How to consider processor architecture when installing? about homebrew-bundle

[colindean]

I see what you're trying to do now, sorry about that.

You can use Hardware::CPU.arm? and Hardware::CPU.intel? but n.b. these are not explicitly part of the Brewfile DSL so they're not guaranteed to work perpetually— they probably will for the foreseeable future.

I use this several of my own Brewfiles:

if OS.mac? && Hardware::CPU.arm?
  # OS-level dependency for pyodbc
  brew "unixodbc"
end

N.b. that the AlDente FAQ lists support for Intel Macs under the Is my MacBook Model supported? section and the DMG for v1.22 ships a universal binary.

Yes, this is the best bet, I'd rely on this.

Many if not most if not nearly all formulae and casks handle this. Homebrew Bundle just tells Homebrew what formulae and casks and whatnot to install. Those will then install the correct version for the architecture.

If you find this is not the case, double-check the formula/cask and then upstream to be sure that the software supports your architecture.

In this case each app only supports a single architecture, and naively trying to install one on the wrong architecture will make Homebrew fail.

I'm not sure what will happen in homebrew-bundle's case.

But you could just evaluate the output of uname -m to make sure it's arm64 or x86_64, it seems.

as @colindean mentioned, this isn't something homebrew-bundle handles but offloads to the formula/cask. if you're seeing issues, the best place to investigate is the formula.
