Title: How to Clean Install El capitate with GTX 980 TI??
Post by: 72pixel on July 28, 2016, 02:17:11 AM
Hello, I'm a freshman.
This is a little stupid question.

I have purchased GTX980TI from you before.
And also Install the graphic card properly on Mac "El capitan".
There's no problem. Working great!
But Now, i have an issue with "Clean Installing OS X" by Bootable USB on Mac.

What i did try for.
1. Usually Hold 'Alt' key
2. Showing the Bootable USB on Screen and select the El capitane USB
3. But can't access install screen, just reboot and white error screen. it says like press enter to reboot...

I tried many times. But I couldn't reinstall El capitate with New 980TI.

How should i do for clean install OS X with this Graphic card?

please help me. :-[

// Solution

I just found the solution.
Here is the steps for clean install.
1. Start the computer and Press/Hold Command- S until you see Single user mode
2. To the commend prompt, Type: nvram boot-args="nv_disable=1" and hit enter.
3. Type: reboot and hit enter
4. Now you can do clean install...Hold alt ...select USB or Recovery Mode
5. After install a new OS to your new drive, you must re-install the Nvidia Web Driver
6. Reboot,
7. Open Terminal Windows and Type: sudo nvram boot-args="nvda_drv=1" and hit enter.
8. Reboot.

I followed the step. I did clean install, but I stuck at step 7.
I type ( sudo nvram boot-args="nvda_drv=1" ) and hit enter.
It says ( nvram: Error setting variable - 'boot-args': (iokit/common) general error )

How can I delete "nv_disable=1" without error??

// [SOLVED] the Problem.

Do not reboot after step 5. Just skip step 6.
