3 Things to Do Before Selling Your MacBook

Clean it thoroughly Wipe the screen and keyboard with a microfiber cloth. Use a soft brush or compressed air for the ports. A dirty laptop signals neglect and can cost you $50–100 in resale value.

Factory reset it properly Go to System Settings > General > Transfer or Reset > Erase All Content and Settings. This signs out of iCloud, disables Find My, and wipes the drive. On older Intel Macs, boot into Recovery and use Disk Utility first. Double-check that the Mac no longer appears in your iCloud device list.

Keep the original box The box signals a careful owner. Together with a clean, factory-reset MacBook and its charger, it tells buyers the laptop was loved. That’s the whole secret—skip the guides about specific macOS versions or benchmark tests.
