Boot failures are most commonly caused by firmware settings, incorrect OpenCore configuration, or USB mapping problems. Here is a structured approach.
Step 1 — Boot with Verbose Mode
Add -v keepsyms=1 debug=0x100 to your boot arguments.
Step 2 — Check Firmware Settings
Disable Secure Boot, Fast Boot, and CFG Lock. Set SATA to AHCI. Enable UEFI boot mode.
Step 3 — Validate OpenCore Configuration
Run ocvalidate on your config.plist. Use ProperTree to perform a clean snapshot.
Step 4 — Test with a Fresh USB Installer
Recreate the installer on a different USB drive and try a USB 2.0 port.
Expected Results
- Verbose boot passes the previous stopping point
- The installer sees the target disk
- Keyboard and mouse respond during the installer

Original Question: "macOS recovery can’t contact recovery servers."
I have made a high sierra drive with open core and booted to it. When I go to OS X base system and click reinstall macOS it says it can’t contact the recovery server. I’ve used ping to make sure the internet is working and made sure the date is set.
