thats the problem…
Migration assistant moved your Intel based Homebrew config to the M1 so homebrew gets confused.
Run these commands
arch -x86_64 /usr/local/bin/brew bundle dump --global
This takes all your current Homebrew installations into a logfile. you can then search through the logfile and prune out anything you dont normally use
arch
This is just to ensure your terminal is running arm64. if it isnt then stop here.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
This just installs Homebrew and since you are on a M1 using an ARM64 terminal it will ensure it installs correctly
/opt/homebrew/bin/brew bundle install --global
This reinstalls your former applications. You’re gonna get an error message about Homebrew core. it can be ignored.
Sudo /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)" -- --path=/usr/local
This removes the Intel version of Homebrew.
Then, try your Proxmark commands and see what occurs.
