MacOS更新到12.1后引发的kubectl报错atal error: runtime: bsdthread_register error问题排查

两年前入手的Macbook Pro，一直没有更新系统，突然就想着更新一下，直接更新到最新的macOSMonterey 12.1，没想到更新后问题就来了。k8s命令kubectl直接就报错了，报错如下：

kubectl get po -n wgms-dev -o wide

fatal error: runtime: bsdthread_register error

runtime stack:

runtime.throw(0x2cb65a5, 0x21)

/usr/local/go/src/runtime/panic.go:596 +0x95 fp=0x7ff7bfeff500 sp=0x7ff7bfeff4e0

runtime.goenvs()

于是进行了各种尝试，最总确定需要重新安装kubectl，首先卸载了已经安装的kubectl,具体操作参考：https://blog.csdn.net/zhaoyangjian724/article/details/111150283?utm_medium=distribute.pc_aggpage_search_result.none-task-blog-2~aggregatepage~first_rank_ecpm_v1~rank_v31_ecpm-2-111150283.pc_agg_new_rank&utm_term=%E5%8D%B8%E8%BD%BDkubectl&spm=1000.2123.3001.4430

然后重新安装kubectl,接下来问题来了，如下安装直接报错 ：Warning: Failed to create the file kubectl: Read-only file system

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/darwin/amd64/kubectl" 

于是开始排查，Mac出现Read-only file system，有可能是系统更新到最新版本后，无法向根节点写入，解决版本有两个

1：关闭系统的sip 具体方法参考：https://zhuanlan.zhihu.com/p/80246665
按步骤关闭后发现并没有用
2：建立根目录软连接，具体参考：https://newsn.net/say/mac-big-sur-root-readonly.html
软件连接建立后，进入/Users/你的用户/data目录下执行安装kubectl后成功，安装教程参考：https://kubernetes.io/zh/docs/tasks/tools/install-kubectl-macos/
