抓包工具Charles-代理-macOS-Proxy,报错如下：
Charles cannot configure your proxy settings while it is on a read-only volume. Perhaps you are running Charles from the disk image? If so, please copy Charles to the Applications folder and run it again. Otherwise please ensure that Charles is running on a volume that is read-write and try again.
解决办法：
在Mac终端中输入：sudo chown -R root "/Applications/Charles.app/Contents/Resources"
接着输入密码；回车，重启Charles就可以了。
