    One-liner To Grab Which macOS Caching Server You’re Using

    There’s a macOS tool called AssetCacheLocatorUtil located at /usr/bin/AssetCacheLocatorUtil. The output is in… stderr. Because stderr is so fun to work with (note that sed -i only works with stdin). So, to update the caching server(s) you are using and only print the IP address of those, you’d do the following: /usr/bin/AssetCacheLocatorUtil 2>&1 | grep guid | awk '{print$4}' | sed 's/^\(.*\):.*$/\1/' | uniq If you use Jamf Pro and would like to use this as an extension attribute, that’s posted here: https://github.com/krypted/cachecheck. I didn’t do any of the if/then there, as I’d usually just do that on the JSS.

    Tethered Caching of iOS Assets from macOS 10.12.4

    There is a new service in macOS, called Tetherator. Tethered-caching is a script that allows you to easily and quickly interact with the tethered-caching service, which has a few kinda’ cool options. This is on a client, and really speeds up all that crazy provisioning stuff you do. It can also check for the presence of a macOS Caching Server and use that as a source for the cache. The tethered-caching script is located at /usr/bin/tethered-caching. Before you do anything with the service, check the status. That’s done with the -s option (there’s also a -v option to get verbose): tethered-caching -s The results before activated should be as follows:…

    Precache Now Supports AppleTV

    Precache, available at https://github.com/krypted/precache, is a script that populates the cache on an OS X Caching server for Apple updates. The initial release supported iOS. The script now also supports caching the latest update for an AppleTV. To use that, there’s no need to include an argument for AppleTV. Instead, you would simply  run the script followed by the model identifier, as follows: sudo python precache.py AppleTV5,4
