High Sierra Content Caching

Neil Laubenthal
Does content caching do any preemptive downloads? I’ve set it up on my always running Mac mini…but as we live in the RV and have limited and costly bandwidth we only download apps and such when we’re on campground wifi and not our metered Verizon MiFi. I’ve set the Mini up as the only caching server on my network and while caching is a good thing for updating our multiple iOS and macOS devices any inadvertent downloads could end up running the Verizon bill higher than expected.

On the mini I’ve got Caching on for all content and the Share Internet Connection box checked. In App Store preferences I’ve got automatically check for updates and Install system data files and security updates checked but other downloads unchecked. 

I think that setup this way the mini will cache anything that’s downloaded by a laptop or iOS device but not check on it’s own…however it appears from the bandwidth usage on my router that the mini might be using more bandwidth than before I started the caching server…so I figured I would verify before I end up spending more Verizon bits than anticipated.

Thanks.

Supposedly. Or at least it was supposed to when it was part of Server.

If you are at times on a metered connection I would get a utility like Trip Mode that can completely disable things you don't want to run on your metered connection.

Plus one for tripmode - I was just about to suggest it, as I used to pay per kB for my ADSL line during the day in Scotland and a random update would be expensive.

Little Snitch will tell you more about what is happening but tripmode is plug n play. It switches stuff off by default so you enable what you want to have network access.

Thanks…I’ll check out Trip Mode. I couldn’t really find any details at from apple.com on the under the head details of caching. We’re not often on our Mifi which is metered but during the summer travel season we’re on it enough that watching the bits is one of the things I do anyway…hopefully I’ll be able to figure out whether it’s downloading things without me knowing about it.
