Having worked at NASA and the NSA, as well as presented at countless security conferences, he is intimately familiar with aliens, spies, and talking nerdy. Patrick is passionate about all things related to macOS security and thus spends his days finding Apple 0days, analyzing macOS malware and writing free open-source security tools to protect Mac users.
也许开源更加安全，也许未必，但免费是实打实的。

@Pin 我在家用 little snitch ，在公司用 lulu 。感觉 lulu 的 rules 和 monitor 界面比 little snitch 差不少。

开启 private relay 以后，非 https 链接都套一个 icloud.com 的地址，最初目的是为了安全，但所有防火墙都会默认放行。这有很大问题，相当于此时防火墙失效了。
