BIG SUR EAP: Known Issues List

Please create a new post in the Discussions section for any questions or comments.

This is a list of Known Issues with the EAP version of the software:

• System requires a reboot after installation:
  • After adding scan extension to full disk access, a reboot is required
  • [Fixed in: 10.0.3] Network extension requires reboot in order to accept inbound network connections
• Users must allow network extension to add proxy configurations in order for network interception features to function.
• [Fixed in: 10.0.3] Network extension will experience memory growth while handling non-browser traffic
• CryptoGuard and scan extension may experience periods of high CPU consumption under heavy load
• CryptoGuard may be unable to exclude applications that run from the user's Desktop
• Sophos Central will display “macOS” instead of “macOS Big Sur 11.0”
• System Extensions might remain after uninstall
  • see this for instructions on how to remove:

• Endpoints that update through an Update Cache will not be able to update to/install the EAP version

• [Fixed in: 10.0.3] Time Machine backups to network locations fail with message "Time Machine couldn't complete the backup - The disk is already in use"
  • As a workaround, run the backup in Safe Mode
• [Fixed in: Big Sur 11.2] There is an incompatibility between two APPLE APIs in Big Sur: NEFilterDataProvider and NETransparentProxyProvider
  • Any products that use one API will interfere with products using the other
    • This causes problems with websockets implemented with CFStream or NSStream
  • Our network extension uses NETransparentProxyProvider
    
    • Until Apple provides a fix to the API - websockets may not function properly if there are two or more products that use these APIs
• After upgrade to 10.0.3, users might be required to authorize the updated System Extensions (Scan and Network)
