Yes, you can often recover data from a Mac after a factory reset, but success depends entirely on what you did after the reset. If you reset the Mac and then immediately stopped using it, your files may still be intact and recoverable with the right software. If you have already installed macOS, signed in, and copied new files over the old data, recovery becomes much harder — sometimes impossible.
What a Factory Reset Actually Does to Your Data
A factory reset on a Mac (using macOS Recovery or the “Erase All Content and Settings� option in System Settings) does two things: it deletes the encryption keys that scramble your data, and it removes the file system structure that points to your files. On modern Macs with the T2 security chip or Apple Silicon, the built-in SSD is hardware-encrypted. When you erase the disk, macOS discards the encryption keys, making the data appear as random noise. Until those key blocks are overwritten, the raw data still sits on the flash storage, but it is unreadable without the original keys. On older Macs without hardware encryption, a factory reset simply marks the old file system blocks as free, so the actual file contents remain on the drive until overwritten.
Why You Might Still Be Able to Recover Files
Recovery is possible because “erasing� a disk does not physically destroy the data. The operating system only removes the index of where files are stored. The underlying 1s and 0s remain on the flash memory or hard drive until new data is written over them. If you reset the Mac and then did nothing — no reinstall, no login, no file copying — the old data is still there, just hidden. Data recovery software can scan the raw sectors and rebuild the file system structure from the remnants.
How to Recover Data After a Factory Reset (Step-by-Step)
If you have already reset the Mac and want to try recovery, follow these steps immediately. The less you use the Mac, the better your chances.
- Stop using the Mac right now. Do not install macOS, do not open apps, do not copy files. Every new write to the disk can overwrite the exact sectors that hold your old files.
- Get a second storage device. You will need an external drive or a large USB stick to save the recovered files. Never save recovered files to the same disk you are recovering from.
- Download data recovery software on another computer. If you have a second Mac or PC, download a reputable recovery tool. If you only have the reset Mac, you can boot into macOS Recovery and use Safari to download the software, but that writes to the disk — so weigh the risk.
- Boot the Mac in Target Disk Mode or use a recovery boot drive. If you have another Mac, you can connect the reset Mac via Thunderbolt or USB-C and boot it in Target Disk Mode (hold T at startup). That turns the reset Mac into an external drive for the other Mac, so the recovery software runs from the other machine and never writes to the reset disk.
- Run the recovery scan. Choose the “deep scan� or “raw recovery� option. This reads every sector of the drive and tries to identify file signatures (like JPEG headers or PDF magic numbers) even if the file system is gone.
- Recover to the external drive. Select the files you need and save them to the external storage. Do not save them back to the Mac until you are sure you have everything.
Best Data Recovery Software for Mac
Several reliable tools can scan a wiped Mac drive. Most offer a free trial that lets you see what files are recoverable before you pay. Here are the most commonly used options:
- Disk Drill — Supports APFS and HFS+, has a “Recovery Vault� feature, and offers a free trial with preview.
- Data Rescue — A long-standing Mac tool with both quick and deep scan modes.
- EaseUS Data Recovery Wizard — Works on both Mac and Windows, supports APFS, and has a straightforward interface.
- Stellar Data Recovery — Offers a Mac-specific version and can recover from formatted or erased drives.
- TestDisk — A free, open-source command-line tool that can rebuild partition tables. It is powerful but not beginner-friendly.
When choosing software, look for one that explicitly supports APFS (Apple File System) and the macOS version you were using. Some older tools only read HFS+, so they may miss files on modern Macs.
When Recovery Is Impossible (or Nearly So)
There are three situations where you likely cannot get your files back:
- You used FileVault and erased the disk. FileVault encrypts the entire drive. When you reset, macOS deletes the encryption keys. Without those keys, the data is mathematically unreadable — even with the most advanced recovery tools. There is no workaround.
- You reinstalled macOS and used the Mac for hours or days. The new system, apps, and your own new files have overwritten the old data. Flash memory wears leveling also moves data around, so even sectors you think are untouched may have been rewritten.
- The Mac uses Apple Silicon or a T2 chip and you ran “Erase All Content and Settings.� This feature is designed to cryptographically wipe the SSD by destroying the encryption keys. It is effectively a secure erase, and recovery is not feasible.
How to Avoid This Next Time: Backup Options
The only reliable way to protect your data is to back it up before you reset. macOS includes several built-in options:
- Time Machine — Automatically backs up to an external drive or network share. You can restore the entire system or individual files.
- iCloud Drive — Syncs Documents, Desktop, and other folders to Apple’s cloud. After a reset, you can sign in and download your files.
- Clone with Disk Utility — Create a bootable copy of your entire Mac on an external drive using the “Restore� tab. This gives you a full, bootable backup.
If you are planning to sell or give away your Mac, a factory reset is the right final step — but only after you have verified your backups. For a Mac you plan to keep, a reset should be a last resort, not a routine cleanup.
Frequently Asked Questions
Can I recover data from a Mac that has been reset and reinstalled?
Possibly, but only if the reinstall did not overwrite the old data. If you reinstalled macOS and then used the Mac for a while, the new files have likely overwritten the old ones. Run a deep scan with recovery software to see what remains. The sooner you try, the better.
Does FileVault make recovery impossible after a factory reset?
Yes. FileVault encrypts the entire drive, and a factory reset destroys the encryption keys. Without the keys, the data is unreadable, even with professional recovery tools. If you had FileVault on and did not disable it before the reset, your files are gone.
How much does Mac data recovery cost?
Software licenses typically range from $40 to $100. Professional recovery services that physically open the drive and read the chips can cost hundreds to thousands of dollars, and they still cannot recover data after a cryptographic wipe. For most users, trying software first is the sensible approach.
Can I recover data from a Mac that won’t boot after the reset?
Yes, if the drive itself is still functional. You can remove the SSD (on older Macs) and connect it to another computer using a USB enclosure, or use Target Disk Mode on Macs that support it. Then run recovery software from the other machine.
Is it possible to recover data after using “Erase All Content and Settings� on an Apple Silicon Mac?
No. That feature performs a cryptographic erase by discarding the volume encryption keys. The data is rendered unrecoverable by design. This is different from a simple format, which only removes the file system pointers.
What should I do immediately after a factory reset to maximize recovery chances?
Stop using the Mac. Do not install macOS, do not log in, do not connect to Wi-Fi. Connect the Mac to another computer via Target Disk Mode and scan the drive with recovery software. Every minute you use the Mac reduces the chance of recovery.
