之前安装过一次，没问题，这次按照之前教程装了就不管上传下载都会卡住；

step1: 

brew install lrzsz

step2：在/usr/local/bin  路径下配置两个sh,之前从网上找到的直接用都不对，下面这个是调试过的正式可用的

iterm2-recv-zmodem.sh

if [[ $FILE = "" ]]; then
	echo Cancelled.
	# Send ZModem cancel
	echo -e \\x18\\x18\\x18\\x18\\x18
	sleep 1
	echo
	echo \# Cancelled transfer
else
	cd "$FILE"
	/usr/local/bin/rz -E -e -b
	sleep 1
	echo
	echo
	echo \# Sent \-\> $FILE
fi

step3: 建立软连接

sudo ln -s /opt/homebrew/bin/sz /usr/local/bin/sz
sudo ln -s /opt/homebrew/bin/rz /usr/local/bin/rz
