Hey folks,

Just wanted to point out something that was a little hard to debug.

Today just after updating Clover to r4061, my install boot got stuck. No kernel panic no nothing, just it wouldn't transit to the graphics mode from verbose. So I figured it must be something going on with the graphics.

I am using the native Intel HD 4600 from my Gigabyte motherboard. Before I didn't need to inject it explicitly in Clover. But now, it seems this has become mandatory. The inject intel was automatically selected by Clover already, but what it needed to make it boot properly was the ig-platform-id property.

To boot the first time, under Clover/Graphics Injectors/*-platform-id, enter 0D220003

Then after booting in config.plist add:
Code:
    <key>Graphics</key>
    <dict>
        <key>Inject</key>
        <dict>
            <key>Intel</key>
            <true/>
        </dict>
        <key>ig-platform-id</key>
        <string>0x0D220003</string>
    </dict>

This config is only for HD 4600, it will be another value for other intel cards.
 
The default ig-platform-id was 0D220003, I wonder if it has changed...
