Thank you, Herve and Bronxteck. I will try both SMBIOS for M4600 and external monitor. I will also search for those forum discussions for M4800. I will let you know the results. Have a nice weekend, David

Thank you, Bronxteck. The dsdt.aml was for Latitude E6440. The first picture was taken after I removed dsdt.aml, and without loading cache and kext. This laptop PC has only three USB-3 ports and do not have any USB-2 ports. Could that be the problem? Thank you, David

Thank you, Herve and Jake. Without -xcpm in the boot command, the LCD monitor is black, and USB does not have any activity (no LED lights flashing). With -xcpm and without load cache and kext, the LCD monitor has following error if I removed dsdt.aml (The first picture). The USB has some activities for about a few seconds. Thanks again and have a nice weekend.

I have a Toshiba Tecra W50-A and try to follow Dell Latitude / Inspiron El Capitan Clover Guide at https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-el-capitan-clover-guide/. However, I got error when I try to boot USB. CPU - Intel® Core i7-4810MQ 2.80GHz (Haswell I guess) Please help. Thank you. David

Thank you, Jake. My Dell Latitude e6530 Mavericks with Chameleon uses HDMI video with Nvidia card and without sleep capability (everything else works). So, I will jump into Yosemite with Clover. Please let me know where I can find the guide. Thank you very much. David

Which external display port does not work, VGA or HDMI? Thanks.

Thank you both Jake and Herve for your excellent knowledge and very quick reply. Yes, I see all 8 cpu in the Activity Monitor now. Thanks. However, I can see that cpu 1, 3, 5, 7 are much busy while cpu 2, 4, 6, 8 are less busy. Please see attached picture. I guess that some applications are not able to see 8 cpu, but see 4 cpu. Please kindly advice where I can download Kozlek's FakeSMC kexts for i7-3720QM 2.6GHz processors. Thank you and have a nice evening. David

Hi Jake, I just noticed that both ML and Mavericks only use half of 8 CPUs in Latitude E6530. Please see attached Mac system info picture which says only 1 processor and total 4 Cores, compared with the Windows picture which has total 8 CPUs. Please kindly advice how to fix this. Thank you and much appreciated. David

Thank you, Jake. It works great. Have a nice weekend,

If possible, please send me patched DSDT SSDT files of OSX 10.8 mountain lion for DELL Latitude E6530 with "Intel® Core i7-3720QM CPU @ 2.60GHz" which has "NVIDIA NVS 5200M" and "Intel® HD4000" GPUs. I unchecked Optimus in BIOS version A12. And now Windows 7 Device Manager does not show Intel HD4000 GPU any more. I will buy DW1510b to replace "Intel® Centrino® Wireless Bluetooth® + High Speed Devices". Thank you very much.
