Setting up Raspberry Pi with Terminal and Graphical Access

What you need:

• Raspberry Pi 5
• SD CARD (64 gig)
• Mac / Linux

1. OS Installation (Pi Imager)

First, let’s get the "brain" of the Pi ready using the Raspberry Pi Imager.

Insert an SD card to your mac. that a good option would be a 64gig, but you can go higher.

• Download: Pi Imager.
• Device: Open Pi Imager App and Select Raspberry Pi 5.
• OS: Select Pi OS Debian Trixie 64-bit. (or currently available stable OS)
• Customization Settings:
  • Host Name: raspberrypi (⚠️ DO NOT CHANGE!).
  • Username: pi (⚠️ DO NOT CHANGE!).
  • Password: 1234 .
  • Enable SSH: TRUE.

Other options can be kept as they are.

2. Connecting with Mac

Connecting via Ethernet while using a dedicated power supply is the "gold standard" for stability. It prevents those annoying "brownouts" or handshake issues common with USB-C gadget mode.

2.1. Hardware Connection (Mac Air M4)

• Adapter: Use a USB-C to Ethernet adapter for the Mac.
• Power: Plug the official Pi power supply into the wall and the Pi’s USB-C port.
• Data: Run an Ethernet cable from the Pi to the Mac's USB-C adapter.

2.2. macOS Internet Sharing

This makes your Mac act as a router for the Pi:

1. System Settings > General > Sharing.
2. Select Internet Sharing (Click the "i"—don't toggle it on just yet).
3. Share your connection from: Wi-Fi.
4. To computers using: Your USB 10/100/1000 LAN adapter.
5. Toggle Internet Sharing On.

You can open your terminal in your mac and use SSH to access your Pi.

SSH into Pi: Run ssh pi@raspberrypi.local from your terminal. Wait a bit. Give your Password. And you should be in.

3. VNC Configuration

Now, let’s get that remote desktop working so you don't have to hunt for a spare monitor.

1. Enable VNC: Run sudo raspi-config, navigate to Interface Options → VNC, and select Yes.

2. Viewer (PC/Mac): Download and Open "TigerVNC Viewer".

   • Link: raspberrypi.local.

   • User: pi.

   • Password: 1234.

4. Fixing TigerVNC "Color Mess" (Visual Artifacts)

If your screen looks like a neon fever dream (orange/pink artifacts), it's likely just a compression disagreement between the Pi 5 and TigerVNC.

The Fix: Adjust these settings in TigerVNC Viewer:

• Open Options → Compression tab.
• Uncheck "Auto select compression settings".
• Change Preferred encoding to Hextile or Raw.
• Set Color level to Full.
• Go to the Screen tab and uncheck "Allow JPEG compression".

5. Proper Shutdown Sequence

SD cards can be sensitive. Protect yours by following the "look for the red" rule.

1. Command: Run sudo shutdown -h now.
2. Wait: Your SSH session will close, but do not unplug yet.
3. The Watch: Watch the Green LED (ACT); it will flicker while writing logs.
4. Safe to Pull: Wait for the LED to turn RED.
