How to install Homebrew on your ARM based Mac
Unfortunately, homebrew isn’t quite ready for your brand new mac… Performing the typical install seen on their site will present you with something like the opposite.
I’m sure the brew team are hard at work, and the (yet) in the response seems like they may be following up with an update soon.
But what about those of us who have excitedly received their ARM-based macs today?
Well, there are two options, install under Rosetta 2 OR install on ARM.
Rosetta 2
A̶t̶ ̶t̶h̶e̶ ̶t̶i̶m̶e̶ ̶o̶f̶ ̶w̶r̶i̶t̶i̶n̶g̶,̶ ̶I̶ ̶c̶a̶n̶’̶t̶ ̶f̶i̶n̶d̶ ̶a̶ ̶g̶u̶i̶d̶e̶ ̶o̶n̶ ̶h̶o̶w̶ ̶t̶o̶ ̶i̶n̶s̶t̶a̶l̶l̶ ̶a̶ ̶C̶L̶I̶ ̶a̶p̶p̶l̶i̶c̶a̶t̶i̶o̶n̶ ̶v̶i̶a̶ ̶R̶o̶s̶e̶t̶t̶a̶ ̶2̶.̶ ̶K̶e̶e̶p̶ ̶a̶n̶ ̶e̶y̶e̶ ̶o̶n̶ ̶h̶t̶t̶p̶s̶:̶/̶/̶b̶r̶e̶w̶.̶s̶h̶/̶ ̶f̶o̶r̶ ̶a̶n̶y̶ ̶f̶u̶t̶u̶r̶e̶ ̶u̶p̶d̶a̶t̶e̶s̶.̶
To install via Rosetta 2 simply issue the following install command
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
