lubeats Posted November 23, 2017 Share Posted November 23, 2017 Hello everyone, I want to know if someone could help me solve my problem. I have installed MacOS Sierra and Mac OS High Sierra,both of them in different hard disks. Almost everything works fine, except my Intel HD Graphics 5500 card, I only have 7 MB in macOS as shown. I found a solution on the Internet where I should change the DVMT value from 32 MB to 64 MB in my BIOS. I unlocked my BIOS to do it but I have the same problem. In this forum, the user Fatboy was able to do it in his laptop DELL E7450 with the help of users Klaus, Jake and Herve and now I want to know if anyone could help me. My last update of attempts to solve my problem: I have VRAM in my video graphics but with some problems. I discovered that I had to activate Load VBios in the graphic item. I have set ig-platform-id to 0x16260006 and kext patch Name: AppleIntelBDWGraphicsFramebuffer Find: 06002616 01030303 00002002 00005001 Replace: 06002616 01030303 00003001 00009000 Name: IOGraphicsFamily Find: 0100007525 Replace: 010000eb25 When I turn on my laptop sometimes i get a kernel panic like a crossed out circle and then try and try again until the system activates, but I can not see almost anything because I have a blinking graphic. Then, I switch to sleep mode and I activate it afterwards and in that moment I can see almost everything well, except screen brightness. Could someone help me? I want to know how to get screen brightness output port like vga and hdmi battery status control keys brightness and some issues more ... PD. When I do not use my system for 5 minutes aprox my system restart automatically, That problem started when I activated Load VBios in graphic item. I attached photos and screenshots and my debug report. Thanks in advanced. debug_15575.zip Link to comment Share on other sites More sharing options...

Administrators Hervé Posted November 23, 2017 Administrators Share Posted November 23, 2017 The IOGraphicsFamily patch for High Sierra differs from El Capitan and Sierra. It is: Find: 0100007522 Replace by: 010000EB22 If you use the wrong patch, you risk a KP... Why do you enable "Load VBIOS" in Clover config? What VRAM problems does this solve?

lubeats Posted November 24, 2017 Author Share Posted November 24, 2017 Hi Jake Lo, I eliminated all your suggestions and I used your config.plist modified. When the system start, this delay around 10 min to arrive to the desktop, before that I have the same blinking graphic, and I switch to sleep mode and I activate it and in that moment I can see the desktop. Tell me Bro, How to patch my DSDT correctly, I got it extracting from windows with RW-Everything directly and copied to my patch folder into ACPI. Thanks in advanced. PD. Attached my current debug report after apply your suggestions. debug_12545.zip Link to comment Share on other sites More sharing options...
lubeats Posted November 24, 2017 Author Share Posted November 24, 2017 Hi Hervé, I enabled Load VBIOS because kextsToPatch didn't work and I saw in a video on YouTube and in that moment I get VRAM in system but with blinking graphic. Some suggestion? Thanks in advanced. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 24, 2017 Moderators Share Posted November 24, 2017 Boot to Clover GUI, hit F4 on the keyboard. This will extract the raw DSDT/SSDT Compress and attach /EFI/Clover/ACPI/Origin here Also post your system's spec Does it have Optimus or just HD graphics....
