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.
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.
