Apple's macOS Recovery documentation
What Apple's own Recovery articles cover, why the Apple silicon and Intel instructions are separate, and the sentence that protects your files.
This site links to the vendor's own page and hosts no files. Check the hostname before you download anything.
For most Mac reinstalls there is no download and no USB stick. Apple's own Recovery documentation describes how to start from Recovery, what the utilities in that environment do, and how to reinstall the operating system without erasing the disk. It is the first source to open, not the last resort after a tutorial fails.
The documentation is split by processor family and by task. Reading the correct one matters: the key combination that enters Recovery on an Intel Mac does nothing on an Apple silicon Mac, and the words 'reinstall' and 'erase' do not mean what many third-party guides say they mean.
The articles worth keeping open
Apple publishes separate pieces on how to reinstall macOS, on how to create a bootable installer, on Recovery itself and on using Disk Utility. Together they cover the whole path this site describes: decide whether an erase is needed, enter the right Recovery mode, use Disk Utility only if it is, then reinstall.
The reinstall article contains the sentence that matters most to somebody who has not made a backup: reinstalling macOS from Recovery is designed to keep your apps and personal data. It is not a wipe. Older guides that describe it as one have caused people to erase a disk they did not need to erase, and equally have stopped people from doing a repair that was safe.
Reinstall is not erase
Apple's Reinstall macOS option replaces the system and keeps your data. Erase in Disk Utility is the destructive operation. They are separate menu items for a reason.
Apple silicon and Intel: two different first steps
On Apple silicon, shut down, then hold the power button until the startup options screen appears, choose Options and continue. On Intel, power on and immediately hold ⌘R, or ⌥⌘R for internet recovery. Apple's documentation states both explicitly.
The utilities available in Recovery are broadly the same — reinstall, restore from Time Machine, Disk Utility, Safari, Startup Security Utility, Terminal — but authentication and startup security behaviour differ. If Recovery asks for an administrator password, that is FileVault asking to unlock the disk, not a sign that something has gone wrong.
- Apple silicon → hold the power button from a shut-down state → Options.
- Intel → ⌘R at power on, or ⌥⌘R for internet recovery.
- Have the Apple Account password and any FileVault recovery key available.
- Use a reliable network for internet recovery.
When the documentation sends you elsewhere
If the goal is a clean install, Apple's erase-and-reinstall instructions take over and Disk Utility becomes the next step. If the Mac is being sold or given away, a separate article covers signing out of the Apple Account, disabling Find My and leaving the machine at the setup screen — account-level actions that erasing a disk does not perform.
If you need an offline installer or are setting up several machines, the createinstallmedia article is the relevant one. Recovery handles the ordinary case; a bootable installer is the exception, not the default.
How this site uses these sources
The macOS walkthrough on this site follows Apple's sequence and quotes the literal screen labels, but it adds the decision layer that vendor documentation does not: whether a reinstall is proportionate at all, what to test before erasing, and what to do when the same fault returns after setup.
Where the source and a widely copied guide disagree — Secure Boot was the Windows example; SMC and NVRAM resets are the Mac one — the site says so visibly rather than silently correcting. A reader who has already seen the wrong version needs to know which to believe.
Mistakes to avoid
- Reading an Intel-era key combination into an Apple silicon guide and concluding Recovery is broken.
- Believing a third-party page that says reinstalling macOS wipes the disk.
- Erasing in Disk Utility when the actual problem only needed Reinstall macOS.
- Forgetting to sign out of the Apple Account before handing the Mac on.
- Following SMC or NVRAM reset instructions that do not apply to Apple silicon.
Questions people ask
Where do I download macOS?
For a normal reinstall you do not: Recovery downloads what it needs. A full installer from the App Store is only needed for a bootable USB installer.
Which Apple article should I read first?
The reinstall and Recovery articles for your processor family. Move to the Disk Utility instructions only if you have decided to erase.
Does the site mirror Apple's instructions?
No. It links to the vendor's own pages and adds decision guidance around them; the screen labels are quoted so you can find them on your own device.
Why does Recovery need a password?
With FileVault on, the disk must be unlocked before any utility can work with it. Use an administrator password or the recovery key.
