Mac OS X - HOW-TO fix horizontal tearing on Macs with nVidia Graphics
Nice thing about El Capitan is the ability to install the nvidia web drivers easily which is what I did on my 2010 mini which seems to help with this tearing issue. If 10.7 is doing the job for you then I would leave it alone.

Installing this driver requires a modification to the distribution file within the package to prevent it from checking the system for the correct definition and allowing it to completely install.

First, download the alternate driver for the Mac Pro Nvidia Driver for your OPSYS.

For Yosemite 10.10.1 use
For Mavericks 10.9.5 use:
For Mavericks 10.9.5 after the March update (13F1066) use:
The first post of this thread also lists alternate drivers for other versions of mountain Lion and Mavericks.

Place it on the desk top and open terminal and enter the following command in order to allow it to be installed on non mac pro machines running nvidia graphics.

pkgutil --expand ~/Desktop/<file name you just placed on your desktop> ~/Desktop/WebDriver
(example: pkgutil --expand ~/Desktop/WebDriver-334.01.03f01.pkg ~/Desktop/WebDriver)

Open up your newly created folder 'WebDriver' on your desktop and search for the distribution file, edit with TextWrangler/Text Edit and change var found_hardware = 0 to: var found_hardware = 1

Now that we have made the edit, need to repackage the installer. Remove the original .pkg from your desktop and type:

pkgutil --flatten ~/Desktop/WebDriver ~/Desktop/<orginal file name>
(example: pkgutil --flatten ~/Desktop/WebDriver ~/Desktop/WebDriver-334.01.03f01.pkg)

You have now edited the .pkg installer to prevent from checking if you have the correct system definition!

Hope this helps. It totally cured the tearing issues for us on all our 2010 mac minis whether running mavericks or yosemite.

Turning off "adjust video refresh rate to content frame rate" for me also greatly reduced tearing in older 480p content.

If even this fails to remove the tearing, enabling a momentary VNC connection (screen sharing) with the mini from an iPad or another mac computer will also remove the tearing.

Hi, I have a macbook pro with retina display. The operating system is El Captain 10.11.5 the graphics card is Intel Iris 6100. The Nvidia driver download doesn't work. I get a non compatible message. My problem is horizontal tearing. Any advice?
you don't have a nvidia gpu obviously. ensure vsync is turned on and post a debug log (wiki) maybe

What is the link for the El Capitan driver?

Mark, I believe this is what you are looking for.
Well, I followed the original instructions with WebDriver-346.02.03f01, OS X 10.10.5, Mac Mini Server 2010 but:

Quote:Open up your newly created folder 'WebDriver' on your desktop and search for the distribution file, edit with TextWrangler/Text Edit and change var found_hardware = 0 to: var found_hardware = 1
didn't exist, but the line:
var supportedOSBuildVer = "<number here>";
existed, with a different build number, so I edited it to match my build number
var supportedOSBuildVer = "14F2109";

and off we went...
installed fine, then at the end a message appeared saying it wouldn't enable the nVidia drivers as there was a mismatch, but there were some available, 'Would I like to download the newer ones?"
Ho yes!!

All installed and working with jerk-free HD content
Haywooj - thanks. Still working even with WebDriver-367.15.10.35f01
