Apple hardware holds its value, which is exactly why it attracts fakes. On marketplaces and auction sites you’ll run into three kinds of trouble: outright counterfeit shells built around cheap non-Apple parts, misrepresented Macs (a 2017 model sold as a 2020, or an 8GB machine listed as 16GB), and stolen or activation-locked units that can never be signed into. All three cost you money. This guide walks the exact checks we run on every Mac before it goes on our shelves, so you can do the same before you pay a private seller.
1. Verify the serial number on Apple’s own site
This is the single most powerful check and it takes 30 seconds. Ask the seller for the serial number (it’s printed on the bottom case and shown in Apple menu → About This Mac). Then go to checkcoverage.apple.com and enter it.
- Valid serial + a real model name (e.g. “MacBook Air (M2, 2022)”) = the machine is a genuine Apple product Apple has on record.
- “We’re sorry, but this serial number isn’t valid” = walk away. A counterfeit or a fabricated listing.
- Serial belongs to a different model than the listing = misrepresentation. If the site says 2019 and the seller says 2021, trust Apple.

2. Confirm the chip in About This Mac
If you can power the Mac on, open Apple menu → About This Mac. A genuine modern Mac reports an Apple chip (“Apple M1,” “Apple M2,” “Apple M3”) or a specific Intel processor. Red flags here:
- The About This Mac window looks off — wrong fonts, a Windows-style title bar, or a chip name that doesn’t exist. Counterfeits sometimes run a skinned Linux or Android build under a fake macOS wallpaper.
- The reported storage or memory doesn’t match the listing. On Apple Silicon, RAM is soldered and cannot be upgraded, so “16GB” that reports as 8GB means the listing is false.
- You can’t open System Settings, the App Store, or a real Safari — a hollowed-out fake will crash or show placeholder apps.
3. Watch the price
If the deal feels too good to be true, it is. A clean, genuine Apple-Silicon MacBook Air starts around $450 for a 2020 M1 and $549 for a 2022 M2 at a real refurbisher like us. A “brand-new M3 MacBook Pro for $400” on a marketplace is a scam — either a fake, a stolen unit, or a listing that vanishes after payment. Compare any price against a legitimate baseline; browse current Apple clearance pricing to see what genuine machines actually cost.
4. Inspect packaging, ports, and build
- Weight and feel: real MacBooks are dense unibody aluminum. A light, flexy, or plasticky chassis is a giveaway.
- Ports: the port layout must match the model. A “MacBook Pro” with a mismatched number of USB-C ports or a fake MagSafe is counterfeit.
- Keyboard and trackpad: the Apple font, the Force Touch trackpad (no physical click hinge on modern models), and backlight should all be correct.
- Box and accessories: Apple’s printing is crisp and centered. Blurry logos, typos (“Macintosh HD” misspelled, “Designed by Aple”), or a generic non-USB-C charger are red flags. That said, a genuine used Mac often ships without the original box — missing packaging alone isn’t proof of a fake.
5. Make sure it isn’t locked or stolen
Even a 100% genuine Mac is worthless to you if it’s tied to someone else’s Apple ID. Before you pay, insist the seller fully signs out: System Settings → [their name] → Sign Out, then erase the Mac. If Activation Lock or a firmware password blocks setup, do not buy it. See how to check if a used MacBook is stolen or activation-locked for the full walkthrough, and confirm battery wear with how to check battery cycle count while you have it open.
The simplest way to never get burned
Every check above is one we already run — serial verified against Apple, chip and specs confirmed, fully signed out and erased, battery health checked, and backed by our own warranty. When you buy a refurbished Mac from a real shop, the counterfeit risk drops to zero and you still pay far less than new. If a private deal ever feels wrong, it probably is: browse our verified Apple clearance instead, or read what to check when buying a used MacBook before you commit.
Quick FAQ
Can a MacBook serial number be faked? Scammers can print a fake serial on a case, but it won’t validate on checkcoverage.apple.com — that’s why the Apple-site check is the real test, not the sticker itself.
Does Apple make counterfeit MacBooks impossible to detect? No detector is perfect, but stacking the serial check, About This Mac, price sanity, and a physical inspection catches essentially every fake. A machine that passes all four is genuine.
Is a cheap MacBook always a scam? Not at all — a real 2020 M1 Air for around $450 is a legitimately great deal. “Cheap” is only a red flag when it’s far below what genuine machines of that model actually sell for.
