Hello, so today I opened up my laptop and it was in Safe Boot. When I put in my password it wouldn’t unlock it after a couple of restarts it allowed me to get in. But my Laptop was showing black boxes everywhere. I called Apple they had me Un Mount and Mount Macintosh HD , and erase and reinstall the OS. When I did that I kept getting an error message “Could Not create a preboot volume for APFS install”. After trying several times I called again. And the next person had me to go into internet recovery mode and try and install OS X Yosemite and no disk is showing up to select to reinstall the OS.
If anyone has ever had this problem and knows a solution please help!!
Thank you
