boot-flag problem (nvda_drv=1) after update to 10.10.5

[Danielani]

On October 10, 2015. I tried to update my installed copy of Yosemite 10.10.1 to 10.10.5.

 

After the installation the computer started booting but at some point the screen switches to no signal (dark) and the graphics fan spins out of control (high fan noise).

 

To fix it I use this boot flag “nv_disable=1” to boot into the OS, and then installed Nvidia graphics driver (WebDriver-346.02.03f01.pkg), and after the installation I tried to boot with this boot flag (nvda_drv=1) but with no change (unsuccessful).

 

I rebooted into the OS with disable graphics command (nv_disable=1), and then used “Chameleon Wizard” to create SMBios.plist with iMac13,2 profile and then replaced the SMBios.plist that was there which had Mac Pro 6.1 profile in the “Extra” folder, and I then rebooted the computer. The computer booted into the OS successfully, but less than a minute later I notice that the graphics card fan was spinning out of control or extremely too fast (very noisy).

 

I rebooted with this boot flag “nvda_drv=0”, and that solved the fan problem, so I edited my org.chameleon.Boot.plist and removed “nvda_drv=1” boot flag, and rebooted into the OS successfully, but less than a minute later I notice that the graphics card fan was spinning out of control again.

 

I restarted the computer but as I press the first key to enter the boot flag before booting into the OS, I noticed that this bootflag “nvda_drv=1” was already there, so I used the “backspace” key and got rid of the “nvda_drv=1” boot-flag, and then pressed enter, and the computer booted into the OS successfully with no more fan noises.

 

My question is, how do i get rid of the embedded boot-flag “nvda_drv=1”, so that I can have the computer boot straight into the OS again, without having to pause and repeat the process above.

Thanks
