Description of issue

I have an M1 mac. my terminal is arm. the results of the arch command are "arm64" yet when i install homebrew I get intel homebrew. Not sure what's going on.

I've uninstalled and reinstalled to to avail

[KaJashey]

Fixed it myself. I had to go to /usr/local and delete homebrew folder and the cellar folder for good measure. Shame that the uninstall script doesn't get those.

Now I have arm64 in brew config and and ready to go in brew doctor.

The uninstall script operates based on the current arch, which can be overridden with --path as recommended at https://github.com/Homebrew/install/blob/master/README.md#uninstall-homebrew

If you want to to uninstall Homebrew from a specific prefix (e.g. when migrating from Intel to Apple Silicon processors), download the uninstall script and run it with --path

Also see https://docs.brew.sh/Common-Issues#unintentional-dual-homebrew-installations for recommendation on migration from Intel to ARM.

Thank you. Is there any way to update the script so it uninstalls both locations as default? That behavior would be more in line of what I would expect from an uninstaller.

Is there any way to update the script so it uninstalls both locations as default? That behavior would be more in line of what I would expect from an uninstaller.

It would also greatly upset folks who install ARM64 Homebrew alongside Intel Homebrew to do a proper migration, and then run the uninstall script. I think "WTF!!!" would be the least vitriolic reaction when both installations disappear after all that hard work.

At the bottom of your brew config you'll see

Rosetta 2: true

Meaning your terminal is running in x86_64 mode, which is why everything is pointing to the Intel default prefix.
