Hi there, I'm a noob but have spent the last 2 days devouring the forum and learning alot. If I phrase things wrongly or show signs of misunderstanding please correct me.

I have been running 10.8.5 for ages so recently decided to use a spare SSD to try El Capitan 10.11.3.

At first I think I used Chimera to create a USB with Unibeast and I eventually got it installed and working, although only one screen was working and it wasn't displaying fulll screen, the aspect ratio was also off. I downloaded the latest Nvidia 10.11.3 compliant web drivers and more or less immediately both my screens were displaying wonderfully at full resolution. Then I went to bed, woke up the next day, and could not get my El Capitan SSD to boot fully.

During this whole process I was learning alot about Clover. So I decided to start again and make a Clover USB. I got to completing installation (using the USB bootloader and then mounting the SSD) after a few hickups, and everything seemed fine, except the screen. Again only one monitor working and at the wrong resolution. So then I installed the latest 10.11.3 compliant Nvidia web drivers and restarted the machine. But this time the Nvidia drivers didn't seem to be working - the second monitor remained without a signal and the first monitor remained at the wrong resolution.

I have the Nvidia preference pane and menu, and Nvidia web drivers are selected (though this is redundant apparently as I'm using the nvda_drv=1 bootflag), but there is no difference between before and after installation of the drivers.

I have tried uninstalling and reinstalling the drivers with frequent reboots... no difference. I've had some slightly irratic startup behaviour as well, getting the No Entry sign and Kernel panics etc... but it's pretty stable now.

I noticed in the Nvidia preference pane, under the ECC tab, that each slot displays "no device found", not sure if that's important. However, the graphics card does show in the "About this mac" window under "OVERVIEW" and also under "DISPLAYS". But under "displays" it just shows one monitor which it lists as 17.8" 1024x768 (my monitors are actually 22").

In my SDD EFI "drivers64uefi" directory i have:
- FSInject-6.efi
- HFSPlus.efi
- OsxAptioFix2Drv-64.efi (tried replacing this with OsxAptioFixDrv-64.efi to no avail)
- OsxFatBinaryDrv-64.efi

In my kexts for both 10.11 and 10.10 i have:
- AppleIntelIE1000e.kext
- AtherosE2200Ethernet.kext
- FakeSMC.kext
- RealtekRTL8111.kext

I haven't changed anything else in the EFI.

Using Clover Configurator I've also tried different SMBIOS. MacPro5.1, MacPro3.1, iMac14.2 and currently iMac14.1. I've tried a ton of different bootflag settings. But nothing works.

I'm thinking about creating a new USB with Chimera as at least that seemed to work the first time. But I've heard so much good stuff about Clover I feel this is the wrong way to go. Surely clover can fix this.

Advice greatly appreciated.

Hi All...

First post.

I would consider myself a noob, even though this is my second build. The first was for my son with new kit, Asus Z97 Pro 3, i7 4790K and a Nvidia GTX 750Ti. This build went so smoothly it inspired me to try with some old kit that was used for a *cough* Windows box.

I appear to have the same issues as Cyberdogg and was hoping somebody might be able to help.

This current build is:

El Capitan 10.11.3
GA-X58A-UD3R FF Bios
3.2 Ghz i7 970
6GB Ram
Nvidia GTX 750 Ti

I've managed to get everything working, Audio, Network, Restart and Shutdown. Unfortunately no matter what I do, I cannot get the graphics to work properly.

This system was built with the latest Unibeast 6.1.1 and Clover. The Mac recognises the graphics card and is shown correctly in About This Mac, but shows the Display as 17.8" 1024 x 768, even though its connected to a new 4K2K Acer monitor.

The latest Nvidia Web Drivers have been installed, 346.03.05f02 and like Cyberdogg under the Nvidia Driver Manager - ECC each slot displays No Device Found.

I originally had the monitor connected via DVI and its now connected using HDMI, which didn't make any difference.

My current Boot flags are set to dart=0 nvda_drv=1 npci=0x2000 arch=x86_64, and I've tried with just dart=0 nvda_drv=1.

The SMBIOS is set to MacPro 4.1 and I've tried 3.1, 5.1 and iMac 14.1, without any success.

I've read through all the posts and have spent the last week trying all the different settings to get the graphics to work.

Any advice would be greatly appreciated.

I didn't start a new thread as we are experiencing the same issues with the display resolution set to 1024 x 768 and the ECC in the Nvidia Driver Manager showing No Device Found for each slot. OK, I don't have a second screen, but it's probably related.

I should add that after selecting the Nvidia Web Driver and rebooting, it reverts back to the Native driver.

Will it really help to start another thread, if it does, I will?

Apple 4K friendly macs (and hence definitions):

https://support.apple.com/en-gb/HT202856

Try the 2013 Mac Pro - 6,1.

You may need this fix (number 4):

Alternatively you can use the app attached at the end of this post (worked for me):

Thanks Yoga, I'll give this a try and let you know how I get on.

My monitor supports Display Port, HDMI and DVI, my GTX 750Ti has DVI and mini HDMI. I'm currently using the HDMI and have tried the DVI.

Hi MoosinUK, our systems are very different. But it might be a matter of chosing a MacMini or iMac 13,2 in the config.plist. I think you want to find the nearest equivalent to your actual hardware. You can find a list of the chips used by real macs on geekbench's site.

I ended up doing a fresh install. New USB and everything.
