- This issue's title and/or description do not reference a single formula e.g.
brew install wget. If they do, open an issue at https://github.com/Homebrew/homebrew-core/issues/new/choose instead.
Provide a detailed description of the proposed feature
If installing an older bottle (e.g. a :sonoma bottle when running on macOS 15), brew should resolve dependencies according to the built bottle (perhaps by checking the tab) rather than what it thinks the dependencies on the current version of macOS that is being run.
We should continue to resolve dependencies as we currently do when installing bottles built for the current OS, because we still sometimes update a formula's dependencies without building new bottles when the change in dependencies has no effect on the built bottles (e.g. when a dependency was dropped a few versions ago but we only discovered this belatedly).
What is the motivation for the feature?
We are no longer bottling all formulae for Sequoia on Intel macOS. When macOS 16 is released, we are unlikely to provide bottles for all formulae for macOS 16 as well. This means that dependencies are not always resolved correctly when installing bottles built for older systems.
For example, [email protected] declares
uses_from_macos "expat", since: :sequoiaIf you try to install the :sonoma bottle on Intel macOS Sequoia, you will encounter errors because the bottle relies on Homebrew expat but you won't have Homebrew expat installed (since brew thinks the macOS-provided expat suffices).
How will the feature be relevant to at least 90% of Homebrew users?
It probably won't be, but it will still be relevant to a significant fraction of Homebrew users who are running an Intel Mac.
What alternatives to the feature have been considered?
We could:
- do nothing
- bottle the affected formulae on new macOS versions
Note that it's not always clear what the affected formulae are, so doing the second feels less sustainable.
