[macOS] macOS 15 Beta 8 防火墙有问题

发表于

之前用的 mac 14.6.1 ，昨天升级到 15 Beta 8 ，升级后浏览网页没问题，在终端里 ping 不了任何域名和 ip 。

PING 114.114.114.114 (114.114.114.114): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1

怀疑是防火墙的问题，关闭后一切正常。也就是说防火墙屏蔽了 icmp 包。 之前在 14.6.1 的防火墙设置是 block all incoming connections 。但是 15 Beta 8 下，不论是否开启这个选项均无法解决该问题，必须关闭防火墙才行。

想问问大家这是个例还是普遍情况？ 谢谢！
