macOS Big Sur support exceptions
At 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 November 12, 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.
Earlier 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.
