Tip: have lots of iOS \/ Mac devices in your house? And a Mac that’s usually on? Turn on “Content Caching” in Sharing prefs, and updates will be downloaded to all your devices from your Mac, saving time and bandwidth.<\/p>

(This used to be a macOS Server-only feature, but no more! The best part is zero configuration is needed on all of your devices — they’ll automatically find and go to your local Content Cache first.)<\/p>

(Also there are some hard-core settings probably useful to someone if you option-click the, er, Options… button.)<\/p><\/blockquote>\n\n

It’s nice in theory. Unclear that it works in practice. (Like 80% of what Apple ships these days: buggy? broken design?)<\/p>

However, shortly after I wrote the column noted above, content caching stopped working for me.<\/p>

[…]<\/p>

I decided to solve this, and found a detailed article<\/a> explaining the command line tool AssetCacheManagerUtil<\/tt>, which offers more controls than those found in the preference pane.<\/p>

[…]<\/p>

When you select a different drive to store the cache, that drive has to have the folder:<\/p>

\/Library\/Application Support\/Apple\/AssetCache\/Data<\/pre>
If it doesn’t exist? It stalls. This seems like a foolish testing error on Apple’s part: no message explains what’s going on, and there’s no text or other information that tells you a particular folder has to be on the destination volume you’re choosing for caching.<\/p><\/blockquote>","protected":false},"excerpt":{"rendered":"
