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: "Thinkpad x260 - battery charge threshold"
I'm dual booting MacOS Catalina and Windows 10 and now Vantage does not give me the option to set battery threshold anymore, it is permanently stuck at 50% with no way to change the setting. Is there a way I can control the battery charge threshold, as Vantage does, using registry keys?
Information has been written to the UEFI which means that Vantage identifies my x260 as a MacBook Pro, so doesn't show any of the battery settings.
Any advice welcomed, thanks.
