Issues related to boot up, display, battery performance, and system slowness, are the common computing problems that might start bothering your MacBook, and eventually turn it into a sluggish device.

Method1: Reset PRAM

It might sound technical, but it is nothing but a small amount of memory on your computer. Your Mac uses this memory to store the system settings. If you are facing booting issues or if your device has odd display glitches, then resetting PRAM can solve the problems. The process takes a couple of minutes, and it comprises the following steps:

  • Power down your MacBook either by pressing and holding the ‘Power’ button for a few seconds or by turning it off from the Apple menu.
  • Now, press and hold ‘Command+Option+P+R’ keys.
  • Now, continue holding the four keys until you hear the startup sound for twice.

That is all you need to reset your PRAM.

Method 2: Resetting the Battery (SMC)

Battery reset is an effective method to resolve a MacBook’s common battery related issues. The power settings and the fan on your MacBook get maintained by the Systems Management Controller (SMC). Any problem with the SMC can trigger several other problems such as:

  • Loud sound or high speed of the fans
  • Malfunctioning indicator lights, backlights, etc.
  • The device gets unresponsive to the ‘Power’ button.
  • The device shuts down unexpectedly.
  • The battery fails to get charged properly.

If your device is suffering from any of the issues mentioned above, then resetting the battery will help in resolving them. Battery reset method varies depending on whether your device has a removable battery or a non-removable battery.

Removable Battery

If your MacBook has removable batteries, then perform the following steps:

  • To reset your removable battery perform the following steps:
  • Shut down the computer
  • Disconnect all the plugged in power cords
  • Take off the battery from the back of the MacBook.
  • Continue pressing and holding the ‘Power’ button for 5 seconds.
  • Now, release the ‘Power’ button to release any stored charge.
  • Reinsert the battery.
  • Connect the power cable.
  • Press the ‘Power’ button to turn on the computer. It should resolve the battery-related problems on your device.

Nonremovable Battery

If your MacBook has non-removable batteries, then perform the following steps:

  • Shut down the computer
  • Disconnect all the plugged in power cords
  • Press the left side ‘Shift’+’Control’+’Option’ keys and the Power button simultaneously
  • Release the Power button and all of the keys at the same time.
  • Now, turn on the device by pressing the ‘Power’ button.
  • It should solve the problems.

Method 3: Restore Mac to Factory Settings

The two methods mentioned above should fix the common MacBook issues. But if the problem still prevails, then your last resort is to perform a factory restore. Restoring Mac to factory settings will certainly fix many problems such as program freezing, constant crashing, errors, persistent sluggish performance, etc. But along with that it will completely wipe out all the data stored on your computer. Thus, you should perform the factory reset only after creating the proper data backup. When you restore Mac to factory settings, you command your device to delete all the data on your computer and reinstall the operating system afresh. It means everything saved on your hard drive will get wiped out. That’s why you should create a proper data backup.

The Factory Reset Method

  • Reboot the computer
  • Hold down ‘Command+R’ keys. That will load the ‘Recovery’ function.
  • Select the Recovery HD. (Recovery HD is a hard drive portion reserved for the recovery function)
  • Next, select the ‘Disk Utility.’
  • Now, click the ‘Continue’ button
  • That will load the ‘Disk Utility’ window and here you will see a list of your hard disks.
  • Now, select the ‘Macintosh HD’ disk
  • Then, click the ‘Erase’ tab.
  • From the “format” drop-down menu, select ‘Mac OS Extended (Journaled).’
  • Then, click the ‘Erase’ button
  • That will initiate the erase process, which might take a few minutes.
  • Now, close Disk Utility and return to the ‘Recovery’ menu.
  • Next, click the wireless icon and select your wireless network. (Make sure that you have a good internet connection to download and install OS X.)
  • Next, select “Reinstall OS X.”
  • Then, click the ‘Install’ button.
  • That will begin the installation process for OS X.
  • Now, read and agree to the ‘Terms and Conditions.’
  • Then, specify the hard drive to which you want to install OS X. By default, the OS X gets installed on the drive that you had just erased.
  • The installation process might take 30-60 minutes to get finished. If you want to purchase the latest OS X, then enter your Apple ID and purchase it from Apple App Store.

With these steps, you complete restoring Mac to factory settings.


After the factory restore, you need to restore your data from the backup you had created. Along with that, you also need to reinstall all the programs and software that you were using earlier. It might appear as a highly bothering task to many users, but many others might consider it as an opportunity to start all over new. Moreover, taking this effort is worthy as it will bring back your Mac to its pinnacle of computing excellence by fixing so many issues.
