My Mac stopped booting after a recent crash, and I need to recover important files from the hard drive without taking it to a shop if possible. I’m looking for safe at-home Mac hard drive data recovery steps or tools that won’t risk overwriting anything.
First thing: stop using that drive as much as you can. That matters more than which recovery app you pick.
Deleted files on macOS usually are not wiped out instantly. A lot of the time, the system just marks that space as free, and the actual data sits there until something else gets written over it. So if this is an external drive, unplug it for now. If it is your Mac’s internal drive, avoid downloading things, installing apps, copying files, or doing anything heavy until you’ve checked your recovery options.
Also, don’t skip the boring checks. They sometimes work.
Open the Trash first. If the missing files were on an external drive, plug it in, open it in Finder, and press Shift + Command + Period to show hidden files. Look for a folder called .Trashes. If the files are sitting there, right-click them and choose “Put Back.”
Then check Time Machine, assuming it was already turned on before the files vanished. Open Time Machine from the menu bar, go back to a point where the files still existed, select them, and hit “Restore.”
If there’s no backup and the Trash is empty, then recovery software is the next realistic option. Something like Disk Drill can scan Mac drives formatted as APFS or HFS+ and may still find files even if the original folders or filenames are gone.
The deeper scans usually work by looking for file patterns, not just the file directory. That’s how they can sometimes recover photos, videos, documents, archives, and other file types even after Finder no longer sees them. If the drive is acting flaky, taking forever, or disconnecting on its own, make a byte-for-byte image first and scan that instead. It puts less stress on the original drive.
Internal SSDs are trickier. Because of TRIM, deleted blocks may get cleared automatically, and once that happens, recovery software probably won’t bring them back. That’s another reason to keep drive activity to a minimum right away.
If the drive is making clicking, grinding, repeated spin-up sounds, or any other weird mechanical noises, don’t run recovery software on it. Unplug it. Software can’t fix physical damage, and scanning may make things worse. If the files are worth the money, that’s when a professional recovery service makes more sense.
Once you get through this, set up more than one backup. Time Machine is fine for a local copy, and a trusted cloud backup gives you another layer. For now, the safest order is: stop writing to the drive, check Trash and Time Machine, then recover from another drive or from a disk image if needed.

A Mac that will not boot is a different problem from a Mac drive that is actually dying. If the crash only broke macOS, the files may be perfectly readable from another startup disk. If the drive itself is failing, every extra scan or boot attempt can make recovery harder.
Before buying recovery software, I’d try getting the Mac mounted from the outside. On Intel Macs, Target Disk Mode can sometimes let another Mac see it like an external drive. On newer Apple silicon Macs, you’re looking at Share Disk from macOS Recovery instead. Either way, you’ll need the FileVault/admin password if the drive is encrypted. If it mounts, copy the important folders first: Desktop, Documents, Pictures, any work folders, then worry about the rest later. Don’t reinstall macOS onto the same drive just to “fix” it unless you already have the files off.
I agree with the earlier warning about not writing to the disk, but I’d be more skeptical of running a full deep scan immediately. If Finder or Disk Utility can see the volume, grab what you can with normal copying first. If it won’t mount, then Disk Drill or similar recovery software makes sense, preferably from another Mac and saving recovered files to a separate external drive. The annoying catch is encryption: if the APFS container is damaged and FileVault can’t unlock, home recovery gets limited fast, even if the hardware is fine.
A Mac that still powers on and reaches Recovery is a very different job from a Mac that is completely dead and shows no sign of life. In the first case, you may still have several home options. In the second case, especially on newer Macs with soldered storage, there may be no “pull the drive and plug it into a dock” path at all.
That is the annoying detail people often miss with Macs. Older MacBooks and iMacs with removable SATA drives are pretty friendly for DIY recovery. You can remove the drive, put it in a USB enclosure, and copy files from another Mac. But a lot of newer Macs use soldered SSD storage, and on T2/Apple silicon models the storage is tied into the security hardware. If the logic board is dead, home recovery can hit a wall fast even if the actual data chips are fine.
If the Mac does turn on, I would try the lowest-impact route first:
- Boot to macOS Recovery.
- Open Disk Utility.
- See whether the internal volume appears.
- If it appears but is locked, try unlocking it with the admin/FileVault password.
- If it mounts, copy files to an external drive from Finder or Terminal before trying repairs.
I would be careful with Disk Utility First Aid at this stage. It is useful, but it is still a repair operation, not a pure copy operation. If the directory structure is already damaged, repair attempts can sometimes make the next recovery attempt messier. I would only run repairs after I had copied the important folders or after I had accepted that normal copying is not going to work.
A practical trick if Finder is being flaky is to use Terminal from Recovery. You can sometimes copy files with cp or rsync even when the normal desktop is acting weird. It is not pretty, but it avoids booting the broken macOS install. You need an external drive formatted in a way the Mac can write to, preferably APFS or exFAT if you need compatibility. Don’t save recovered files back onto the internal drive.
If the drive mounts but copying stops on certain files, don’t keep hammering the same folder. Skip it and get the irreplaceable stuff first. Photos, tax files, work documents, project folders, password vault exports, whatever matters most. People lose time trying to rescue a giant Movies folder while the drive is getting worse.
Recovery apps like Disk Drill have their place, but I would treat them as step two, not step one. They are more useful when the volume will not mount correctly, files were deleted, or the directory is damaged. If you use one, run it from another boot drive or another Mac, and recover onto a separate external disk. Installing recovery software onto the same internal drive you are trying to recover from is exactly the kind of thing that can overwrite what you want back.
The other hidden problem is space. If you have a 1 TB internal drive, don’t start this with a half-full 500 GB external drive and hope it works out. You may need enough room for a disk image plus recovered files. A byte-for-byte image is often the safer thing to scan, but it can be large, slow, and boring. Still better than repeatedly scanning a questionable drive.
For a Mac that will not boot but does power on, I would try in this order: Recovery, external boot disk, Target Disk Mode or Share Disk if supported, then recovery software from a separate system. For a Mac that will not power on at all, the DIY options depend heavily on the model year. If it has a removable SSD or hard drive, you may be able to use an enclosure. If it is a newer soldered-storage Mac, there may not be a clean at-home route.
And if this was a hard crash followed by no boot, don’t assume the files are gone. A broken macOS install, failed update, or corrupted system volume can look scary while the user data is still sitting there. The main thing is to avoid turning a recoverable software problem into an overwrite problem by reinstalling, erasing, or “trying stuff” on the same disk.
Whether Desktop and Documents were syncing to iCloud matters before you start poking at the drive. Check iCloud.com, Dropbox, Google Drive, etc. from another computer first, because if the important files are already there, you can avoid stressing a possibly failing disk at all.
