go to applications folder, select terminal app, under its options, uncheck Rosetta and try. Got the same issue fixed earlier.

Thanks - but my Open using Rosetta option currently isn't checked.

Thanks @aespeiuk22! I found a discussion on Discord that referenced #1078, and it looks like the issue is that my homebrew was installed for Intel. So I have to uninstall and re-install it :( That would be really useful information to include on the page about setting up Mojo on a newer Mac...

@jackos Please note.

Hi @kkrugler yes has been a common issue, we should include an error message, uninstalling and reinstalling is the way to fix: https://github.com/Homebrew/install#uninstall-homebrew

@bzcheeseman @zbowling fyi lots of users have x86 homebrew installed on their arm64 machine, can we guide them to the above instructions in that scenario or just show the steps to uninstall and reinstall?

[kkrugler]

Hi @jackos - thanks, that worked! Though I had to edit the brew-uninstall.sh script to get it to work, my (ancient) brew install was located at /usr/local/homebrew, and I had to manually remove this directory when the uninstall was finished.
