| Rerun the Homebrew installer under Rosetta 2. | |
| To rerun the Homebrew installer under Rosetta 2, | |
| select your Terminal app in Finder and click Get Info. | |
| Make sure that "Open using Rosetta" is checked. | |
| Then quit and re-open your Terminal. |

@claui Does this force your Terminal to always open in Rosetta? I'm wondering if there are any nicer ways than this as it seems like this may not be what people want, I dunno. If not: no worries.

Yes, it forces the Terminal to always open in Rosetta.
It may not always be what people want but I’d still prefer to recommend it than recommending to prepend arch -x86_64.
The latter may be more convenient but:
- it’s extremely easy to forget during daily use, and
- imho it’s also kind of awkward to describe.

What if Rosetta is not yet installed (as it sounds like it isn't/won't be by default)?
It may not always be what people want but I’d still prefer to recommend it than recommending to prepend
arch -x86_64.
Doing this and then having something like a rosettabrew alias that runs arch -x86_64 brew feels like it'd be nice.

What if Rosetta is not yet installed
Maybe add a link that tells people how to install Rosetta upfront. Like:
If Rosetta is not installed, please follow the instructions at <url>

@MikeMcQuaid Fyi, Homebrew/brew#9126 includes a few suggestions. I plan to apply those here once they’re merged there.
Refuse to install unless on Intel processors. If we're on macOS ARM then output a custom message letting people know they can use Rosetta.

Can we exclude the whole block when HOMEBREW_ON_LINUX is 1? Just to make sure this Mac-specific code is not run there?

@iMichka sorry the page autorefresh didn't show this until after I merged 😬. This should be there still on ARM on Linux because it's an unsupported configuration.

Yes it is, but it will tell people to use Rosetta on ARM linux I guess?

This needs to be merged and in a tagged release before Big Sur is released so please prioritise testing and reviewing this ASAP CC @claui @Bo98 @fxcoudert @mistydemeo
