Avast mac security multithreaded7/12/2023 Please note that this issue is not unique to Avast this is unavoidable if MacOS decides to not pass the connection through Private Relay. Unfortunately, the mere fact that Network Extension is configured to be notified about HTTP(S) connections causes Private Relay to be disabled even for those it does not actually process.Īpple Mail detects that the connection did not go through Private Relay, and displays the following line on the top of the mail: “Your network preferences prevent content from loading privately.” and a button "Load Content Directly". Avast's Web Shield component is registered in Network Extension to be notified about all HTTP(S) connections for web browsers, it processes such connections transparently for other connections (including those from Apple Mail) it tells Network Extension: "I am not interested, pass the connection through". What is going on: In case a mail contains HTML mail body, Apple's Mail app uses HTTP(S) to load various elements (like pictures). Unfortunately, Apple has decided to not use this functionality in their Monterey implementation of Private Relay functionality and to make it mutually exclusive with Network Extension based extensions - a very unfriendly and anti-competitive thing to do. The Network Extension framework allows multiple vendors to add their own security and privacy specific filters to the same connections on the same machine, thus allowing coexistence and cooperation of such 3rd party products. In MacOS Big Sur, Apple has discontinued kernel extensions for implementing network filters, like Avast Web Shield or Avast Mail Shield instead a new mechanism (Network Extension framework of System Extension functionality) was added. Or you have to click on "Load Content Directly" on the top of the email for every email. ![]() The workaround is to go to Mail -> Preferences -> Privacy and disable both "Protect Mail Activity" and "Hide IP Address". ![]() It seems that the issue is caused by the unfortunate way how iCloud Private Relay feature Apple has added to MacOS Monterey is implemented.
