How to Start Your Mac in Safe Mode
This wikiHow teaches you how to restart your Mac into Safe Mode. Safe Mode is a diagnostic tool that disables non-essential programs and services on your Mac, thus allowing you to remove troublesome programs or change persistent settings.
Steps
-
Prompt your Mac to restart. If your Mac is currently on, you'll need to begin restarting it before you can access Safe Mode. Click the Apple menu , click Restart..., and click Restart when prompted.
- If your Mac is already off, press the "Power" {"smallUrl":"https:\/\/www.wikihow.com\/images\/5\/5d\/Windowspower.png","bigUrl":"\/images\/thumb\/5\/5d\/Windowspower.png\/30px-Windowspower.png","smallWidth":460,"smallHeight":460,"bigWidth":30,"bigHeight":30,"licensing":"<div class=\"mw-parser-output\"><p>I edited this screenshot of a Windows icon.\n<\/p><p>License: <a target=\"_blank\" rel=\"nofollow noreferrer noopener\" class=\"external text\" href=\"http:\/\/en.wikipedia.org\/wiki\/Public_domain\">Public Domain<\/a><br>\n<\/p><\/div>"} key or button to begin starting up your Mac.
-
Press and hold the ⇧ Shift key. As soon as your Mac begins restarting, hold down the ⇧ Shift key and don't let go.
- If you're using a Bluetooth keyboard, make sure you press ⇧ Shift after the boot-up sound (or directly after the Apple logo appears).
-
Wait for the login screen to appear. This screen will pop up after a minute or two.
-
Release the ⇧ Shift key. Once the login screen appears, your Mac should be in Safe Mode, meaning you can release the ⇧ Shift key.
-
Log into your Mac. Select your user account, then enter your account password to do so.
- If your Mac has FileVault enabled, you'll first need to log in to unlock your Mac's startup disk.
-
Troubleshoot program problems. If you've been having an issue with your Mac's startup sequence or general operation, look to see if the problem persists while in Safe Mode; if it doesn't, one of your Mac's programs is probably at fault.
- Unfortunately, if the problem is still present, your Mac's base hardware or software is causing the issue.
-
Disable startup programs. While you're in Safe Mode, remove any problematic or resource-heavy programs from your list of startup items. This will help your Mac boot up faster.
- You can also remove problematic applications, such as third-party antivirus suites or stubborn programs, in Safe Mode.
-
Restart your Mac to exit Safe Mode. When you're done using Safe Mode on your Mac, click the Apple menu and click Restart..., then follow any on-screen prompts. Your Mac will restart into its regular mode.
Tips
- In some cases, you can also activate Safe Mode by typing sudo nvram boot-args="-x" into Terminal and pressing ⏎ Return. You can then disable Safe Mode by typing in sudo nvram boot-args="-x -v" and pressing ⏎ Return. This won't work if you have FileVault enabled on your Mac.
Warnings
- You won't be able to use some programs and features while in Safe Mode.
