Physical Inspection

   • Look for anti-reflective coating wear, scratches, and hinge functionality.

Computer Testing

1. Connecting to Wi-Fi:

   • Ensure the computer is connected to a Wi-Fi network.

2. Specifications Check:

   • Click the Apple logo > About This Mac to verify:
     • Processor, RAM, serial number must match the listing.
   • Hold down Option/Alt key > click Apple logo > System Information > Storage to check hard drive info (SSD, HDD, Fusion).

3. Photobooth Test:

   • Open Photobooth, switch to video mode, record, and playback to check video, audio, and microphone functionality.

4. Bluetooth Check:

   • Go to System Settings > Bluetooth, connect a device to ensure pairing works.

5. Battery Health Test:

   • Download "Cocoa Nut Battery" from Safari to check battery health and cycle count.
   • High cycle counts (>400) or health <85% may warrant negotiation.

6. Keyboard Testing:

   • Open Notes and type to check for sticking or double-registering keys.
   • Test keyboard backlight using System Settings > Keyboard.

9. Port Testing:

   • Test USB and USB-C ports with accessories to ensure they register.
   • Check SD card slot functionality if applicable.
   • Test charging functionality with the charger.

Software & Security Checks

1. Apple ID Verification:

   • In System Settings, ensure the Apple ID section shows "Sign In" to avoid previous owner’s data.

3. Users & Groups:

   • Ensure only one user exists on the computer and other accounts are signed out.

4. Profiles Check:

   • In Security & Privacy settings, check for any school/work profiles and ensure removal.

Final Steps

1. Factory Reset:

   • Important to reset the computer to remove the previous owner's data.
