    Black Screen with MacPro 6,1 or iMac 15 or iMac 17 System Definition

    Was working on this issue for a few days while updating my desktop (High Sierra, GTX 950). Booting with two monitors connected (one DP, one DVI) caused a black screen and hang. Booting with the DVI cable disconnected works fine, and after booting I could re-connect the DVI to get the second...

    macOS 10.13.4 Security Update

    Some progress. I was able to get past the kernel panic and finish the install by using a FakeID of 0x12345678 for my Intel 5500u graphics (Lenovo Thinkpad X1 Carbon 3rd gen). However the update seems to introduce a problem with my graphics. It no longer boots with the correct ID of 0x16260006...

    [Solved] Thinkpad X1 Carbon High Sierra installer hangs

    Okay, I tried using the config_HD5300_5500_6000.plist from there.

    [Solved] Thinkpad X1 Carbon High Sierra installer hangs

    Hello, I'm attempting to install High Sierra on a 3rd gen Thinkpad X1 Carbon (i5-5300U). I'm using the latest RehabMan Clover (2.4k r4444) and mostly working off of this guide, at least for the BIOS and Clover bootloader settings, but of course using the High Sierra installer. I'm able to get...
