Inspect the iMac before paying. Check Apple Account removal, display, storage, keyboard, mouse, ports, Wi-Fi, speakers, camera, and performance.
Only continue if the iMac passes these major checks:
The iMac should show the setup screen after reset. It should not ask for the seller’s Apple Account or password.
Go to Apple Menu → About This Mac. Confirm model, year, chip/processor, RAM, serial number, and storage.
Check brightness, color, dead pixels, lines, flicker, screen burn, dark spots, and cracked glass.
Type all keys, test trackpad or Magic Mouse, Bluetooth connection, charging, and pairing.
Connect to Wi-Fi and pair a Bluetooth device to make sure wireless hardware works.
Open FaceTime/Photo Booth, test the webcam, record audio, and play music to test speakers.
Check USB-C/Thunderbolt, USB-A if available, headphone jack, Ethernet if available, and SD card slot if available.
Open multiple apps, Safari, settings, and storage info. Watch for freezing, overheating, fan noise, or random restart.
Inspect stand, hinge, frame, glass, power cable, dents, scratches, and signs of liquid damage.
Check included keyboard, mouse/trackpad, power cable, box, receipt, and any adapters promised by the seller.
Check each item before giving payment.
