Setup Raspbian Buster

I'm using debian 10 as my daily so these are *nix commands. Mac should work with these too but you're on your own if you're using Windows. Goal for me is to make a headless raspberry pi I can SSH into and connect to my network using Ethernet. You should be comfortable in command line if you choose to follow this guide.

Go to https://www.raspberrypi.org/downloads/raspbian and download Raspbian lite archive
unzip the image
Plug in sdcard. Run lsblk to see drives and mount points. Likely, the sdcard will show up in /dev/sda or /dev/sdb and may have some partitions like /dev/sda1 and /dev/sda2.
If partitions are mounted, unmount all of them. Ex: umount /dev/sda1 and umount /dev/sda2
Copy the raspbian image to the sdcard with sudo dd if=RASPBIAN_IMAGE_FILE.img of=/dev/sda bs=4M
Run sync to ensure the written contents are flushed
OPTIONAL: To start ssh server on boot, Unplug sdcard and reinsert to remount new partitions. You'll have two with raspbian.

Disable:

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

Enable:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

The only game I play on the Mac Mini connected to our TV is Cuphead.

I wanted the game to launch automatically when I turn on one of our Nimbus game controllers, which connect via Bluetooth.

This is how:

Save the .scpt file below as e.g. ~/Library/Scripts/LaunchCupheadIfControllerIsConnected.scpt
- In the .scpt, change "Nimbus" if your Bluetooth game controllers have some other name.
Save the .plist below as e.g. ~/Library/LaunchAgents/henrik.launch_cuphead_if_controller_is_connected.plist
In the .plist, change media to whatever your username is.

Enable macOS Server Performance Mode

Performance mode changes the system parameters of your Mac. These changes take better advantage of your hardware for demanding server applications.

A Mac with macOS Server that needs to run high-performance services can turn on performance mode to dedicate additional system resources for server applications. Note, however, that performance mode can be enabled even without macOS Server being installed to achieve similar benifits for other high-performance services.

sudo nvram boot-args="serverperfmode=1 $(nvram boot-args 2>/dev/null | cut -f 2-)"
sudo reboot
