Adguard can make your online experience safer because, though Macs and Apple laptops are quite safe to use, when it comes to ad blockers, Macs experience real problems. Already-existing solutions do not consider the specifics of macOS. That greatly influences the stability of work in Safari, and these ad-blocking extensions fail to do their work properly, especially when video ads are an issue.
*** You need to disable the System Integrity Protection (SIP) to perform the selected Application. !!!!!! For Safari you need to use the old Adguard Assistant in the program settings
