OS X Yosemite installer shows blank/black screen when using Clover

Posted on by Jan

This is a heads up for everybody with an Nvidia GTX 760 (other Nvidia cards may be affected as well) trying to install OS X Yosemite 10.10 using Clover on a Hackintosh. If you’re getting a blank/black screen at the start of the installation, try to add the boot flag nv_disable=1. My screen was getting dark just after the installer displayed DSMOS has arrived when using the -v verbose boot flag. It always happened right after the installer was switching from text mode to graphics mode.

        <key>Boot</key>
        <dict>
                <key>Arguments</key>
                <string>dart=0 -v kext-dev-mode=1 nv_disable=1</string>
        ...(more)

Once OS X Yosemite has been installed, the nv_disable boot flag is no longer required and should be removed.

Best graphics card for an OS X 10.7 Lion Hackintosh

Posted on by Jan

If you’re about to build a new OS X 10.7 Hackintosh or to replace the graphics card in your current Hackintosh rig, you may want to consider the AMD Radeon HD 6870. Power-wise it’s a mid-range graphics card which comes with an affordable price tag. The big advantage of the Radeon 6870 is that it fully supports Quartz Extreme and Core Image (QE/CI) in OS X Lion out of the box, no additional kernel extension like ATY_y.kext needed. All you have to do is to set graphics enabler to YES in Chameleon’s com.apple.Boot.plist. If you don’t need a high-performance gamer graphics card, this is the one to go for!
