Unable to enter internet recovery mode

Hi, My mac suddenly went into a black screen, I have tried to restore it by time machine which led to erased HDD and black screen! Then I decided to use internet recovery mode. I reset PRAM/NVRAM and SMC, then entered internet recovery mode. After filling the bar under the global logo it went to gray screen with a spinning circle and after 10 seconds restarted into a black screen with no function again! I have tried it several times and the result was the same. Help me with reinstalling a fresh mac OSX.

MacBook Pro 15″, macOS 10.15

This will work if the Recovery Volume is still functional:


Install El Capitan or Later from Scratch


If possible, back up your files.


  1. Restart the computer. Immediately, at or before the chime, hold down the Command and R keys until the Apple logo and progress bar appear. Wait until the Utility Menu appears.
  2. Select Disk Utility from the Utility Menu and click on the Continue button.
  3. When Disk Utility loads select the target drive (out-dented entry w/type and size info) from the Device list.
  4. Click on the Erase button in Disk Utility's toolbar. A panel will drop down.
  5. Set the partition scheme to GUID.
  6. Set the Format type to APFS (SSDs only) or Mac OS Extended (Journaled.)
  7. Click on the Apply button, then wait for the Done button to activate and click on it.
  8. Quit Disk Utility and return to the Utility Menu.
  9. Select Install OS X and click on the Continue button.


If Internet Recovery is the only way:


Internet/Network Recovery of El Capitan or Later on a Clean Disk


You will need a fast, working Internet connection, preferably, Ethernet. If you must use Wi-Fi, you will be asked to select your network and enter the network password.


  1. Restart the computer. Immediately, at or before the chime, hold down the (Command-Option-R) keys until a globe appears.
  2. The Utility Menu will appear in from 5-20 minutes. Be patient.
  3. Select Disk Utility and click on the Continue button.
  4. When Disk Utility loads select the target drive (out-dented entry w/type and size) from the side list.
  5. Click on the Erase button in Disk Utility's toolbar. A panel will drop down.
  6. Set the partition scheme to GUID.
  7. Set the Format type to APFS (SSDs, only if installing Mojave or Catalina ) or Mac OS Extended, (Journaled.)
  8. Provide a volume name, usually "Macintosh HD."
