What to check before buying a used MacBook on Marketplace or Kijiji

Activation Lock on Macs

Macs with Apple silicon (M1 and later) or Apple’s T2 security chip, which covers most Intel MacBooks from 2018 on, support Activation Lock (Apple). It switches on with Find My, and it survives an erase: a locked Mac that has been wiped will ask for the previous owner’s Apple Account at setup, and only that owner can remove it. AppleInsider notes that Apple will only help with a proof of purchase from the original owner (AppleInsider), which you won’t have.

There is no public website where you can type a serial and see the lock status. The check happens on the Mac, in person:

1. Read the status. Hold the Option key, open the Apple menu, choose System Information, then Hardware. “Activation Lock Status: Disabled” is what you want. “Enabled” means Find My is still on for the seller’s account.
2. Watch the seller sign out. System Settings > their name > Sign Out. That turns off Find My and the lock.
3. Watch the erase. On Apple silicon and T2 Macs with a recent macOS: System Settings > General > Transfer or Reset > Erase All Content and Settings.
4. Start setup yourself. Join Wi-Fi and go a few screens in. No request for an Apple ID and no Remote Management screen means you are clear.

A Mac that shows “This Mac is locked” or asks for the Apple ID used to activate it is not for sale, whatever the seller says. The same rules for iPhones, iPads and watches are in iPhone Locked to Owner.

Company-owned Macs and device management

Companies and schools register their Macs with Apple Business Manager or Apple School Manager. When one of those Macs is erased and set up again, it checks in with Apple, finds its owner, and shows a Remote Management screen with the organization’s name before it joins their device management (Apple). A wiped Mac that looks perfectly normal on the seller’s desk can do this the first time you set it up at home.

A Mac still enrolled isn’t really yours. The organization can push settings, restrict software, lock or wipe it remotely, and only the organization can release it. Look for:

• A profile. System Settings > General > Device Management (Profiles on older macOS). Anything listed there came from an organization.
• Asset tags and engraving. A company sticker, an inventory number, or a laser-etched name on the bottom case.
• A story that doesn’t fit. “Got it from work when I left” can be true, but ask whether IT released it. A seller with several identical MacBooks is liquidating stock from somewhere.

On a Mac that is running and signed in, the Terminal command sudo profiles show -type enrollment asks Apple whether the serial is registered to an organization. If it returns an organization’s configuration, walk away unless the seller can show it has been released.

Hardware checks

Bring a USB-C (or MagSafe) charger you trust, a USB stick and earbuds. Fifteen minutes is enough.

1. Battery cycles and condition. Option + Apple menu > System Information > Power shows the Cycle Count and Condition. Most recent MacBooks are rated for 1,000 cycles (Apple’s table lists every model). System Settings > Battery shows the health, and “Service Recommended” means a replacement is due. Price that in: a battery service is a real cost.
2. Screen. A white page for dead pixels and pressure marks, a black page for backlight bleed. On older Retina MacBook Pros, look for worn patches in the anti-reflective coating. Open and close the lid slowly while watching the bottom edge for flicker; some 2016 and 2017 13-inch MacBook Pros developed a backlight cable fault that shows up this way.
3. Keyboard. Type every key in a text editor. MacBook, MacBook Air and MacBook Pro models from 2015 to 2019 used the “butterfly” keyboard, known for sticking and repeating keys, and Apple’s free repair program for it has ended (AppleInsider).
4. Trackpad. Click in every corner, and try Force Click if the model has it.
5. Ports and charging. Plug the charger into each port and confirm it charges; try your USB stick in each port. Check that the included charger’s wattage suits the model: an underpowered charger charges slowly.
6. Speakers, microphone, camera. Play a video, record a voice memo, open Photo Booth.
7. Apple Diagnostics. On Apple silicon, shut down, hold the power button until startup options appear, then press Command-D. On Intel Macs, restart and hold D. It reports faults in plain codes.
8. Wi-Fi and Bluetooth. Join a network and pair your earbuds.

Model and specs

“MacBook Pro, i7, 16 GB” describes half a dozen very different machines. Open Apple menu > About This Mac: it shows the model and year, the chip, the memory and the macOS version. Storage is under System Settings > General > Storage. Then enter the serial at Apple Check Coverage, which names the model and says whether the purchase date is valid and whether any warranty or AppleCare remains.

Memory and storage on modern MacBooks can’t be upgraded later, so buy what you’ll need. And for Intel Macs, keep an eye on software support: Apple has said macOS Tahoe 26 is the last major release for Intel-based Macs, which lowers what they are worth.

Stolen MacBooks

There is no IMEI on a MacBook and no public stolen-laptop lookup, so you rely on signals:

• Activation Lock disabled and the seller signing out willingly. A thief can’t sign out of an account they don’t have.
• A receipt or order confirmation whose serial matches the Mac.
• A seller profile with some history, a meeting place that isn’t a parking lot, and a price that isn’t suspiciously low.
• Hesitation to boot it, sign out or erase it in front of you.

If something feels wrong, leave it. Laptops reported stolen are sometimes recovered from buyers, and the money is rarely recovered.

Other laptops (Windows and gaming laptops)

The same logic applies with different menus. Enter the BIOS or UEFI setup at startup to make sure it isn’t password-protected. Look for company asset tags and for “managed by your organization” in Windows Settings. Check that Windows is activated (Settings > System > Activation). Run powercfg /batteryreport in a command prompt for the battery’s design and full-charge capacity. For a gaming laptop, run a GPU stress test while you watch temperatures, as described in buying a used GPU or gaming PC.

What a used MacBook should cost

Compare the same chip, memory and storage, not the same name. An M1 MacBook Air with 8 GB and 256 GB is a different market from one with 16 GB and 512 GB. Look at ten or more listings across Marketplace and Kijiji, then eBay sold prices for completed sales. Apple’s refurbished store, which includes a warranty, is the ceiling for a private sale. Adjust down for a battery near its cycle limit, dents, keyboard faults, a missing charger, or an Intel model near the end of its updates. See how to judge a fair price.

Searches and alerts

Search by chip and size: “macbook air m2”, “macbook pro 14 m3”, “macbook air 13 m1 16gb”. In Quebec, try “portable apple” as well. Keep out “for parts”, “icloud locked”, case, sleeve, charger and keyboard cover. Well-priced MacBooks sell quickly, so a watched search for one chip and size pays off; see new listing alerts.

With Sift

On a computer, Sift recognizes MacBook listings and switches on its phones and devices kit, with a “Device” header on the details card. It reads what the seller wrote, in English and French: an Activation locked flag for wording like “iCloud locked”, “activation lock” or “locked to owner” (negations such as “not iCloud locked” are ignored), a Still financed flag for payment-plan wording, and an AppleCare good sign. Check elsewhere opens eBay sold prices, Google Lens on the photo and the same search on the other site. There is no IMEI link, because MacBooks have no IMEI. Start a hunt > Phone in Options > Presets saves a preset with the parts block words on, which works for laptop hunts too.

Sift can’t see a Mac’s Activation Lock or management status; only the checks above can. It runs in Chrome, Edge and Brave on a computer and isn’t affiliated with Apple, Meta or Kijiji.
