Mac Os Big Sur Sophos

  • MacOS Big Sur requires an astonishing 46.01 GB of storage space on your Mac – 12.18 GB just for the update file and the remaining 34.83 GB is used up to be able to deploy and perform the new.
  • MacOS Big Sur (11.0) includes additional software security on the hard drive. Additional steps are needed when installing Sophos Anti-Virus to allow access to all areas of the hard drive (for scanning, etc.). Open 'Security & Privacy' preferences. Sign on as administrator by clicking the padlock icon.

The latest operating system from Apple, macOS11 Big Sur, has arrived and it brings with it a few significant architecture modifications. In this article, we will take a look at these changes, as well as some of the things you might consider doing to automate much of the deployment of Intercept X on macOS.

macOS 11 Big Sur is now compatible with UCL's Remote Access VPN service. For more details see UCL Remote Access VPN client upgraded (now also compatible with macOS 11/Big Sur).

macOS 11 Big Sur has now moved into full release. ISD are working to prepare the Remote Access VPN service for compatibility with macOS 11 Big Sur.


However, there are two compatibility issues with the Remote Access VPN service for this new operating system:

  1. The current version of the AnyConnect client (4.8.01090) is not supported on macOS 11 Big Sur. We are working on testing the new AnyConnect client at the moment before deployment.
  2. Sophos have released a supported version of its anti-virus edition for Home users. This can however only be used on personal devices and MUST NOT be used on UCL-owned devices.
  3. Sophos do not yet have an available anti-virus edition of their Sophos Endpoint Protection which is the version that can be used on UCL-owned devices.

Therefore, based on the above reasons, it is highly recommend that you do not upgrade to MaOS 11 Big Sur in order to be able to continue successfully using the Remote Access VPN service. Further updates will be communicated here when they become available.

29 October 2020Install docker on centos 7.4.

It has been brought to our attention that Sophos Endpoint protection is not compatible with the beta/preview release of macOS 11 Big Sur.

If you choose to upgrade to macOS 11 Big Sur while it is in beta/preview, and use Sophos as your anti-virus client, you will not be able to connect to the UCL VPN service.

When macOS 11 Big Sur moves into general release, Sophos will release a supported anti-virus product.

For further information, please see Sophos's knowledge base article.

Can users with macOS 11 and the new Apple M1 hardware run Sophos Mac Endpoint Protection with the Big Sur EAP?
Yes. M1 users with Big Sur need to follow three steps:

  1. Install Rosetta 2
  2. Join the Big Sur EAP
  3. Run Sophos using Rosetta 2

What is Rosetta 2?
Rosetta 2 is a commonly used tool that enables a Mac with Apple silicon to use apps built for a Mac with an Intel processor. For instructions on installation, please refer to

Will there be a performance difference when using Rosetta 2?
Native support using the full power and performance of the Apple hardware will always be faster than using Rosetta 2. For normal business users there should not be any discernable difference. For heavy users of disk or CPU (for example: video editing, heavy photoshop usage, compiling) they will notice a difference in performance.

When is macOS 11 support coming?
The goal is to have macOS 11 support available to all customers by early March 2021. This includes support for both Sophos Central and Sophos Enterprise Console (SEC) managed devices. Brand new customers will have support from mid-February 2021. We will be upgrading all existing customers in stages, between mid-February and early March as per our normal release process.

Will Apple M1 Hardware be supported when we release Big Sur support?
Yes and this support will come in two stages. Stage 1 will be using Rosetta 2 and Stage 2 will be native support.

Sophos Central Big Sur

When will M1 processors be natively supported?
An early access program for native Apple M1 processor support will begin in early April. Planned GA is before the end of CYQ2. Native support means that Rosetta 2 is no longer required for emulation.

Mac Os Big Sur Sophos Update

Will customers need to take any action when we support macOS 11 or the Apple M1 hardware?
When we release GA support for macOS 11 we will move all EAP devices to recommended. Customers do not need to take any action. The same will be true when we GA native support for the Apple M1 hardware. All devices that were running using Rosetta 2 will automatically use the native implementation.
