默认是安装不上的，因为brew 不维护老系统了

Run brew edit openssl@3 or find the file openssl@3.rb and edit it.
Look for the line system "make", "test"
Change it to system "make", "test TESTS='-test-cmp_http'" and save the file
Run brew install --build-from-source --formula /path/to/openssl@3.rb. Make sure you change the path to wherever your file is. In my case it was in /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/o/openssl@3.rb.
