Hello. I'm trying to install Mojave on my ThinkPad T420S using the Olarila Mojave image but I'm getting a message "This version of macos 10.14.3 cannot be installed on this computer". Previous versions (High Sierra) installed successfully. Can this be fixed using Clover changes, or by a Mojave Patcher? Please help. Thank you. Added in 45 minutes 3 seconds: Solved it. I used iMac 18,3 for SMBIOS.

I got the slider (brightness control) working using the DSDT edit. But the maximum brightness from the slider isn't my display's max brightness, still low for me.

Finally, I got a working DSDT without the need of a motherboard-specific/compatible patched file. Thanks for this forum for inputs, especially oldnapalm. Below are the steps I used and might help others. Please correct me for mistakes or let me know if it shouldn't be here. A. Prepare a clean DSDT 1. Run a DSDT Editor on Windows 7 (of course, Windows version of DSDT Editor is used). 2. Then on File -> Extract DSDT. 3. On IASL -> Compile. Here I got 17 errors. 4. Click "Fix errors" button. I now have 0 errors, 3 warnings, 1 remark. Although I have compiled DSDT now. I decided to try to fix the Warnings and Remarks. For warnings which is just ("Not all control paths return a value...", I just added this statement at the end of erroring method: "Return (Zero)". 5. For the Remark message ("Use of compiler reserved name (_T_0), on Patch -> Open, I then browse "_T_x rename.txt" under "/Patches" folder which is included in the DSDT Editor package. Click "Apply" button. 6. Compile again and now it's all clean. B. Apply a patch 1. A method (or function) that's always been called by almost all patches should be added to DSDT. It's called "DTGP". If it's not present, you'll get "Object does not exist (DTGP)" error. To do this, on Patch -> Open, and then browse to "DTGP.txt". Click "Apply" button again. 2. Now, copy an existing patch from here (http://Olarila.com/forum/viewtopic.php?f=19&t=634) or from an existing DSDT.aml that contains the patch you need. 3. Compile again. 4. If no errors are found, on IASL -> Save AML as... and save it with filename "DSDT.aml" on location accessible when you boot on Mac. 5. Boot to your hackintosh (Mac) now. Copy the "DSDT.aml" you saved to "/Extra" folder. 6. Reboot. That's it.

Thank you. Some comments on the following: For some laptops (I know of some Samsung) you can't fix errors or it won't boot, so you need to use older version or run IASL from command line (it will create AML even if there are errors). -you mean older version of DSDT Editor? In running IASL from command line, DSDT Editor is still the tool to use? You may also have made some mistake, like saving DSL (source) instead of AML (binary). -On DSDT Editor, I click on "Save AML as..." then save it on desktop, then install it using multishit. Is this the proper way. Just extract and compile (fixing errors or not) won't make a difference. If you don't make any changes, it's the same as if you don't have a dsdt.aml at all. -This is correct. But my goal here is to have a working patched DSDT first which can I edit incrementally.

Hi. My laptop (ThinkPad T420s) is not on your DSDT list. Is it possible for me to create my own patched DSDT? I tried creating my own base DSDT.Using DSDT Editor app, Extract DSDT, compiled it, then Fix errors button, then installed it with multishit. When I rebooted my laptop, it now freezes. Is there a minimum required code change or patch for it to work?

Thank you. It seems I have to do DSDT edit which I tried to avoid.

Hi. I go the Intel HD 3000 graphics card working. But my problem is that it's brightness is very low. I want to adjust it but there's no option on Displays preferences. I also tried the suggested keyboard keys but nothing's worked for me. I installed the "Shades-universal" app but the max brightness on the slider is my current low brightness. I can get the full brightness by putting Mac on sleep then wake it up.

Hi artur-pt. Thank you very much for this link. It worked like magic on my Intel HD 3000 card.

Hi oldnapalm. Still no luck on the nVidia card. But I am very happy I was able to make the Intel HD 3000 work with full acceleration using the link provided by artur-pt. The key is the "device-properties" and hex string. If only I know how to produce the similar device-properties.hex for the nvidia, I can also make it to work. Still, thank you very much to you.

I'll give it a try tomorrow. Already 2:30 here, OpenGL test was on Mountain Lion but using 4.00 app as I can't access Mac app yet for the latest version. Thanks in advance.

No, I can't see it. Only "Apple Software Renderer" is present. Maybe it's with OpenGL. Is there a kext for this. I am comparing my graphics properties with a Dell with with exact graphics card. Mine on ROM Revision says "preset 1.0.0" while on Dell is "NVIDIA Quadro NVS 4200M OpenGL Engine". Sorry to bother you. I might give up on this card and work back on Intel HD 3000. Thank you very much for your help.

The AGPM trick didn't work for me. This is my procedure. Copy "AppleGraphicsPowerManagement from ../Extensions folder to desktop. Edit the content of info.plist by finding a MacBookPro6.1 key, then replace with my graphics' vendorID/deviceID. I then installed the modified kext, then change my SMBIOS to MacBookPro6.1. Am I missing something here?

Yes it worked for Lion using discrete graphics and gf100hal. NVDAGF100Hal and NVDAResman are loaded as shown on Extensions on System Report. Sorry, what is AGPM?

Through BIOS. I can choose between "Discrete graphics", "Integrated graphics" and "NVIDIA Optimus".

Thank you. Sad to hear that. My nVidia card used to work on Lion and I didn't know it won't on Mountain Lion. I'll give another try for Intel HD 3000 using the link you gave.
