I have installed Mac OSX server onto one machine. Caching is enabled.

How do I now configure a client Mac on the same network to start using this cache for both web browsing and software updates?

I have tried System Preferences -> Network -> Advanced -> Proxies and enabled "Web Proxy (HTTP)" and entered the local IP of the machine running Mac OSX Server ( and the port number 49524 but this doesn't work. I just see a blank white screen when I try and view any web page in Chrome.

Does anybody know the correct set up instructions for the clients? There appears to be very little to help me out on Google.

The Caching service is no web-proxy. It just provides software updates, purchased apps from the Mac App Store, iBooks and iTunes U content.

When you first enable the caching server, it registers its public IP and private IP with Apple. If a client tries to download a software update or an app from the same public IP as the server, Apple “introduces” the client to the server automatically. Therefore client configuration is not required.

If you want a proxy server install Squid/Squidman

  • That means caching will not work if web-proxies are enabled. Then what is recommended to store updates in server?

  • @Nagarjun Caching (as in Apple's Caching Server) should still work even if you use a web-proxy. The person asking just tried to use the Caching Server as a web-proxy - which doesn't work.

  • @Nagarjun Did you install and configure an OS X Server.app?

    @Chris IMHO DHCP doesn't have to be enabled. Multicast DNS (mDNS) & DNS Service Discovery (DNS-SD) has to work though. You may check this with dns-sd -B _aaplcache._tcp local.

It is to a point transparent. Here is a good quote from the Apple article about caching server

"and by default is configured to support clients that share the same public IP address behind a NAT."

As long as you have your clients set up behind the same NAT it will download from Apple for the first download and every client after that will then download form the Caching server. Take a look at the picture below from Apple's documentation. So in the end their is no client side setup needed if your network is setup correctly.

  • thank you for the reply. This is odd. The IP of my server is My client is They are on the same network and I've left the network proxy settings empty (default). Browsing the internet works but nothing is being shown on the "Caching" section of the server.

  • Sorry, I must have confused your article. Caching server has nothing to do with browsing the internet. Its purpose is for Mac app store downloads and updates. I think your looking for something else if internet browser caching is what your after.

    My understanding was that "Caching" was for web browsing and the separate menu option called "Software Update" (under the advanced menu) was for the downloads/updates. I am keen to achieve both.

  • No. Read the article I linked above from Apple. The software Update under advanced is a whole different server applet.
