Since macOS Sierra, which appeared in 2016, macOS displays a button that can activate Siri in the upper right corner of the screen, allowing you to perform various operations with just your voice, just like on iPhones and iPads. However, depending on the settings, Siri always collects surrounding sounds to start with the voice command 'Hey Siri', and data when using Siri may be sent to Apple. Apple explains that ``Siri data is encrypted and sent to Apple after it cannot be associated with an individual,'' but as long as Siri's source code is not disclosed, data transmission is safe. Some users are worried about security and privacy because it is impossible for a third party to evaluate their sexuality.

Script 'Kill Siri' to completely disable Siri
After running all the above commands, Siri related processes such as 'com.apple.siri.embeddedspeech', 'siriactionsd' and 'sirittsd' still continue to work. According to term7, some of Siri's services are protected by macOS ' System Integrity Protection (SIP) ' and cannot be disabled by normal means. You can disable Siri completely by disabling SIP , but disabling SIP is not recommended as it increases the risk of attack on your system.
