Hull iMac and MacBook recovery. A question mark means no system found — your files are a separate question.

A Mac that will not start tells you very little. A question mark means it found no system at all; a circle with a line through it means it found one and would not run it; a bar that stops halfway is a third thing again. None of them says whether your files can be read. What settles that is which machine you have. An older iMac holds a disk that comes out. A Fusion iMac holds two, working as one. A MacBook Pro from 2016 on has its flash soldered down, and from 2018 the keys sit in the chip. Leave it off until you know which one you are dealing with, wherever in Hull it is sitting.

Why the Mac model matters more than the symptom.

The model decides the jobWhich Mac you have settles most of it before the box is opened. A 2011 iMac hands you a 3.5in disk. A 2015 MacBook Pro hands you a blade in a slot. A 2019 one hands you a soldered chip and a board there is no way around. What the screen shows matters a good deal less than that.
SATA, blade SSD, solderedMacBook Pros up to 2012 carry a 2.5in SATA disk you can lift straight out. From late 2012 to 2015 it is an Apple blade in a slot, readable on an adapter. From 2016 most of them have the flash soldered on, so those come in as complete machines.
What a Fusion Drive isAn SSD and a hard disk that macOS presents as one volume, with the busy files kept on the quick half. Apple fitted them to iMacs through most of the 2010s. One volume over two devices means one failing device stops the lot, and a file can straddle both.
Things we will not do to itNo reinstall, no Erase Mac, no First Aid against the disk you posted. All three write to the container, and it is writing that closes the door. Your disk is read once and then set aside; the repair work happens on the image, where a mistake costs nothing.

01

A case number first, then a free diagnosis Free

Each item that arrives gets a case number the day it lands. An engineer looks at it and finds the real fault, and that costs you nothing. You are told in plain terms which files can come off the drive and which cannot. A price follows — one figure, written down. No work starts until you have seen it and agreed to it.

The diagnosis is freeOne price, put in writingNothing to pay yet
02

An image first, your disk untouched

The disk is read on our own hardware behind a write blocker, and a sector-by-sector image is taken before any file is opened. A Fusion pair gets two images, one for each half. Weak areas are worked in passes. Nothing goes back onto what you sent.

Each disk clonedNothing written to it

Reading what the Mac would not

After that the original is put away and everything happens on the image. The APFS container is examined, the volume group is put back together, the map that ties the two Fusion halves is rebuilt, FileVault is opened with your password, and the volume is mounted read-only.

Repairs stay on the image

A container that has come apart, a volume that will not mount, a home folder that refuses to open — each is dealt with on the image and never on your disk. Then every file is opened in turn, so what reaches the listing is what actually works.

You sign it off, then it comes back

You are not billed while you are still thinking. The list of what came off the drive goes to you first, and the invoice waits on your word. Files go home on media bought in for the job, with the postage back on us. We keep the job open until you have opened them on your own machine.

What turns up most often

  • The screen is not a diagnosis — a question mark sits equally well on a dead disk, on a container that has come apart, and on a Fusion pair the Mac can no longer join up. Only reading the disk will separate them.
  • Recovery mode holds nothing of yours — it is a small system for reinstalling macOS and it fetches the rest from Apple. A reinstall puts a fresh copy into the container your files live in, and Erase Mac empties that container on purpose.
  • A dead-looking Mac is often a healthy one — plenty arrive with sound flash sitting behind nothing worse than a broken system volume. The disk is imaged, the data volume is mounted on other hardware, and the files come off without any argument.
  • Modern Macs are encrypted whether you asked or not — from the T2 onward the flash is tied to the one logic board it is soldered to, and Apple silicon keeps the keys inside the SoC. A dead board ends it, here and in any other lab. A live one needs the password.

What decides these jobs: which Mac it is, whether the board still works, whether you have the password, and whether anyone has reinstalled since. An older iMac with a failing disk, left switched off, is a good position. The same iMac after a reinstall, a First Aid run and a night of restarts is a shorter list. On a T2 or M-series machine, the board is the whole question.

An iMac that slowed all summer, then would not get past the logo

It came from a design studio in the Fruit Market: a 27in iMac that had been getting slower since about May, then stopped starting altogether. A repair counter had told them the machine was finished. Inside was a Fusion Drive — a 128GB blade and a 2TB hard disk that macOS shows you as one volume. The blade read clean. The hard disk had a band of weak sectors through the middle of it, which is why the pair would no longer mount. Each half was imaged on its own, the slow one over several passes, and the mapping that joins them was rebuilt from those images. FileVault opened with the password written on the form. The files went back on a new drive and the tender went out on the Friday.

Both Fusion halves read2 days to the deadline

Before you box it up.

Do these first

  • Shut it down as soon as it stops starting up
  • Write down the model and year of the Mac
  • Dig out the FileVault password or recovery key
  • Send an iMac whole, screen and stand included

What not to do

  • Reinstall macOS to see whether that fixes it
  • Run First Aid on the disk you want back
  • Keep restarting in the hope it catches
  • Prise the display off an iMac on the kitchen table

Asked most weeks, answered here.

A flashing question mark — has the disk gone?

Usually not. That folder means the Mac looked for a system to start and found none it would accept. The disk underneath is often sound, and so are the files on it. What has gone is the startup path — a container that has come apart, a missing volume, or a Fusion pair the Mac can no longer join up. Leave it switched off.

My iMac's Fusion Drive will not mount. Is it both disks?

Rarely. One half is usually the trouble, and on an iMac it is nearly always the spinning one. But a Fusion Drive is a single volume laid across an SSD and a hard disk, so a file can begin on one and end on the other. Take the failing half out on its own and you are left with pieces. Both halves get imaged, then the map between them is rebuilt.

Should I reinstall macOS to get the files back?

Please do not. A reinstall writes a fresh system into the same container your files are sitting in, and on an APFS volume group it can take the snapshots with it. Erase Mac in Recovery is worse again, and on Apple silicon a Restore in Apple Configurator empties the flash outright. If you want the Mac usable afterwards, say so — the files come off first and the rebuild follows.

FileVault wants a password nobody has. What now?

Find it before you post anything. The password of an account that could log in will do, or the 24-character recovery key, or the key you escrowed with iCloud. A T2 or Apple silicon Mac encrypts its flash to that one logic board whether FileVault is on or not, so the machine has to arrive whole and working. Without a password, a perfect image of it reads as noise.

A drive left switched off loses nothing more.

Leave it switched off. A failing drive has a limited number of starts in it, and each one spends a little more. The free diagnosis will say which files can be read.
