Reset OS X to factory settings. How to reset the poppy to the factory state. Reset MacBook Settings

Acquaintance with the article Material will help to figure out when (and how) need to reset SMC - settings for the controller controller of the McBook system built on the Intel processors. Meeting of the article will help to figure out when (and how) need to dump SMC - Macbook settings built on Intel processors .

Reset the McBook System Management Setup is reasonable only when any other device setup methods do not help eliminate malfunction.

If the changes in the device does not notice (defects are relevant), it remains only to reset SMC.

Sequence of action to SMC reset

  1. Use the combination of the "Command-Option-Escape" buttons to enforce the completion of the "dependent" application.
  2. Select the "Sleep" mode in the Apple menu and activate it. Wake out for a while (10-15 minutes), then bring MacBook from the "Sleep" mode.

  3. Reload the computer in each case of a power outage case.

Only after the production of all these actions in the specified sequenceit is permissible to proceed to the SMC setpoint reset process, when none of the steps have led to correcting the problem.

SMC settings in MacBooks


To reset system settings, it suffices to use a specific key combination

First, it is necessary to determine the battery installation configuration in the machine. There are two configuration options: the battery is removable and mounted into the case. If the battery disassembly is supported, then:

  1. Disable the charging module, remove the battery.
  2. Activate and hold 5 seconds Mcubuka's power key.
  3. Connect the battery and run the device.

If the battery is built into the housing

  1. Disable computer.
  2. Connect MacBook via MAGSAFE or via USB-C with an external power source.
  3. On the built-in keyboard (left), activate simultaneously and hold down the "SHIFT-Control-Option" button + the power button for at least 10 seconds.
  4. Enable MacBook with a standard method.

Combinations of keys on MAS computers for different reset options

The system parameters of the marked computers to the default values \u200b\u200bshould be reset in the following sequence:

  1. Enable your computer through a standard power supply.
  2. After 3-5 minutes after switching on, pull the plug of the power board from the outlet.
  3. After 15-20 seconds, re-connect the BP cord for the supply network.

For XSERVE computers (CPU Intel): power off is activated by activating the power button and holding it for 5-7 seconds.

Information for thinking

User actions aimed at reset SMC do not change the contents of the PRAM series memory microcircuits (NVRAM) computer Systems Mac built under Intel microprocessors.


As for any other computers, MacBooks are also inherent on office keys.

Users computers MAC. It will not be superfluous to remember that SMC (system control controller) ensures the operation of the following low-level (and other) functions:

  • battery tank control
  • tracking temperature elements,
  • activation / deactivation of the position of the panel with the display,
  • tracking activation / deactivation of the power button,
  • controlling motion sensors,
  • enable / disable keyboard backlight,
  • control the operation of the external light sensor,
  • connecting an external display.

Reset the non-volatile RAM on Mac

The non-volatile memory microcircuit (NVRAM) is present in the diagrams of many laptop models. Memory chip is intended to save the so-called settings. quick access. For example, the area of \u200b\u200bthe NVRAM chip standard stores:

  • installed sound volume level,
  • information about the boot disk,
  • screen resolution parameters,
  • nuclear error data.

A complete list of settings stored in NVRAM depends on the system configuration, as well as from the number of devices connected as external modules To MacBook.


The appearance of such messages on the McBook screen may indicate the presence of firmware errors
