  1. I also use E6540 and this is what I've got so far. config.zip kexts.zip patched.zip What works: CPU frequency adjustment(though SSDT.aml,so if it does not suit for your CPU, remove it and put your own SSDT.aml back into the right folder), HD4600, AMD 8790M disabled, sleep(by system menu only), touchpad, SD card reader, USB, camera, internal speakers, internal mic, HDMI video output,Ethernet, brightness adjustment(by system menu only),battery and AC status What doesn't work: AR9285 wifi (cause Apple removed the related driver in Mojave), sleep by closing the lid, brightness and volume adjustment by hitting the keyboard fastkeys, HDMI audio output To hansimglück2: As far as I know, there're two sub-type of Latitude E6540, the early sub-type and the late sub-type. Dell use lvds-40pin LCD panels in sub-type E6540 first and changed to edp-30pin LCD panels in the late sub-type E6540 intead. So the motherboard of the early and the late sub-type are not the same. BTW: Mine E6540 has some strange problems. When I press Ctrl + Alt + Del under DOS or BIOS settings, the E6540 just shut down and refuse to reboot. The AMD 8790M graphics also causes auto-shutdown problems in Windows 7 32bit (after AMD graphics driver installed) or some Linux based system (such as Ubuntu). Before the auto-shutdown the fan will run very fast and make quite a noise. After the auto shut-down, I can find "critical tempreture shutdown" logged in the BIOS.This problem gave me quite a lot of hard times when I tried to disable the AMD 8790M(cause when it's disabled the E6540 always auto-shtudown and finally some other guy helped me disabled 8790M successfully) So mine E6540 is the early sub-type and I wonder what's yours. Do you have the same problems? To Jake Lo: Could you help to fix the HDMI audio output and the fastkey problems? I'm not a native English speaker so sorry for my poor English.
  2. UPDATE: The reason seems to be the SSD. I used an OEM version Intel 520 and I also tried Intel 525, the HDMI output didn't work. But it worked after I install the system into an Intel X25-M or a Sandisk SSD PLUS. Since the both Intel 520 and 525 is based on SandForce 2281 chip ( while Intel X25-M and Sandisk SSD PLUS is not ), is it possible that there're some compatibility problems for SandForce 2281 SSDs?
  3. Do you mean the SMbios profile in the clover config.plist ? I didn't change that. With the same config the SSD and APFS breaks HDMI output but and HDD and HFS+ didn't.
  4. However for SSD even I disabled TRIM in clover patch I still can't get HDMI output back. Is there something I can do ? Or I have to wait Apple fix this ?
  5. I think the config.plist and the dsdt should be OK cause the HDMI output works under some circumstances. I tried many times and found some strange results. HS system installed into SSD,APFS partition.--- NO HDMI output. HS system installed into SSD,HFS+ partition.--- NO HDMI output and the system partition will be transfered into APFS automatically. HS system installed into HDD,HFS+ partition.--- HDMI output works. I also get the HDMI output under APFS,SSD for one or two times but I don't know why I get that. Also, I found that even I get HDMI output under APFS,SSD. Once I enable trim though colver---Kext to patch. The HDMI output disappears.
  6. And here is the IOreg record. AW-M17X-R4's MacBook Pro.zip
  7. Neither audio nor video works. And I can't see "Intel HDMI audio" in System Report --- Audio.
  8. My laptop is AW M17X R4 , i7-3610QM, HD4000 + AMD 7970M(disabled). The HDMI output worked in 10.11 but failed after 10.13 High Sierra installed. Here are the DSDT,SSDT and config.plist patched.zip Here are the kext. Other.zip So could someone tell me what's the reason? UPDATE: The reason seems to be the SSD. I used an OEM version Intel 520 and I also tried Intel 525, the HDMI output didn't work. But it worked after I install the system into an Intel X25-M or a Sandisk SSD PLUS. Since the both Intel 520 and 525 is based on SandForce 2281 chip ( while Intel X25-M and Sandisk SSD PLUS is not ), is it possible that there're some compatibility problems for SandForce 2281 SSDs?
  9. I've tried these days and I assume that since the fan speed will get high before auto shutdown the reason could be related to power management or CPU. So I checked the console and found that these codes would show up before auto shutdown. Process launched [1] disabling system-wide I/O Throttling Process launched [1] disabling system-wide CPU Throttling So do you know what is the mistake?
  10. I've tried this and the discrete graphics remained in the SysProfiler. I checked SSDT-8 and I didn't find the _OFF code. What did you do to disable the discrete graphics? And when I try to disable it by adding _OFF into SSDT-8 _INI. The whole process is: SSDT-8 _INI----_OFF code----SSDT-9 _OFF---SSDT-8 SGOF So it is the SGOF code that actually disables the 8790M. However once the SGOF code is applied the auto shutdown problem will come. I think the auto shutdown problem is something about power management and the SGOF code might call to some code related to EC. But I'm not a professional programmer and I can't dig up about this. Could you check the code and try?
  11. Ok, I'll try it as soon as I get home.BTW,Do you have E6540?And if yes,does it contains AMD 8790M? And I'm curious that how did you make the discrete graphics "invincible".(If I used your DSDT,the discrete graphics is still there even I add the disable code to SSDT-8.)
  12. I know this laptop (E6540) have 2 versions. The early version used LVDS screens. However the haswell don't support LVDS so Dell used a eDP to LVDS chip to transfer the eDP signal to LVDS. And the late version used eDP screens. So they don't need the transfer chip anymore. The screen just get signal from haswell cpu. My laptop is the early version and it has the eDP to LVDS transfer chip. Is it possible that this is the reason? And I'm eager to find out how to make it not register in SysProfiler.
  13. I read your post of e6440 and according to the picture you uploaded you disabled the discrete graphics in OS X 10.10,however there's no graphics related SSDTs in your boot pack,how did you do that?Did you disable 8690m though DSDT?Also I found that before auto shutdown I always get the following information in console. Failed to connect (_consoleX) outlet from (NSApplication) to (ConsoleX): missing setter or instance variable Could you think of something?
  14. A16 bios. And I think I've trimmed the clover config.plist as simple as I can. Could you upload your config.plist? I'll try them next week (I am traveling outside now and l didn't bring the laptop with me.)
  15. If I keep all the things original, the discrete graphics can not be disabled.
  16. Tried in your way, auto shutdown again. patched.zip Here are DSDT & SSDTs.
  17. I tried the similar way, it did disabled the 8790m but the OS X will get high fan speed and auto shutdown. Did you try this on your E6440? Is it successful?
  18. I've got a Latitude E6540 with Intel HD4600 + AMD 8790M graphics and I've been trying to disable the AMD 8790M. I've tried for about 2 weeks and once I disable it, the OS X will get high fan speed and auto shut down. So please take a look at it. origin.zip This is the zip file of original DSDT and SSDTs extracted from clover---F4 key.
