News

Important!

We will continue to update this article with the latest information about macOS Big Sur (11) support in ESET products.
Latest update: 16th November 2020

macOS Big Sur 11 (formerly known as macOS 10.16) was released on 12th November 2020.

Curently released ESET security products compatible with macOS Big Sur:

  • ESET Endpoint Security for Mac 6.10.456.1
  • ESET Endpoint Antivirus for Mac 6.10.456.1
  • ESET Cyber Security 6.10.400.1
  • ESET Cyber Security Pro 6.10.400.1
  • ESET Cloud Administrator Live Installer for Mac 1.0.808.0
  • ESET Management Agent

Known issues

  • Web and Email protection does not start
    For some users Web and Email protection might not start. Your ESET product will display following error:
    System extension required for Web and Email protection was not started because of error. Try to restart macOS or reinstall the product.
    You can temporarily fix the problem by following our KB article solution, but this problem will reappear after a restart or after you shut down your computer. We are already working on fixing this issue.
Reccuring error

This issue can by now be fixed only temporarily. Because of this, we recommend you to keep your computer protected, not to upgrade your computer to macOS Big Sur.

macOS Big Sur support exceptions

In ESET we are working on Apple's mandatory change from Kernel extensions to System extensions. But due to the extensive impact that this change has on the interaction of our software with the operating system, we were not able to deliver a fully compatible product on the day of the macOS Big Sur release on 12. November 2020.

If you are using ESET products for Mac version 6.10 on macOS Big Sur, these product versions lack the following features:

  • Device control (all products)
  • Firewall (ESET Endpoint Security for macOS and ESET Cyber Security Pro)

If you are not using any of the features listed above, you are safe to upgrade your Mac to Big Sur after upgrading your ESET product.

If you are using these features, we will be releasing new versions of our products as soon as each of the missing features is ready for release. If you already installed a partially supported version of your ESET product, we recommend keeping it updated to regain the missing features right after their release.

Older macOS support

If you are not planning on upgrading your Mac to Big Sur, version 6.10 of ESET products fully support macOS 10.12 to macOS 10.15, and all features are functional.

How to keep your computer protected

To keep your computers protected by ESET, we advise you to upgrade your ESET product to version 6.10 before upgrading your computers to macOS Big Sur.

Suppose ESET products for Mac with compatible Web Access protection/Web Control and Firewall features compatible with macOS Big Sur will not be ready before the official announcement of Big Sur release. In that case, we will release new versions of ESET products with compatible Web Access protection/Web Control out of the original plan.

I already upgraded my Mac to macOS Big Sur with ESET product version 6.9 and earlier installed.

If you have upgraded your Mac to the beta version of macOS Big Sur and you have ESET product version 6.9 and earlier, your computer will not be protected, and you will receive the following message:

Unsupported macOS version
This ESET product does not support your current version of macOS 10.16.

In this case, we recommend that you upgrade your ESET product to version 6.10 and keep it updated to regain the missing features right after their release.


I am an administrator managing Macs using ESET Security Management Center (ESMC), and I already upgraded my Macs to macOS Big Sur with ESET product version 6.9 and earlier installed.

ESMC agent is supported on macOS Big Sur, and you will receive product status in ESMC. However, because ESET products for Mac version 6.9 are not supported on Big Sur, you will receive the following status:

Product is installed but it is not running

Your Macs will display the following message:

Unsupported macOS version
This ESET product does not support your current version of macOS 10.16.

In this case, we recommend that you upgrade your ESET product to version 6.10 and keep it updated to regain the missing features right after their release.
Upgrade ESET endpoint products using one-click action in ESET Security Management Center 7.


I upgraded my Mac to macOS Big Sur with ESET product version 6.10 already installed before the upgrade.

You upgraded your ESET product to version 6.10 on Mac with macOS 10.15 and older and upgraded to macOS Big Sur.

System extensions need to be allowed manually. You will receive the following warning dialogs:

For detailed instructions on how to allow system extensions visit our knowledgebase article: Allow system extensions for your ESET product for Mac.

After allowing system extensions, you will also need to allow full disc access for your ESET product to work correctly. You will receive the following warning dialog:

For detailed instructions on how to allow full disc access visit our knowledgebase article: Allow full disc access for your ESET product for Mac 6.10 and later.

After allowing system extensions and full disc access, your ESET product is functional.
