# 1.先在真机安装抓包软件:Wireshark
# 2.在虚拟机Mac里因为走的是NAT网卡，于是监听该网卡
# 3.正常通过App Store 安装、更新 APP
# 4.在 Wireshark 里过滤 HTTP 协议
# 5.找到 *.pkg *.pfpkg实际下载地址，然后通过下载软件下载好
# 6.然后通过以下命令听过Host改走本地Http即可

sudo python -m SimpleHTTPServer 80

#edit your mac‘s /etc/hosts file to add following line

# open "App Store" app on Mac. And run update.
# It should download pkg file from local/LAN server

#Important - remove /etc/hosts entry when done, for "App Store" to work
