MacBook Intake
Steps

4. Enter Recovery

Cmd+R on Intel, power-hold on Apple Silicon — timing matters on both.

Turn the Mac on (or restart it) and immediately press and hold Command (⌘) + R — start holding right after pressing power, before or during the startup chime, not after the screen lights up.

Keep holding both keys until the Apple logo or a spinning globe appears, then release. Don't let go at the chime — too early and it boots normally.

Wait for the macOS Utilities window to load.

Related combinations, held the exact same way — press immediately, release at the Apple logo/globe:

KeysWhat you get
⌘RBuilt-in Recovery; the latest macOS that was installed on this Mac
⌥⌘RInternet Recovery; upgrades to the latest macOS this Mac supports
⇧⌥⌘RInternet Recovery; the macOS the Mac shipped with (or closest still available)
⌥Startup Manager, the boot-device picker — see Step 5

If a padlock prompt appears instead of the Apple logo, that's a firmware password — go to Step 3.
