📋 Step-by-Step Guide (5 Steps)
Perform a Hard Shutdown and Connect Wall Power
Press and hold the Mac's physical power button or Touch ID sensor for a full 10 seconds until the screen goes completely dark. Connect the official MagSafe or USB-C charging cable and verify the charging indicator illuminates or screen backlight turns off.
- • Screen is completely pitch black with no backlight visible.
- • Charging cable is firmly seated in the port with green/amber light or power connected.
- • Releasing the power button too early before the system fully powers down.
- • Attempting system repair on weak battery power.
Boot into macOS Recovery Mode
For Apple Silicon (M1/M2/M3), press and hold the power button until 'Loading startup options' appears. For Intel Macs, press the power button once, then immediately press and hold Command (⌘) and R together until the Apple logo or spinning globe appears.
- • Screen displays the macOS Utilities window with 4 distinct menu options or an 'Options' gear icon.
- • Pressing Command + R too late after hearing the startup chime on Intel Macs.
- • Tapping the power button quickly instead of holding it down on Apple Silicon models.
Launch Disk Utility and Inspect Drives
From the macOS Utilities list, click 'Disk Utility' and choose 'Continue'. In the top menu bar or toolbar, click 'View' and select 'Show All Devices' to reveal physical drives and parent containers in the left sidebar.
- • Disk Utility window is open showing an hierarchical sidebar list of internal disks (e.g., Apple SSD, Macintosh HD).
- • Leaving the view set to 'Show Only Volumes', hiding container corruption issues.
Run First Aid on Drive Volumes and Containers
Select the lowest volume under your internal disk (usually 'Macintosh HD - Data' or 'Macintosh HD') and click the 'First Aid' button at the top, then click 'Run'. Once finished, repeat First Aid upward on the container, and finally on the top-level disk itself.
- • Progress bar runs and completes with a green checkmark stating 'Operation successful' or 'The volume appears to be OK'.
- • Running First Aid only once on the top drive instead of starting from the lowest child volume.
- • Closing Disk Utility before the operation finishes.
Select Startup Disk and Reboot System
Close Disk Utility by clicking the red traffic light button. Click the Apple menu () in the top-left corner, select 'Startup Disk', click your primary system drive (e.g., 'Macintosh HD macOS'), and click 'Restart'.
- • The Mac screen restarts, shows the Apple logo with a solid loading progress bar, and loads into the standard user login screen.
- • Simply restarting without explicitly designating the startup volume in the menu.
- • Selecting an external installer drive instead of the internal boot volume.
