# Microsof's JDK is broken, Microsoft has been contacted about this.
# MYJDK=https://github.com/microsoft/openjdk-aarch64/releases/download/16-ea%2B10-macos/jdk-16-ea+10-macos+aarch64.tar.gz
# curl -sL $MYJDK | tar xvz --strip 1 -C ~/Applications/openjdk

#### USE THIS ####
# Get Zulu's JDK instead (it's not a tarball, so it can't easily be scripted, sorry!)
# - Manually download from here: https://cdn.azul.com/zulu/bin/zulu11.43.1007-ca-jdk11.0.9.1-macos_aarch64.zip
# - Extract to ~/Applications/
# - Rename from "zulu11.43.1007-ca-jdk11.0.9.1-macos_aarch64" to "openjdk"

# If needed, unquarantine
sudo xattr -r -d com.apple.quarantine ~/Applications/openjdk

# Get homebrew ready
sudo mkdir -p /opt/homebrew && sudo chown -R $(whoami):staff /opt/homebrew
