Make sure to be protected, do a second reboot after the update!

Apple released the macOS Big Sur update 11.3 on April 28, 2021. If Sophos is installed on an M1 (ARM) based system prior to the update, the first time the system boots after the update, protection will be compromised. Restarting the system again resolves this issue.

The issue can be observed when the following conditions are met:
1. macOS 11 had Sophos installed prior to updating to 11.3
2. Upgrading to macOS 11.3
3. M1 chip (ARM) based hardware only (Intel hardware is not impacted)
4. This also applies to the 10.1.0 M1 (ARM) Optimized EAP.

Systems that are not impacted by this:
1. Systems with Intel chip macs
2. New Sophos installs on macOS 11.3
3. Systems with macOS 10.15.7 Catalina and below

Restart the computer once again after upgrading to macOS 11.3!

Microsoft has taken a different approach to updating Windows 10, as they release major builds twice a year. Each build will have an end of lifecycle and will cease to be supported as defined by their End of Service date. Users should know that they must regularly commit to updating their Windows 10 operating system or risk cyber threat and/or block.

Microsoft has published the Windows 10 lifecycle fact sheet (, and their end of life dates ( This information is also represented in the table below.

Users should be mindful regarding Windows Updates:

  • Backup your system before doing your Windows Update, you can use Druva inSync from our software download page,

  • Run Windows Update on Windows 10, update files can be big and may take some time to download

  • Once the Update starts to download you can minimize it and continue working

  • When the download is complete it will ask for a reboot, you can pause or reschedule for the end of the day (Note: update will not finish without a reboot). Note there may be a couple of reboots involved so be patient.

  • Application of system settings after a Windows Update may require another 15-30 minutes after you reboot and login

Users can REQUEST HELP with updating their Windows 10 system.

Remember do not push off updating your computer, update regularly!


Microsoft is ending support for Windows 10 version 1909 on May 11, 2021. This applies to:

  • Windows 10 Home

  • Windows 10 Pro

  • Windows 10 Pro Education

  • Windows 10 Pro for Workstations

If you have one of the listed editions of Windows 10, it is strongly recommended and encouraged that you update it to the latest version (Windows 10 v20H2) before May 11, 2021 to continue receiving Windows updates and Security updates from Microsoft.

Please note:

  • Backup your system before doing your Windows Update. Berkeley Lab IT offers Druva inSync for backup solutions

  • Update files can be big and may take several hours to download

  • While Windows Update is downloading updates, you can minimize it and continue working

  • When the download is complete it will ask for a reboot. We suggest delaying until the end of the day, as your system will be unusable during the updates.

  • Additional updates may need to be applied after you reboot and login. It may take up to 30 minutes to apply settings before the next updates can be applied. On some rare occasions, it could be longer than 30 minutes. This process may need to be repeated multiple times until Windows is completely up to date.

Not sure how to do the update? See Run Windows Update for Windows 10.

Identity Management systems will be undergoing maintenance from 7:00 PM to approximately 9:00 PM on Thursday, March 4.

While most redundant applications are expected to continue to operate normally, there is the possibility of brief outages.

These systems include all the IT Division's authentication services, including Single Sign-On, Phonebook, RADIUS (Employee Wireless and VPN), and Multifactor Authentication services.

The Grouper group and role management application will be down for the entirety of this maintenance, along with two of its dependent services, MFA Management (the MFA token management application) and MFA Bypass.

Hold on! Before you rush to upgrade, here are the things to do:

Once you go through the list and decide to upgrade

On Thursday, February 11, 2020 at 6PM, Commons was offline for ~15 minutes while IT performed scheduled maintenance.

Any on-the-hill systems (ie having an LBL Class B or NERSC IP address) will still be allowed to relay unauthenticated via and do not need to change their outgoing/outbound SMTP settings.

This change will only be an issue for hosts that do NOT have a route to the Internet, due to either their networking configuration and/or firewall rules, or can only connect to an IP address, as opposed to a hostname.

Releasing Big Sur Upgrade

Berkeley Lab IT will be releasing the block on Big Sur for macOS. IT initiated the block to address software incompatibilities, more specifically with the Lab’s anti-virus software Sophos. Those issues can now be resolved by upgrading your Sophos client with the latest version from our Sophos server. For further information and other related postings regarding Big Sur, see:
