The single biggest reason people put off replacing an aging Mac is the move itself — years of photos, documents, logins, and apps that feel impossible to pack up. Here is the honest truth: Apple has quietly made this one of the easiest transfers in all of computing. Migration Assistant is built into every Mac, it is free, and for most people the whole move takes 30–90 minutes, most of which is waiting while a progress bar does the work. This guide walks through every method step by step, tells you exactly what transfers (and the few things that do not), and covers the snags people actually hit.
Before you start: a 5-minute checklist
- Update the old Mac first. Migration works best when both machines run a recent macOS. If your old Mac is stuck on an ancient version, update it as far as it will go — our macOS compatibility guide shows the ceiling for every model.
- Plug both Macs into power. A transfer that sleeps mid-way is the number-one cause of stalls.
- Know your Apple ID password. You will sign in on the new Mac, and two-factor codes go to your old devices — keep them nearby.
- Optional but faster: a cable. Wi-Fi works fine, but a USB-C or Thunderbolt cable between the two Macs can cut a large transfer from hours to minutes.
- Do not wipe the old Mac yet. Erase it only after you have confirmed everything arrived. (More on selling it below.)
The four ways to move your data
| Method | Best for | Speed | Difficulty |
|---|---|---|---|
| Migration Assistant (Mac to Mac) | Almost everyone — moves apps, files, settings, and user accounts in one pass | Fast (faster with a cable) | Easy — follow the prompts |
| Time Machine backup | When the old Mac is dead, sold, or not with you — restore from the backup drive instead | Fast | Easy |
| iCloud sync | Light users whose life already lives in iCloud Drive, Photos, and Safari | Slow for big photo libraries | Easiest — just sign in |
| Manual copy (external drive) | People who want a fresh start and only need specific folders | Depends on you | Most work — apps must be reinstalled |
For 9 out of 10 people, Migration Assistant is the right answer. It is the only method that brings your applications and settings along instead of just your files.
Method 1: Migration Assistant, step by step
- On the new Mac: during initial setup, Setup Assistant asks if you want to transfer data — say yes. Already past setup? Open Applications > Utilities > Migration Assistant. It works identically either way.
- Choose the source. Select "From a Mac, Time Machine backup, or startup disk."
- On the old Mac: open Migration Assistant there too, and choose "To another Mac." Both machines need to be on the same Wi-Fi network — or connected with a cable.
- Confirm the security code. Both screens show the same number; click Continue on each.
- Pick what to move. Check your user account, Applications, and Other files & folders. If you have multiple user accounts, each one comes across with its own login.
- Wait. The estimate is pessimistic at first — it settles down after a few minutes. Go make coffee; the Macs handle the rest.
- Log in and verify. Your desktop wallpaper, dock layout, browser bookmarks, and files should all be exactly where you left them. It is a genuinely uncanny moment the first time you see it.
Method 2: restoring from a Time Machine backup
If your old Mac already backs up to an external drive with Time Machine, you do not need the old Mac present at all. Plug the backup drive into the new Mac, open Migration Assistant, choose the same "From a Mac, Time Machine backup, or startup disk" option, and select the drive. Everything restores the same way — apps, accounts, settings, files.
No backup yet, but the old Mac still runs? Make one now: plug in any external drive with enough free space, open System Settings > General > Time Machine, add the drive, and let the first backup finish. It doubles as insurance — you get a full snapshot of the old machine before you erase anything.
What transfers — and what does not
- Comes across: your files and folders, photo library, Mail accounts and messages, Safari and Chrome bookmarks and saved passwords (in the keychain), applications, printers, network settings, and system preferences.
- Needs a quick re-login: iCloud, streaming apps, and some banking apps sign you out for security. Your saved passwords come along in the keychain, so this is a two-minute chore, not a disaster.
- May need re-activation: a handful of paid apps with strict licensing (some Adobe and audio software) treat a new Mac as a new install. Deactivate on the old machine first if the app offers it.
- Will not run at all: if you are jumping from an old Intel Mac to Apple Silicon, a few very old 32-bit apps died back in macOS Catalina and cannot follow you. Everything modern runs — often dramatically faster.
How long does it really take?
| Amount of data | Over Wi-Fi | Over a cable |
|---|---|---|
| Under 50GB (light user) | 20–40 min | 10–15 min |
| 50–250GB (typical) | 1–2 hours | 20–45 min |
| 250GB–1TB (photo/video heavy) | 3+ hours | 1–2 hours |
These are real-world figures, not lab numbers. The transfer runs unattended either way — start a big one before dinner and it is done before bed.
Troubleshooting the three common snags
- The transfer looks stuck. The time estimate frequently freezes even while data is moving. Give it 20 minutes before you worry — and never force-restart mid-transfer. If it is genuinely dead, restart both Macs and run it again; Migration Assistant picks a fresh copy, nothing is corrupted.
- The Macs cannot see each other. Put both on the same Wi-Fi network, turn off any VPN, and move them into the same room. Still nothing? A direct USB-C cable sidesteps the network entirely.
- "This version of macOS is too old." Update the old Mac as far as it goes, then retry. If the old Mac cannot update far enough, fall back to the Time Machine method — backups from older macOS versions restore fine onto new ones.
What to do with the old Mac
Once you have confirmed everything arrived — open your photos, check a few documents, log into Mail — the old machine still has real value. Even older and broken Macs are worth store credit toward your next one: see what your old MacBook is worth before it sits in a drawer depreciating. Just erase it first: System Settings > General > Transfer or Reset > Erase All Content and Settings signs out your Apple ID and wipes it clean in one step.
Moving to a refurbished Mac? Same process, smaller bill
Migration Assistant does not care where the destination Mac came from — a refurbished M2 MacBook Air ($549) receives your data exactly like a $1,200 new one, and an M1 Air at $450 does too. Every Mac we ship arrives fully wiped with a fresh macOS install, ready for Setup Assistant to offer you the transfer on first boot. When it arrives, follow our used-MacBook setup walkthrough — Migration Assistant is Step 1.

Frequently asked questions
Do I need any special software or a paid tool?
No. Migration Assistant ships free on every Mac. Third-party "PC mover" utilities are unnecessary for Mac-to-Mac transfers.
Can I use the new Mac while the transfer runs?
If you started it from inside Migration Assistant (after setup), the app takes over the machine until it finishes. Start big transfers when you can leave it alone.
Will my Microsoft Office / Adobe apps come across?
The apps transfer, and Microsoft 365 just asks you to sign back in. Adobe Creative Cloud usually wants a fresh sign-in too, and older perpetual-license Adobe suites may need reactivation.
Does transferring slow down or clutter the new Mac?
No more than the same data cluttered the old one. If your old Mac was slow, that was almost always aging hardware, not your files — the same library on an Apple Silicon Mac feels brand new.
What if my old Mac is completely dead?
If you have a Time Machine backup, restore from that. No backup? A repair shop can often pull the drive contents even from a dead machine — and the dead Mac itself may still have trade-in value for parts.
