In the Boot Args section of Clover, enter the boot flags. |
Clover Boot Flags:
![]() |
| An example of verbose mode. When the computer hangs (stops), the last message you see is the message you should search to find a solution. |
Verbose Mode:
-v
Safe Mode:
-x
Single User Mode:
-s
Zone Postponing: (use if hanging)
-no-zp
Single CPU core mode:
cpus=1
No Kext Cache Mode: (When changing kexts)
-f
Disables VT-x or VT-d:
dart=0
Verbose Mode:
-v
Enable NVIDIA Web Drivers: (do not use with nv_disable=1)
nvda_drv=1
Disable NVIDIA graphics cards: (do not use with nvda_drv=1)
nv_disable=1
Kext Dev Mode:
kext-dev-mode=1
If you're stuck at [PCI Configuration Began]:
npci=0x2000
npci=0x3000
Set Maximum Memory (RAM): (In megabytes)
maxmem=4096
maxmem=8192
Troubleshooting:
If you are having any trouble, first try this string. It works on a lot of systems with Intel HD Graphics to get into the OS X Installer from a Unibeast USB.-v -x -s -no-zp
If you have an NVIDIA Desktop GPU, use this string to boot into the installer:
-v -x -s nv_disable=1
If all else fails, or you don't know where to start, use this string:
-v -x -s -f cpus=1 maxmem=4096 nv_disable=1 -no-zp
If you have an NVIDIA Desktop GPU and you've installed NVIDIA Web Drivers (Link), use this string:
-v nvda_drv=1 + your bootflags (do not use nv_disable=1)
Common Issues:
If in verbose mode, a message about [IOBluetoothHCIController][start] -- completed or something similar appears, it normally has to do with a graphics issue. If you have an NVIDIA or AMD GPU, use nv_disable=1 and it should boot. Otherwise, boot into safe mode.
Comment any issues you have and I could recommend you a set of bootflags to use!
