    HD4400 Boot Graphics Glitch

    Can you post your EFI and tell me what options you have changed in BIOS? Thanks. Yep, same issue. However, it did change a bit... When booting, I no longer have to put the display to sleep to fix the weird graphics issue. But, I'm still getting the same issue in Firefox/Chrome as seen in the...

    Backlight does work better w/ your patch. More linear versus quadratic. Removed IntelGraphicsDVMTFixup as that was causing problems with backlight control. I finally had time to read the script(s) and it gets my approval.

    I see exactly what you're saying and do not know what caused that to change. I have not touched that, nor have I seen a patch that's done anything like that. Reverting back to default DSDT. Good catch.

    Checking into DSDT now. May be a kext causing that.

    1. BIOS does NOT have CSM, but will let you change to Legacy. I do not want to use legacy to boot; I want to use UEFI. 2. Backlight control works. No need to patch for backlight control. As stated in post 16.

    DSDT ✔ IOReg ✔ Command Output ✔ Clover Folder ✔ Preboot Log ✔ Kext Cache Output ✔ Since you haven't told me what I'm missing, the only thing that I can assume is that the DSDTs from Clover are apparently not good enough. Attached are the DSDTs from patchmatic. CSM cannot be enabled as...

    Expect people to not realize that it can be in two places. State that in your guide. Not everyone has the time to read everything thoroughly. Re-read the first post. It clearly states that there's a graphics issue. Looks memory related. Define "PR files".

    Better? Somehow copying FakeSMC.kext only copied the Contents folder... Took me a minute to figure it out. Also, I had more time to review your guide, and it contradicts what you say when talking about "essential kexts". The "Preparing Essential Kexts" area specifically says to install them into...

    More better? Just for testing. I'll change things once we figure it out. These kexts will be removed from Clover. Mark-Laptop:~ mark$ sudo kextcache -i / Kext with invalid signatured (-67062) allowed: <OSKext 0x7ffad44c2c20 [0x7fff95cb6af0]> { URL = "FakeSMC.kext/ --...

    Kext cache output was minimal. See below. Mark-Laptop:~ mark$ sudo kextcache -i / KernelCache ID: 107A09B4ED8DB26683F929602EC76FEA

    Attached Also, keep in mind that I have both the patched DSDT (as you'll see), as well as the system's. Thanks for your help! Edit: Forgot to mention that there's no CSM option in these BIOS. I can either change from UEFI to Legacy, or vice versa. I really don't want to boot using legacy BIOS.

    Hallo, when I boot my Toshiba P55-A5312 w/ macOS High Sierra, I get this lovely screen You can clearly see that the mouse icon works just fine, yet the image behind it is corrupted. I've tried many patches, kexts, IG-PLATFORM-IDs, etc, with no avail. The only fix for this is to put the...
