The Final Checklist Before You Hand Over Your Mac

Everything's agreed. The price is set, the buyer is ready, the box is half-packed — and this is exactly the moment where a Mac sale most often goes wrong. Not because of a scammer or a shipping mishap, but because the seller, eager to be done, skips a step: they forget to sign out of an account, or they wipe the machine in the wrong order, or they let it go before the money is truly theirs. This final checklist exists so the last five minutes don't undo everything.

Run through it in order every time, whether you're handing the Mac to someone in person or dropping it at a shipping counter.

1. Back up before you touch anything else

Once you erase, it's gone — so the backup comes first. Use Time Machine to an external drive, or make sure everything important is already in iCloud or copied elsewhere. Don't forget the things that don't live in your Documents folder: browser passwords and bookmarks, authenticator apps, license keys for software, and photos that never made it to the cloud. If you're moving to a new Mac, this backup is also what you'll restore from, so it's doing double duty.

2. Sign out of your accounts

This is the step people most often botch, and it's the one that causes locked machines. Sign out of iMessage first, then sign out of iCloud — signing out of iCloud is what turns off Find My and releases Activation Lock. If you skip this and just erase, the Mac can stay tied to your Apple ID and strand the next owner at a login only you can clear. Apple's own guide to preparing a Mac for trade-in or sale spells out the full order, and it's worth following exactly rather than from memory.

The accounts to clear

• iMessage — sign out in the Messages app settings.
• iCloud / Apple ID — sign out in System Settings; this releases Find My and Activation Lock.
• Other services — deauthorize the Mac in any apps that limit installs, and sign out of anything storing personal data.

3. Erase the Mac

With your accounts signed out, erase the machine. On Apple Silicon and T2 Macs, the built-in Erase All Content and Settings option is the cleanest route — it wipes your data and returns the Mac to a fresh setup screen. On older machines, restart into recovery, erase the drive, and reinstall macOS. Either way, the machine should end at the setup assistant, ready for its new owner, with none of your data behind it.

4. Confirm it's clean

Don't trust the erase screen alone. Check your Apple account's device list from your phone or another computer and make sure the Mac no longer appears — that's your proof Activation Lock is off and the machine is genuinely disassociated from you. Wipe the physical machine down while you're at it, and gather any extras that add value: the original box, the correct charger, and any repair records.

5. Don't let go until you're actually paid

The last item isn't about the Mac at all — it's about the money. In a person-to-person sale, this is where scammers strike, and the FTC's advice on how to avoid a scam when selling online is the whole discipline in a sentence: don't accept a payment for more than your price, don't share verification codes, and make sure funds have genuinely cleared before the item leaves your hands. A screenshot of a "pending" transfer is not payment. Real, settled money in your account is the only green light.

The full list, at a glance

• Backed up (Time Machine or cloud), including passwords and license keys.
• Signed out of iMessage and iCloud; Find My off.
• Mac erased and sitting at the setup screen.
• Confirmed gone from your Apple ID device list.
• Box, charger, and any records gathered.
• Payment fully cleared before hand-off.

Where a dedicated buyer simplifies the ending

The first four items are good practice no matter who buys your Mac — you should always back up, sign out, and erase. It's the fifth one, the payment, that carries the real risk in a private sale, and that's the part selling to a dedicated buyer removes. With Encore you get an instant online offer in about 30 seconds, a free prepaid, insured shipping label, and payment once the Mac arrives — the accepted offer is what you're paid, with no chargeback exposure and no stranger to meet at the end of it. Because it buys broken and older units too, even a machine you can't quite get cleaned up still has somewhere to go. It won't always beat a flawless private sale on headline price, but it takes the most anxious step off the list. Once your checklist is done, it's easy to see what your Mac is worth as-is and decide from there.
