still can not leave our love for High Sierra. High Sierra still gives its best for some old computer models.

So, if you want to stay old-fashioned, it is completely okay. But you have to be cautious about virus attacks. Follow my instruction to save your mac computers.

Careful About The Sites You Visit

You have to be very selective and aware of online roaming. You could be easily a victim of trojan, phishing, and other scams.

Read this article from Boston University on How to Identify and Protect Yourself from an Unsafe Website. It is really helpful.

Careful With Emails You Receive

How to use Mail on your Mac

Do not open an email without being 100% sure it is legit. Scammers are getting skilled day by day. So, you will be confused by the appearance of the emails they send.

Even if you accidentally open a suspicious email, do not click on any links or attachments with it. Send them to the trash immediately.

Use A Secured Browser

Mozilla Firefox is my suggestion. It works excellent with older versions of macOS. Also, using this browser will serve you front-line protection.

Though you won’t be able to update your macOS, you can still update the browser. Adding Privacy Badger, uBlock Origin, and HTTPS Everywhere will provide extra security.
