When the users use this mode to start their systems, the system performs a quick storage space test along with checking the hard disk for any other hardware bugs.

Why should you use Internet Recovery to reinstall Mac?

Well, this one of the most frequently asked questions amongst the ones operating Mac Systems. Why take all the trouble and opt for Internet Recovery instead of going the conventional way? In the following points, we list the reasons that make reinstallation of Mac through Internet Recovery an intelligent option.

  • One doesn’t need an Operating System disc to perform the reinstallation. This is helpful in cases when you are not carrying the OS disc and want to perform the Mac reinstallation immediately to carry on with your work.
  • There is no need for the user to download separate Operating System files. The Internet Recovery mode will download the installer files, and as a user, you are saved from the trouble of downloading them yourself.
  • The method is less complicated than the conventional method of downloading and installing the Mac OS X. This is helpful for users who aren’t very keen on the technical aspects of the installation process.

What should I do before opting for Internet Recovery?

Here are the points that must be kept in mind before going for the reinstallation of Mac through Internet Recovery mode:

  • For obvious reasons, you must have an internet connection. Users must use their DHCP on the WiFi or any Ethernet Network to install the Mac OS X.
  • For the ones who have purchased the OS X from any Apple Store, they might be prompted to enter an Apple ID or password that was used to purchase the OS X.
  • Users must note that the time taken for the reinstallation of OS X directly depends on the speed of the internet connection being used.

1) Access recovery mode by holding down the Apple Key and R Key.

2) Users must ensure that they are connected to the internet. We recommend that you use a private network for the same, and avoid any public network due to its configuration. Also, the installation file happens to be large which may take quite a lot of time on any public network.

3) Now, power off your Mac; Apple Shut Down. If you experience the OS not responding, simply press and hold the power button until the Mac switches itself off, and then wait for 30 seconds.

4) Power on your Mac. Hold the Apple Key and R key until you hear the chime noise. Once heard, it will start the OS X in Recovery Mode.
