mac上你从网页、QQ或微信等下载一个sh脚本,不要忙焦急着去执行,要不然会报上面的谬误
sudo: unable to execute ./sh/ijiami-clang-install.sh: Operation not permitted遇到这个问题该咋办,别着急咱们来分析一下是为什么起因,ls -l一下
失去上面列表,都有执行权限,等等前面为啥有个@,百度可知这是个暗藏属性.

macOS Catalina 退出了一项名为 GateKeeper 的爱护机制，从互联网上下载来的文件，会被零碎打上 com.apple.quarantine 标记，也就是免疫隔离，本意是为了防止利用威逼，从而增强零碎安全性。
坑爹啊只能把这个暗藏属性给干掉啊
sudo xattr -r -d com.apple.quarantine +目录门路
