    [SUCCESS] Dell Precision T5500 - Quadro4000|Xeon X5680 (MacOS10.12.X)

    Hi, I have not idea about the AMD graphics card. I used an Nvidia GTX 960. It could need more settings for your video card. Maybe, you can try to use the lastest Whatevergreen and Lilu. I remembered that there is a setting item is called "radpg=15" which under the Boot menu of Clover. You can...

    [SUCCESS] Dell Precision T5500 - Quadro4000|Xeon X5680 (MacOS10.12.X)

    I made some adjustments to my system. Right now, everything works perfectly. I deleted Dsdt.aml in clover and added SSDT-LPC.aml which comes from sebus(thank you so much!), also selected some items in config.plist. I used a Macpro 5.1 as my smbios, the CPU power management works like a champion...

    Hi Sebus, Thank you for your files. I have a question about one kext which you used in your Clover- SMIMonitor.kect. Is it for detecting Fan speed? And how many Fans can be detected in your system? For my system, I only detected one CPU fan and one for GPU. I know there are two 12* 12 cm system...

    Great! I found that you are using NullCPUPowerManagement.kext, so I am wondering whether the CPU frequency still works well or it's locked at the max frequency.

    That sounds awesome. If you need some resources, please let me know. So far as I know, you are the first one who installed Catalina on the Dell T5500. Please keep update and wait for hearing more news from you. About sound drivers(appleHDA.kext ), probably, you need to roll back to 10.13.3.

    FX 3800 has some issues about black screen during booting. If you still have same problem after getting rid of all graphics injection, you may try to use GTS450 instead. If you have a system with Nvidia webdriver pre-installed, Fx 3800 should be good. I am not an exporter. So, I attached my...

    You do better to disable any kinds of graphics kexts' injection in clover. If you have already succeeded to boot up, you can do some research based on your video card whatever is An AMD or an Nvidia card. some cards are natively supported, that could be easy and you may not need lots of work...

    You need to active bootflag '-v' in clover. Then we may know what has happened. I assume that is related to some graphics card's issues from your post images.

    I have an Nvidia graphics card GTX 960 with 10.13.6. It works fine. I attached my EFI below. I tried to use appleHDA instead of voodooHDA. Unfortunately, It didn't work. I can see the sound device as well as the sound control bar. No sound comes out. I don't know the reason.

    Dell Precision T7500 with RX 580!!! White Screen!!! Please Help!!!

    Did you use AppleALC for sound? I couldn't get the native AppleHDA working properly. I used VoodooHDA instead, but the native power management works fine. I can see the fan speed in HWmonitor.

    I am working on Dell Precision t7500 with dual x5675. The graphics card is NVidia gt635. Everything works properly except the audio chip Ad1984a, so I used VoodooHDA instead. I attached my EFI folder below. The worked features are native power management, shutdown function, restart function, and...
