Safe mode is a special way of starting an operating system that loads only the minimum drivers and services needed. Windows, macOS and Android each offer a version, usually with a reduced screen resolution or a notice on screen.
Why it matters
When a faulty driver, startup program or malware stops normal startup, safe mode often still boots because the problem component is not loaded. It lets you uninstall recent software, roll back a driver, run a malware scan or use System Restore. If a problem disappears in safe mode, the cause is likely something that does not load there, such as a third-party driver or service.
Example
On Windows 10 or 11, hold Shift while choosing Restart, then pick Troubleshoot, Advanced options, Startup Settings, Restart and press 4 for Safe Mode, or 5 for Safe Mode with Networking. On an Apple silicon Mac, shut down, then hold the power button until startup options appear, select the disk and hold Shift.
Common mistakes
- Staying in safe mode and wondering why Wi-Fi, printing or graphics are limited.
- Forgetting to restart normally after the fix.
- Using it only for malware when it is also good for driver troubleshooting.
