Activation Lock on a Used Mac? Check
The used MacBook is a great price — until you turn it on and it demands someone else's Apple ID. Activation Lock ties the Mac to its owner's account, and no legitimate trick bypasses it. A locked used Mac is an expensive paperweight. Check before money changes hands, every time.

TL;DR / Quick Fix
Quick fix: before buying a used Mac, ask the seller to erase it and remove it from their Apple ID while you watch — then start it and confirm no Activation Lock screen appears. Never buy a Mac still locked to someone else's account. No legitimate seller refuses this check.
Follow these steps
- Ask the seller to erase in front of you. The seller opens the erase flow, signs out of their Apple ID, and erases. Watch it happen — promises are worthless here.
- Boot to the welcome screen yourself. After erasing, the Mac should show the language-selection Hello screen with no Apple ID prompt. That is the proof.
- Check the seller removed it remotely too. On their other device, the Mac should be gone from their Apple ID device list. Belt and suspenders — do both checks.
- Walk away from any lock screen. If setup demands an Apple ID you do not own, stop. No story — 'forgot the password,' 'my cousin's account' — makes this Mac buyable.
- Get a receipt with the serial number. Legitimate sellers provide one. It protects you if the Mac is later reported stolen.
- Set up Find My immediately after. Once it is yours and erased, enable Find My Mac during your own setup — your lock now protects your Mac.

What NOT to do
- Do not buy a locked Mac hoping to unlock it later. There is no later — Activation Lock has no bypass, and Apple will not remove it without proof of original purchase.
- Do not trust 'iCloud unlocked' listings. Software unlocks for Activation Lock are scams — the lock is server-side and unbeatable.
- Do not pay before the check. Money first means leverage lost — the verification happens before payment, always.
- Do not skip the check for 'friends of friends.' Most locked-Mac nightmares start with a trusted introduction and no verification.
Frequently asked questions
Can Apple remove Activation Lock for me?
Only with proof of original purchase from an authorized seller. A secondhand receipt from a stranger does not qualify.
The seller says they forgot their password — help?
They can reset it through Apple's account recovery. If they will not, they are not the owner — walk away.
Is a locked Mac worth anything?
For parts, slightly. As a computer, nothing — you cannot boot past the lock. Price it accordingly, which is to say: don't buy it.
