With the rise of ransomware and other malicious software, some macOS users wonder if they should block all incoming computer connections. This is a valid question, but there is no easy answer. There are a few things to consider when deciding whether or not to block all incoming connections on your Mac. The first is what you use your computer for. If you only use it for basic tasks like browsing the web and checking email, blocking all incoming connections may be overkill. If you use your computer for more sensitive activities like online banking or shopping, you may want to consider blocking all incoming connections. This will help protect you from malware and other attacks that can harm your computer or steal your information. Another thing to consider is how much work you would have to do to set up and maintain a firewall on your Mac.
