Hello

I have installed Mac OS High Sierra on my 250Gb SSD

The setup went pretty well
Then I installed the NVIDIA Web Drivers and
rebooted my computer

However now I have absolutely no signal coming out of my computer, I can't even see the ASRock startup screen :cry:

My screen works just fine with my laptop
I've tried using the motherboard VGA port : same problem

I don't know what to do, maybe rebooting my computer a bunch of times has damaged my power supply ? (I've rebooted it like 30 times today because the installation failed the first time)

Maybe something went wrong with the drivers ?

What do you guys think ? :confused:


UPDATE : My motherboard had just randomly died. It was several years old so I guess that's fine. I replaced it and everything worked fine afterwards.

VGA is not supported - Apple do not use it - Use a digital connection.
HDMI does not work either

The GTX 760 has native support - No additional drivers required.
I couldn't set the right resolution and the animations were really slow so I thought I needed the latest drivers

Yes, agreed, if there's no video signal for the BIOS try a CMOS reset and boot through the motherboard HDMI - if possible. If not, take out the GTX and try again. If still no signal and the motherboard is somehow faulty or damaged you should get a POST beep signal to tell you of any problem. Check you have a mini speaker attached to the motherboard pins etc.

If you *do* get back into BIOS (sigh with relief!) and again boot using iGPU, then remove the Nvidia driver kexts, clean the cache and reboot into the BIOS and change to PCI-e First Init graphics, put your GTX in, boot again. See if you get an unaccelerated (or, as should be, a working) desktop and report back.:thumbup:

I know this is an old thread, but it shows up high in search results, so I wanted to add a comment:

As mentioned above, you have to boot on a DVI connection, but you can *always* plug in HDMI or DisplayPort monitors AFTER you have booted up and logged in -- they are both fully hot-pluggable. I have to boot with DVI, but then I plug in my 2 DisplayPort monitors after booting (the DP cables, not the power cables), and it's all good. Because the ports clearly work, that means this boot issue *should* be fixable with a software patch, but it's well beyond my skill level.

EDIT: Ugh, posted to the wrong thread, but still helpful. Going to cross-post to the correct thread...
