Scenario A – macOS Recognizes the Board Automatically

✅ Steps:

1. Connect the Dev Chip Board to a USB port on your Mac.

2. A dialog box will appear:

“Do you want to allow Silicon Labs CP2105 Dual USB to UART Bridge Controller to connect to this Mac?”

3. Click Allow or Always Allow.

4. To avoid this dialog showing every time:

• Go to System Settings → Privacy & Security → Accessories
• Change "Allow accessories to connect" to "Always Ask" or "Automatically" depending on your preference.
  

5. You can confirm that the board is recognized:

• Open System Information → USB
• Look for CP2105 Dual USB to UART Bridge Controller.

6. Optionally, use the Terminal:

ls /dev/cu.*

7. Check for /dev/cu.SLAB_USBtoUART.

Done! Now, open ChipInventor and you should see the message:
“✅ ChipLoader is Ready!”
