internal hd won't mount

Brand new MacBook Pro 2019. Never mounted the internal HD. Placed folders on desktop and they disappeared? iCloud does't download my info? I've tried recovery `& install new system. Nothing works & I'm out of country. How do I fix this with just online help?

MacBook Pro 13”, macOS 10.14

Assuming there is nothing physically wrong I would try reformatting the SSD then reinstalling macOS. Here is the procedure using the Network Recovery option.


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


     If possible back up your files before proceeding.


  1. Restart the computer. Immediately, at or before the chime, hold down the (Command-Option-Shift-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 (will be the out-dented entry) from the side list.
  5. Click on the Erase tab in Disk Utility's main window. A panel will drop down.
  6. Set the partition scheme to GUID.
  7. Set the Format type to APFS (SSDs only) or Mac OS Extended (Journaled.)
  8. Click on the Apply button, then click on the Done button when it activates.
  9. Quit Disk Utility and return to the Utility Menu.
  10. Select Install OS X and click on the Continue button.


It would be better to connect to the Internet using Ethernet instead of Wi-Fi because of speed and reliability.
