Buying a Used MacBook: What to Check Before You Pay
A used MacBook checklist: the exact model and chip, Activation Lock, device management, battery cycle count, the drive and every port, before you pay.
On this page
A used MacBook is one of the better buys in used tech. Apple silicon laptops stay fast for years, and a two or three year old MacBook Air or Pro costs a lot less than a new one. But a laptop hides more than a phone does. The chip, the memory and the storage are fixed for the life of the machine, and a Mac can be locked to someone else's account or to a company in ways that do not show until you erase it.
This checklist takes about twenty minutes. It follows Apple's own support pages, plus what we look at on every Mac we sell.
Before you meet: the exact model
Ask the seller for the model name and the serial number. On the Mac, the Apple menu, then About This Mac, shows the model name, the chip, the memory and the serial. Apple's pages to identify a MacBook Air and to identify a MacBook Pro list every model with its year, colors and the newest macOS it can run. That last line matters for an older Intel model: check how long it will keep getting updates before you pay for one.
Three numbers decide what a MacBook is worth and whether it suits you:
| What | Where to see it | Why it matters |
|---|---|---|
| Chip | About This Mac | An M1, M2, M3 or later Apple silicon chip, or an Intel processor. The Pro and Max versions carry more cores |
| Memory | About This Mac | On Apple silicon it is part of the chip and cannot be added later |
| Storage | System Settings, General, Storage | It cannot be upgraded later either |
Two MacBook Pros with the same name can have different chips. If a listing says only "MacBook Pro 14 inch 2023", ask which chip and how many cores, because the price difference between builds can be large.
Activation Lock: the check that matters most
Activation Lock is Apple's anti-theft lock. Apple's Activation Lock for Mac page explains that on a Mac with Apple silicon or the T2 Security Chip, it is on whenever Find My is on, and the owner's Apple Account password is then needed to turn off Find My, erase the Mac, or reactivate and use it.
Ask the seller to turn it off in front of you: the Apple menu, System Settings, their name, iCloud, then Find My Mac, and turn it off with their password. If the Mac is offline, they can remove it from their account at iCloud.com/find.
If a seller cannot turn off Find My, do not buy the Mac. A MacBook still tied to someone else's Apple Account can stop working for you the moment it is erased.
Device management
Companies and schools manage their Macs remotely. A managed Mac can have settings and apps pushed to it, and a Mac enrolled through a company's Apple program can enroll itself again after an erase. In System Settings, open General, then Device Management, to see any management profiles. On older versions of macOS it is under Privacy & Security, then Profiles. On a personal Mac this is usually empty.
If you erase a Mac and setup shows a Remote Management screen naming an organization, the Mac still belongs to that organization's management.
Some used Macs, including some we sell, have had a company's management enrollment bypassed. We say so on every listing in plain words, MDM BYPASSED, and price the Mac for it. Such a Mac must not be erased or have macOS reinstalled, because a full restore can bring the enrollment back. If that limitation does not suit how you use a laptop, pick a listing without it.
Battery
A MacBook battery is rated in charge cycles. Apple's page on battery cycle count for Mac laptops explains that a battery is designed to keep up to 80 percent of its original capacity at its maximum cycle count, and lists that maximum for each model. For recent MacBooks it is 1,000 cycles.
To read the count, hold the Option key, click the Apple menu, choose System Information, then Power. The cycle count is under Battery Information. In System Settings, Battery shows the battery's health and, on recent models, its maximum capacity as a percentage. A Mac that says Service Recommended needs a new battery soon, and the price should reflect it.
The drive
A MacBook's storage wears with use, and a failing drive is expensive to fix on Apple silicon. Check that the storage in About This Mac matches the listing. A drive health app reads the drive's own health report; on our listings, when we have read a Mac's drive with DriveDx, the reading is printed with the listing.
Test the hardware
| Check | How | What you want |
|---|---|---|
| Body and hinge | Look at the lid, corners and the hinge in good light | No dents that bend the case, and a lid that holds its angle |
| Display | Open a plain white page, then a black one | Even brightness, no dead pixels, no pressure marks |
| Keyboard | Type every key in a text app | Every key registers once, backlight works |
| Trackpad | Click across the whole pad and drag a window | Clicks register everywhere |
| Ports | Charge from each USB-C or Thunderbolt port, and MagSafe if it has one | It charges from every port |
| Speakers and mics | Play a video and record a voice memo | Clear sound both ways |
| Camera | Open FaceTime or Photo Booth | A clear picture |
| Touch ID | Add a fingerprint in System Settings | It enrolls and unlocks |
| Wi-Fi and Bluetooth | Join your phone's hotspot, pair headphones | Both connect |
When it is your turn: the erase
On a Mac with no management bypass, the seller should sign out and erase it before handing it over. Apple's erase your Mac page shows the steps: System Settings, General, Transfer or Reset, then Erase All Content and Settings. After that, setup should ask for nobody's account but yours.
Buying a Mac from iPhones.LA
Every Mac on our shop is checked on the bench for iCloud lock and device management before it is listed. The listing title states the chip and its core counts, and a nano-texture display where the Mac has one. The battery is read off the Mac, the drive reading is printed where we have taken it, and any bypassed management is named on the listing in plain words.
Every used or open box Mac comes with a 60-day warranty on factory hardware defects. Pick it up free in Long Beach, get it delivered across Los Angeles and Orange County, or have it shipped anywhere in the US, insured and signed for. How buying from iPhones.LA works has every step.
Selling your old laptop to pay for this one? We buy MacBooks and other Macs too; selling an iPad, MacBook or Apple Watch explains how they are priced, and the sell page gives you a number.

Frequently asked questions
What should I check before buying a used MacBook?
The exact model and chip, that Find My is off and Activation Lock is gone, any device management profiles, the battery cycle count and health, the storage, and every key, port, speaker and camera.
How do I check a MacBook's battery cycle count?
Hold the Option key, click the Apple menu and choose System Information, then select Power. The cycle count is listed under Battery Information. Apple's page lists the maximum count for each model.
Can I upgrade the memory or storage on a used MacBook later?
Not on an Apple silicon MacBook. The memory is part of the chip and the storage cannot be upgraded, so buy the size you need now.
What does MDM bypassed mean on a used Mac?
The Mac was enrolled in a company's device management, and that enrollment has been removed. It is sold that way and must not be erased or have macOS reinstalled, because a full restore can bring the enrollment back. We name it on every listing where it applies.
Is it safe to buy a used MacBook if the seller cannot turn off Find My?
No. With Find My on, Activation Lock keeps the Mac tied to the seller's Apple Account, and their password is needed to erase it or set it up again.
