[https://app.travis-ci.com/github/audetto/AppleWin/builds/240458983](https://app.travis-ci.com/github/audetto/AppleWin/builds/240458983) from > I stopped the build after 12 minutes as it was still installing packages and spending a lot of time on packages I have not even requested. Using the default image, I am forced to set `update: true`, but this takes forever too. What is the best way to install packages on the osx image without spending all the credits? ---

You can cache Homebrew metadata, but it’s nontrivial. > ---

If you look at the travis file, I am using osx\_image: xcode12.5 This is better than the default image, but after 12 minutes it is still doing some “home brew system maintenance”. ---

I can improve the code in that SO answer into a turn-key solution if someone commissions me… ---

Consider adding `HOMEBREW_NO_INSTALLED_DEPENDENTS_CHECK=1` environment variable, like I mentioned [here](https://travis-ci.community/t/xcode-8-3-homebrew-outdated-error/3798/13). Also add `HOMEBREW_NO_AUTO_UPDATE=1` to be safe. Both are [documented](https://docs.brew.sh/Manpage#environment).
