Hey @Hervé I told You that info in my post in InsanelyMac here. I discovered it for curiosity in a config.plist where nobody mention that with it We could get output video port for DVI and HDMI. It works in mojave beta too but audio HDMI doesn't works.
Thanks @Jake Lo. Now I got NVRAM to 2448 MB. My friend, maybe Could You help with this fix ?
Hi @gelomon tell me, how did You increase your VRAM for your Intel HD 5500, I have the same graphics card. Please tell me how you did it.

I want to know How to remap my keyboard to brightness control keys. I have a Lenovo Z70-80 laptop with Core i7-5500 and my graphics card is Intel HD Graphics 5500 running macOS HS 10.13.6 I followed the RebahMan Guide Patching DSDT/SSDT for LAPTOP backlight control and in a special part it says that if the VoodooPS2Controller.kext doesn't works correctly with your own keyboard We can custom it. Then, I follow the next steps: Determining EC query methods: - install ACPIDebug.kext: https://github.com/RehabMan/OS-X-ACPI-Debug - I installed on S/L/E - add the ACPIDebug repo to MaciASL "Sources" per README - It is on sources by default - apply ""Add DSDT Debug Methods" - I added this to my DSDT - apply "Instrument EC Queries" - I added this to my DSDT - I added debug.txt too - In Readme debug says 3 steps, but this final step: Third, add code to your DSDT to where you wish to cause trace messages to system.log (call \RMDT.PUSH). - I don't understand this part or what code I should add. Please I need support with this special part. - I added additionally ioio binary file to /usr/bin/ , like it says in the guide - reboot - monitor system.log as you press your brightness keys After I reboot I pressed all FN keys, one by one and with combinations with Fn+ key but nothing. My DSDT. aml patched file is in /Clover/ACPI/patched and like it says in guide the system.log is created in root, I can understand is the same folder where is my DSDT, after pressed the keys. It doesn't appear anything file. I don't know maybe I made a mistake in the process. PD. 01- I attached my DSDT patched. 02. I get some keys code with the app KeyCodes running over macOS and I tried the same with my microsoft keyboard in my hackintosh Pc and codes are the same. I attached all pictures about it. Please help me with the solution. Thanks in advance Finally I solved my issue here
I want to know How to get the VGA and HDMI output on the Lenovo Z70-80 laptop with Core i7-5500, my graphics card is Intel HD Graphics 5500 with macOS HS 10.13.6 I read several guides to do it, but it's for Intel HD Graphics 3000 and I tried to do it for my graphics card, looking for similar values and replace them. Where we should patch the AppleIntelSNBGraphicsFB.kext file A few small examples are here 01 02 03 In another site I found a different file to patch that is AppleIntelFramebufferCapri.kext, and I searched and replaced the values and tried it with my macOS but nothing. This guide here And finally I tried this KextsToPatch in my config.plist file Name: AppleIntelSNBGraphicsFB Find: 01020400100700001007000005030000020000003000000002020500000004000007000000030400000004000009000000040600000004000009000000 Replace: 01020300100700001007000005030000020000003000000006020000020000003000000002050000000800000700000000000000000000000000000000 commentary: HDMI + VGA But nothing again ... In my long adventure to try to make it work, I found different config.plist files to fix the functionality of my Intel HD 5500 graphics card, and I tried differents KextToPatch values, and with a bit of luck I found these values Name: com.apple.driver.AppleGraphicsDevicePolicy Search: BA050000 00 Replace: BA000000 00 Comment: prevent AGDP from loading With the above values I can sync VGA & HDMI output automatically VGA: In my ViewSonic VX1945wm with 1440 x 900 res HDMI: In Samsung TV UN32EH4500G with 1366 x 768 res (the worse resolution) and when I try to change to full HD I can but it has unfocused image, out of frame and with sound without volume control. My TV is full HD native. Please I need support from someone who could help me to fix this. Thanks in advance. PD. I attached my config.plist file and pictures config.plist.zip I solved my issue here
HI Tosol, I'm Luis and I want to request your help to solve issues with my Lenovo Z70-80
I got two problems on HS 10.13.6
- Brightness control keys
- Output signal VGA & HDMI port
I read your post
I read your post and I want to know how can you remap key to brightness control, I have brightness slider on SystemPref/Display
I have a Lenovo Z70-80 laptop with Core i7-5500 and my graphics card is Intel HD Graphics 5500
I follow the rehabman guide to remap keys ...
I followed this steps:
Determining EC query methods:
- install ACPIDebug.kext: https://github.com/RehabMan/OS-X-ACPI-Debug - I installed on S/L/E
- add the ACPIDebug repo to MaciASL "Sources" per README - It is on sources by default
- apply ""Add DSDT Debug Methods" - I added this to my DSDT
- apply "Instrument EC Queries" - I added this to my DSDT
- I added debug.txt too
- In Readme debug says 3 steps, but this final step:
Third, add code to your DSDT to where you wish to cause trace messages to system.log (call \RMDT.PUSH). - I don't understand this part or what code I should add. Please your support.
- I added additionally ioio binary file to /usr/bin/ , like it says in the guide
- monitor system.log as you press your brightness keys
After I reboot I pressed all FN keys, one by one and with combinations with Fn+ key but nothing.
My DSDT. aml patched file is in /Clover/ACPI/patched and like it says in guide the system.log is created in root I can understand is the same folder where is my DSDT, after pressed the keys It doesn't appear anything file
I don't know maybe I made a mistake in the process

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.
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
Hi Bronxteck, continue with the same issue after the change your suggestion.
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
