最近刚升级了 mac，在使用 homebrew 的时候会提醒：

Warning: You are using macOS 11.0.
We do not provide support for this released but not yet supported version.
You will encounter build failures with some formulae.
Please create pull requests instead of asking for help on Homebrew's GitHub,
Discourse, Twitter or any other official channels. You are responsible for
resolving any issues you experience while you are running this
released but not yet supported version.

尝试安装某个命令行工具的时候会报错：

Error: Your CLT does not support macOS 11.0.
It is either outdated or was modified.
Please update your CLT or delete it if no updates are available.
Error: An exception occurred within a child process:
SystemExit: exit

在社区的搜索结果：

https://discourse.brew.sh/t/macos-big-sur-issue/8407 同上

https://github.com/Homebrew/brew/issues/7857 说由于 CI 环境缺失最近几个不会支持 arm 下的 homebrew

p.s.: 机器是 Intel CPU.
