Global Homebrew PATH Prefix for macOS

Based on Homebrew’s FAQ you can set prefix in PATH for all GUI apps which is not enabled by default:

user$ sudo launchctl config user path "$(brew --prefix)/bin:${PATH}"
Configuration applied. You must reboot for changes to take effect.

According to this answer. The sudo launchctl config user path <...> command updates /private/var/db/com.apple.xpc.launchd/config/user.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>PathEnvironmentVariable</key>
	<string>/opt/homebrew/bin:/usr/bin:/bin:/usr/sbin:/sbin</string>
</dict>
</plist>

You can query launchd‘s current settings via:

launchctl getenv PATH

Related: You can also query the default PATH by executing:

sysctl user.cs_path

Test script with clear environment:

env -i git commit

Remove/Uninstall Rosetta 2 from Apple Silicon Macs

  1. Obtain a list of files/directories and LaunchAgents with: pkgutil --files com.apple.pkg.RosettaUpdateAuto
  2. Save them in a way that you can access them in the recovery
  3. Boot into recovery mode: Press and hold the power button on your Mac until “Loading startup options” appears.
  4. Open Terminal in recovery mode
  5. Run csrutil disable and confirm (temporary disable SIP)
  6. Reboot
  7. Delete the files listed at step 1 (in my case it was enough to delete /Library/Apple/usr/share/rosetta and /Library/Apple/usr/libexec with all their contents)
  8. Remember to empty the Trash
  9. Reboot back to recovery
  10. Run csrutil enable and confirm

Sample pkgutil output: 

$ pkgutil --files com.apple.pkg.RosettaUpdateAuto

Migrate Homebrew from Intel Macs to Apple Silicon Macs

Dump all your existing Homebrew packages:

brew bundle dump

If you’re using custom shell installed by Homebrew (ie. fish), change it back to bash temporarily:

chsh -s /bin/bash

You may also need to change this in System Preferences – Users & Groups (right click on your avatar and choose Advanced Options…)

Uninstall existing Homebrew (and all its packages):

curl -fsSL -o /tmp/uninstall.sh https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh
/bin/bash /tmp/uninstall.sh --path=/usr/local
