安装完成Charles之后提示
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：
sudo chown -R root "/Applications/Charles.app/Contents/Resources"
sudo chmod -R u+s "/Applications/Charles.app/Contents/Resources"
之后重新进入
