Mac stuck on the Apple logo or a progress bar?

First tell an update from an ordinary startup

An Apple logo means the Mac found a startup disk. A progress bar can appear below it, and the display may go blank and return during startup. The logo alone doesn't identify the part that is failing.

The crucial first detail is whether you just started a macOS update, upgrade or reinstall. Apple's Apple-logo guidance says progress can be much slower then, with long pauses, and recommends starting installation in the evening so it can finish overnight if necessary.

There is no Apple rule that a bar unmoved for a particular number of minutes is safe to interrupt. Keep the charger connected, the lid open and the Mac somewhere ventilated. Watch for actual changes or an error, instead of repeatedly restarting to see whether the bar moves faster.

Power matters during an installation. Apple says a power failure interrupting macOS installation is one rare circumstance that can lead to a firmware problem. That is a reason to avoid casual interruptions, not a claim that every paused update has broken firmware.

Keep your files in view before troubleshooting

The first checks below do not deliberately erase your disk. A forced shutdown can still lose unsaved work, and a disk repair can reveal an existing problem, so your backup situation matters. If this is the only copy of valuable files, stop before any step that says Erase or Restore.

Once the Mac can start again, back it up before further experiments. Recovery's Utilities › Share Disk can also help copy accessible files to another Mac; the Recovery guide explains its limits.

1. Restart once, then test without accessories

After allowing a genuine installation enough time, Apple's stuck-startup checklist begins with turning the Mac off and back on. The power-button steps are the same on Apple silicon under macOS 15 Sequoia, macOS 26 Tahoe and macOS 27 Golden Gate.

1. Force it off if it won't respond. Hold the Mac's power button for up to 10 seconds, until it turns off. On a MacBook with Touch ID, hold the Touch ID button.
2. Start normally. Release, then press and release the button. See the force-restart guide for the data-loss caveat.
3. If the fault remains, shut it off again. Remove nonessential printers, external drives, hubs and other accessories. Keep necessary power, display and input devices attached; don't disconnect the disk you intentionally boot from without selecting another usable startup disk.
4. Start again. If it works, reconnect the optional items one at a time later to identify which device or cable makes the problem return.

If the same startup hang persists without optional devices, don't keep cycling the power. Move to a targeted check.

2. Optionally test safe mode

Safe mode is a useful test if the Mac can reach startup options. It is an additional diagnostic choice; Apple's logo-specific checklist goes from accessories to Recovery disk repair without requiring this step.

On Apple silicon, shut down, hold the power button until startup options appear, select the startup disk, hold Shift and choose Continue in Safe Mode. The detailed safe-mode guide covers the version-specific checks and what its result means.

If safe mode starts, save or back up the needed files, then restart normally with Apple menu › Restart. If the hang returns only in normal mode, investigate login items or software that loads at startup. That result is evidence for further testing, not proof that any particular app is responsible.

If safe mode also fails, or startup options won't appear, follow the Recovery route. For an Intel Mac, use Apple's linked safe-mode instructions; the Apple silicon disk-and-Shift method is different.

3. Repair the startup disk from Recovery

Start macOS Recovery on Apple silicon with Options › Continue from startup options. Select Disk Utility › Continue in its main window. Recovery is separate from the failed ordinary startup.

1. Choose View › Show All Devices if available.
2. Locate the startup storage device. Its volumes, volume groups and containers appear beneath it. Don't choose an unrelated external backup disk because it has a familiar name.
3. Run First Aid from the bottom upward. Begin with the last volume under that device, then work upward through each volume, volume group, container and finally the device. Click First Aid and follow its Run or repair prompt. If unavailable for an item, continue to the next.
4. Read the result. Note unrepaired errors. Quit Disk Utility and restart if repairs complete successfully.

These are Apple's disk-repair instructions. They recommend a current backup in case files are damaged or an error cannot be repaired. If the disk never appears or First Aid cannot repair it, don't silently substitute Erase for First Aid. Contact Apple with the result, particularly if the files aren't backed up.

4. Reinstall macOS without erasing

If repair doesn't resolve the hang, Apple's next logo-specific step is reinstalling macOS from Recovery. Choose Reinstall macOS [name], retain the existing system disk and follow the non-erasing reinstall guide.

Apple says that procedure keeps apps and personal data, while still advising a backup. It doesn't mean an erase is harmless, and it doesn't guarantee recovery from a hardware fault. Leave the Mac powered and allow the new installation to complete.

If the installer errors, keep the wording and check Apple's installation-error checklist. A storage warning, unsuitable network and firmware error need different responses.

When service or firmware repair is next

Apple says a Mac that continues to stop at the logo or progress bar may need service. If Recovery won't start, the display shows an exclamation mark in a circle, or an installation fails despite the earlier checks, read Apple's firmware-repair page or contact Support.

Its current instructions use another Mac running macOS 14 or later and a suitable cable and port. Revive attempts to repair firmware without erasing; Restore erases and returns the Mac to factory settings. Don't treat the two buttons as interchangeable.

You don't need to decide on an erase merely to ask for help. State the model, the last successful macOS version, whether the problem followed an update, the screens reached and the backup situation. Stop repeating forced starts when the same result is all you learn.

Where Tend fits

Tend can't help while the Mac won't start. After macOS is working, its free Startup Items view lets you switch optional helpers off and back on when investigating a hang after login; it doesn't repair the startup disk or firmware.
