How To Use Recovery Mode When Reinstalling A macOS

A macOS reinstallation might be needed for different reasons. Maybe your Mac is not working, and the only way to get the problem fixed is through reinstalling the operating system. If you are planning to sell your Mac, it’s a good practice to restore it to factory settings and reinstall the macOS. Regardless of your reason, there’s an easy way to reinstall macOS.

macOS Recovery Made Easy

One of the best and proven methods to reinstall macOS is using Mac Recovery Mode. Since macOS is technically installed on your Mac through the Mac App Store, it only means no physical installation disks are required. Hence, it is possible to install macOS via the Internet using Recovery HD.

What You Need to Re-install macOS via Recovery Mode

There are two primary things you need to reinstall macOS using Recovery Mode: a backup and an Internet connection. If you are planning to erase your Mac’s data because you are selling it or you just think that a clean slate may possibly fix the issues, you will need a backup of your important documents. How you backup your Mac will depend on what you want to happen. You can back it up in such a way that you can still recover your current Mac’s operating system version. You can also do a clean install. Either way, these top methods to back up your Mac will help.

You will also need a reliable Internet connection throughout the process. If possible, use a network with WPA or WEP security. But if you are connected to a home Wi-Fi network, this won’t be a problem. An Ethernet connection can also ensure a secure and uninterrupted Internet connection.

How to Use Recovery Mode to Re-install macOS

To reinstall macOS via Recovery Mode, simply follow the steps below:

  • Boot your Mac while holding down the Command + R keys. Do this until you hear the startup sound and see the Apple logo.
  • A macOS Utilities window will appear. Here, you will see some options, including Reinstall macOS, Restore From Time Machine Backup, Disk Utility, and Get Help Online.
  • If you wish to erase your Mac’s data before reinstalling macOS, go to Disk Utility and click Continue. Otherwise, proceed to step 8.
  • Select the disk volume you like to clear. Click Erase or go to View > Show All Drives. Take note that this step will delete all your data, so be sure you have already backed up your important files.
  • Set the Format to Mac OS Extended (Journaled). If available, select the GUID Partition Table as the Scheme.
  • Click the Erase button and wait for a few seconds.
  • Select Disk Utility > Quit Disk Utility. The macOS Utilities window will pop up again.

If ever you want to sell your Mac, shut down your computer once the setup wizard appears. That way, the new owner can enter his own details. However, if you will still be using it, continue setting it up.

How to Install a Newer Version of macOS via Recovery Mode

Aside from the Command + R key combination, there are other ways to reinstall macOS via Recovery Mode. Other options allow you to decide whether you wish to install the newest macOS version that is compatible with your Mac or install the macOS version that came with your computer.

  • Command + R – If you are giving away or selling your Mac, this option is for you. This will install the most recent version currently installed on your Mac.
  • Option + Command + R – This option allows you to upgrade to the most recent macOS version that is compatible with your Mac.
  • Shift + Option + Command + R – If your Mac is running on Sierra 10.12.4 or higher, this will let you install the macOS version that came with your Mac or the closest version to it that is available.
