Introduzione

Internet Recovery has a number of useful applications. This guide will show you how to use Internet Recovery to install a fresh copy of macOS to a blank or corrupted SSD.

Internet Recovery is only available on Apple computers made after 2009. If your computer was released in 2010 or 2011, you may need to update to the latest version of macOS to enable Internet Recovery.

  1. Shut down the computer.
    • Shut down the computer.

    • If you're installing MacOS to a new drive with Internet Recovery, you can skip this step.

    I thought this guide is for a completely new SSD, but in this example MacOS appears to already be running. Is the target SSD connected internally via SATA or is this guide for a USB based second SSD that will also run the OS?

    In the latter case, is the intent to run internet recovery on the new SSD and then open the machine up and connect it directly, replacing the old disk?

    Sorry for the confusion, Orun! The new SSD guide shares a few steps with the general “boot to internet recovery mode” guide. If you’re installing MacOS to a new drive, you can skip this step. :)

    Does this option still work if using a Bluetooth keyboard?

    Chad Neumann - Replica

    Chad, this option should still work if using a bluetooth keyboard. If you’ve paired the keyboard to the computer already, then it should connect quickly enough to register the keypresses. That said, it’s definitely less reliable than using a wired keyboard! And every bluetooth keyboard is different—one might work, and another might not. Good luck!

    After I entered password and loaded up internet recovery a Question Mark appears and flashing. What do I do next?

    Never mind. When I tried a second time it went to the Disk Utility. I was able to complete the process.

  7. Before you can install macOS to the new drive, you'll need to format the drive so the installer can recognize it. Open Disk Utility from the recovery menu, select your drive, and click the Erase button toward the top of the Disk Utility window. Make up a name for your drive, and make sure the format is set to Mac OS Extended (Journaled) or APFS.

    • If you don't see your drive listed in the Disk Utility menu, select Show All Devices from the View section of the menu bar.

    • Once the new drive is formatted, press Command + Q to exit Disk Utility and return to the recovery menu.

    Bought the OWC recommended drive from fixit (for 2012 Macbook air) and it was pre-formatted—so was able to move right on to restoring from time machine backup — worked great!

    When can I use Time Machine to restore my data. Can I use it in this step or I have to install MacOS first, then use time machine?

    ahmad albulihy - Replica

    Ahmad, I was under the impression that you needed to install MacOS before you can restore a time machine backup. That said, now that you ask I am not sure! It could be possible to restore your data and the OS with Time Machine. If you already have a TM backup at this step, give that a try and let me know how it goes.

    I’m upgrading to a SSD on my 2011 iMac, running MacOS High Sierra. Updating to Catalina is prevented by the age of the computer.

    Should I choose APFS as the format for the new SSD, rather than Mac OS Extended (Journaled)?

    It appears to be compatible with High Sierra, and some quick research indicates that APFS is meant to be optimised for flash based storage like an SSD.

    Andy Waller - Replica

    I think I’ve answered my own question. After futher reading of this article. I’m going to stick with MacOS Extended (Journalled) to ensure that I maintain compatibility with my existing Time Machine backups to the new drive. Its also mentioned that during installation of High Sierra, it will decide which disk format is more appropriate automatically.

    It would certainly be interesting to see how much faster APFS is for SSDs.

  8. Back at the recovery menu, select Install macOS .
    • Back at the recovery menu, select Install macOS .

    Can I choose which OS version to install at this point? I will want to install Mojave, but since there’s a newer OS (Catalina) out now will that version be installed without giving me a chance to choose?

    Lee Wolf - Replica

    Lee, unfortunately I do not think this interface will let you install older versions of macOS—it just automatically grabs the newest version. If you want to install Mojave, you’ll have to make a USB installer!

    • Follow the prompts to install macOS, selecting the newly formatted disk as the target for the installation.

Conclusione

Your computer may restart several times during the installation of macOS. Once the installation is complete, you can use Migration Assistant to transfer data from your old drive to the new one.
