What is Safe Mode and How to start your Mac in Safe Mode

What is Safe Mode and How to start your Mac in Safe Mode


You can use safe mode to help you resolve issues that might keep your Mac from completely starting up.

What is safe mode?

Safe mode (sometimes called safe boot) is a way to start up your Mac so that it performs certain checks, and prevents some software from automatically loading or opening. Starting your Mac in safe mode does the following:


  • Verifies your startup disk, and attempts to repair directory issues if needed
  • Only essential kernel extensions are loaded- (a.k.a. ketxs, or hardware and software drivers), No third party items 
  • Prevents Startup Items and Login Items from opening automatically
  • Disables user-installed fonts 
  • Deletes font caches, Kernel cache and other system cache files
  • Together, these changes can help resolve or isolate issues related to your startup disk. 

And its very simple to start your Mac in Safe Mode, either using your keyboard or by entering a command in Terminal.We will learn different way of starting your Mac in Safe Mode later in this post.

When and why should we start Mac in Safe Mode?

When you have some problem with your mac the first troubleshooting you do is restart the Mac.
Most of the time, your Mac just works after restarting.

But there will be times when a rogue app, a misbehaving service, outdated caches and other issue will cause your Mac to slow, stop starting up or exhibit other unwanted symptoms. Thankfully, Apple has provided a way to boot OS X in Safe Mode.

Although booting in Safe Mode on a daily basis?or whenever an insignificant problem arises? isn?t recommended, there are definitely instances when starting up in Safe Mode could be your last resort.

Here are some of the typical scenarios:

If your Mac doesn?t finish starting up?Certain issues might keep your Mac from completely starting up and using Safe Mode can help you resolve them.

If an app is causing issues? An app you recently installed might be the culprit, especially if it came outside the Mac App Store. Starting up in Safe Mode might help isolate the misbehaving app as it prevents certain software from automatically loading or opening.

If your Mac is running slow? Just like Windows, your Mac also creates temporary files and various caches over time which might slow down the overall performance of the operating system and apps. These unnecessary files are safely cleaned from Mac when started in safe Mode.

If your Mac has directory issues?Many, but not all issues with your Mac?s startup disk can be resolved using the built-in Disk Utility application. If you?re plagued with an issue that cannot be reproduced in Safe Mode but appears to be resolved when you start up normally, chances are it was caused by a cache or a directory issue with your startup disk that Safe Mode fixed.

How to Start your Mac in Safe Mode?

Starting up in safe mode

  1. Follow these steps to start up into safe mode.
  2. Start or restart your Mac. 
  3. Immediately after you hear the startup sound, press and hold the Shift key.( Note:- If you are using a Wireless Keyboard,Make sure you press the Shift Key immediately after you hear the start up chimes sound.Bluetooth controllers will only activate after the startup chimes sound, so if the key is held before this, the key press will not be recognized. ).
  4. Release the Shift key when you see the Apple logo appear on the screen.
  5. Start your Mac in Safe Mode
    Start your Mac in Safe Mode
  6. After the Apple logo appears, it might take longer than usual to reach the login screen or your desktop. This is because your Mac performs a directory check of your startup disk as part of safe mode.
  7. Start your Mac in Safe Mode
    Start your Mac in Safe Mode
  8. To leave safe mode, restart your computer without pressing any keys during startup.

If youre using FileVault

If your startup disk is encrypted with FileVault, you can still hold down the Shift key immediately after powering on your Mac to start up in safe mode. You might be prompted to log in twice as part of this process ? first to unlock the startup disk, and a second time to log into the Finder. You can let go of the Shift key after you see the first login screen.


If an issue doesnt happen in safe mode

If an issue doesnt happen when your Mac is started in safe mode, try restarting again without pressing any keys at startup. If the issue appears to be resolved when you start up normally, it was possibly caused by a cache or a directory issue with your startup disk that safe mode fixed.
If you restart your Mac normally and an issue comes back when you reach your desktop, try disabling any login items that automatically open when you log in.

If your Mac restarts or shuts down in safe mode

If your Mac automatically restarts in safe mode, OS X might have found an issue that its trying to fix. 
Safe mode performs a directory check of your startup disk, similar to what happens when you choose to verify or repair a disk using Disk Utility. If OS X finds an issue, the directory on your startup disk is repaired and your Mac restarts. 
If your Mac turns itself off when you start up in safe mode, check the power connection on your Mac to make sure its plugged in securely at both your Mac and the power outlet. If youre using a MagSafe power adapter, make sure the LED on your power adapter is yellow or green. Then, try starting up in safe mode again.

If your Mac repeatedly restarts or shuts down during safe mode, contact Apple Support, or consult with an Apple Authorized Service Provider or Apple Genius for more help.


Is your Mac taking longer than usual to boot in Safe Mode?


This is normal.Your Mac performs a directory check of your startup disk as part of Safe Mode so it will take a significantly longer time than usual to reach the login screen or the desktop


3 ways of identifying if you?re started in Safe Mode

If you?re unsure as to whether or not you?re in Safe Mode, take note of the following signs that give it away.

1. Menu bar reads ?Safe Boot?

Start your Mac in Safe Mode
Start your Mac in Safe Mode

The first indication that you?re starting up in Safe Mode appears when you land on the login screen. If you?re in Safe Mode, the words ?Safe Boot? in red letters will appear in the menu bar in the upper right corner of the screen.


2. Slower overall performance

Past the login screen, you?ll notice slower overall performance. Graphics will no longer be accelerated as default drivers are loaded. The OS X menus, windows and the Dock appear solid even if Translucent Menu Bar is selected in System Preferences.

Your screen might blink or tear during the login process. OS X menus, the Dock, your desktop and other aspects of the user interface won?t have as many visual effects and translucency will be disabled.

And as mentioned further below, several OS X features might be unavailable to you in Safe Mode, like watching movies in the DVD Player app, capturing video, connecting to Wi-Fi networks and more.

3. Boot Mode in System Information reads ?Safe?

Another method of determining the status of your boot mode involves using the System Information application.

Step 1: Open System Information from Applications > Utilities. You can also choose About This Mac from the Apple menu and then click the System Report button in the Overview section.

Step 2: In the lefthand column, locate and click the Software section. You should see a couple related items listed on the right side of the System Information window.

If the Boot Mode is listed as ?Safe? you?re started in Safe Mode. If it reads ?Normal,? you?re in OS X?s normal-boot mode.


Some features arent available in safe mode

Some features of your Mac arent available when its started in safe mode, so after youre done using safe mode you should restart your computer normally.

For example, these features dont work in safe mode:

  • You cant play movies in DVD Player.
  • You cant capture video in iMovie and some other video apps.
  • Some audio input or output devices might not work.
  • Some USB, FireWire and Thunderbolt devices might not be available.
  • Wi-Fi networking might be limited or unavailable depending on the Mac and OS X version youre using.
Safe mode in OS X v10.5 or later also disables accelerated graphics. This makes the OS X menu bar appear solid even if "Translucent Menu Bar" is selected in System Preferences. Your screen might also "blink" or "tear" during login when your Mac is started in safe mode.

Safe mode in OS X v10.6 or later also disables File Sharing.


Starting in safe mode without a keyboard

If your Mac doesnt have a keyboard available to start in safe mode but you have remote access to it, you can configure the Mac to startup in safe mode using the command line.
Access the command line by either opening Terminal remotely, or by logging into the computer using SSH.

Use the following Terminal command and restart your Mac:

sudo nvram boot-args="-x"

Start your Mac in Safe Mode
Start your Mac in Safe Mode


Unfortunately it is a bit difficult to see if this is the case when the system is only displaying a gray progress bar; however, you can force the system to show you what is going on by having it boot to both Safe and Verbose modes at the same time.If you want to start in verbose mode as well, use this instead:

sudo nvram boot-args="-x -v"

To restart your Mac normally from Safe Mode.After using safe mode, use this Terminal command to return to a normal startup:

sudo nvram boot-args=""

Start your Mac in Safe Mode
Start your Mac in Safe Mode

Note :- You can replace the "v" with an "s" to tell it to use "Single User mode" instead (they should be equivalent for this purpose):

sudo nvram boot-args="-x -s"

TP Link Recovery Mode for WR1043ND

TP Link Recovery Mode for WR1043ND


Did I ever mentioned that my overclocked bootloader has TP-Links new built in tftp recovery mechanism?
Do know know if you ever flashed my overclocked bootloader successfully and later "brick" it by flashing new OpenWRT images wrongly there is a 100% chance of recovery?

Simply said I created the overclocked firmware mods by detecting the bit responsible for flipping up the PLL, modifying the bit and correcting the checksum so the new TP-Link uboot tftp recovery mechanism still works.

In fact I use it to test all the firmware I built ALL THE TIME because I am simply too lazy to open up the router and connect the serial pins.

So how do you do it?
  1. Turn off all firewall
  2. Get a tftp server software, in Windows I use tftpd32 in Linux I use dnsmasq
  3. Copy a factory firmware (without the uboot) into the tftp directory change the filename to wr1043nv1_tp_recovery.bin
  4. To activate the recovery mode hold the reset button immediately when it powers on before it boots into linux, you will flashing lights.
  5. This emergency mode listens for the IP Address 192.168.0.66 so you can set 192.168.0.66 static ip mode on your PC running the tftp software
  6. After that if the router detects the tftp server it will attempt to grab to grab the file wr1043nv1_tp_recovery.bin from the tftp server at 192.168.0.66
  7. Then it will begin flashing itself you just need to grab a cup of coffee while it reboots after flashing
In fact all new TP-Link firmware with bootloaders now come with recovery modes listening at different address. You can refer to this useful forum thread by a uboot expert pepe2k.
