Presented without much commentary since I stopped once {ggrepel} and {graphlayouts} failed (RStudio doesn’t support it yet, either, which I knew).

The following steps will get you a fully working and STUPID FAST fully native ARM64 M1/Apple Silicon R setup with {tidyverse} and {rJava}.

Just remember, that if you need RStudio (or anything that links against the x86_64 R dylib) you’re going to be reverting this to get stuff done.

# Setting up ARM64 R on Apple Silicon/M1

# uninstall x86_64 homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

# make sure you unalias "brew" if you aliased it with "arch"

# install arm64 homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

# do what it says re: paths

# install wget (to make sure stuff is working)
brew install wget
