Multi Monitor Kernel Panic

[kb3wmh]

I just got a second monitor for my Hackintosh, but whenever I plug it in, I get a kernel panic. If I plug it in when the computer is shutdown, I get a kernel panic in the middle of the boot process. I can get it to boot with my original monitor, but if I plug in the second one afterwards, I get an immediate panic.

Also, I often get kernel panics unless I boot in verbose mode.

I am running Mac OS 10.10.4. I have a Gigabyte GA-z87-D3H motherboard, with an Intel i5 4670k. I don't have a graphics card; instead I am using the onboard HD 4600 graphics. The main monitor is plugged in via HDMI, and the secondary monitor is plugged into the VGA port.

I am completely stumped by this and would appreciate any help.

Thanks.

OSX doesnt support VGA.. Do you have a DVI port on your motherboard?

Wow. Yeah, that makes sense, as Macs have not been sold with VGA for a very long time. I have a DVI port, so I guess I'll just have to buy a cable and stick with Windows until I get one. Oh well.

Thanks again!

So, I got a DVI cable. However, when I boot the computer, instead of the normal Chameleon GUI, I get a text prompt. If I select Macintosh HD, the computer restarts. I can use the text prompt to boot into Windows, I only have the problem with Mac OS.

Will I need to reinstall?

It boots if I unplug the cable and then plug it back in after the computer has booted.

Your motherboard has DVI,HDMI,DisplayPort so either use DVI or HDMI or DisplayPort don't use VGA OS X doesn't support VGA. its common to cause kernel panics when using VGA.

The DVI works, but I have to wait until after the computer boots to plug it in.

Fixed it-- just had to set chameleon to 1280x1024.
