Not open for further replies.
Hi guys, I have made a successful installation on T5810(E5-1650v3, rx560 & 4*32g ram) with 10.13.6. But still can not install 10.15.
I will post my EFI file here for someone with the same setttings.
One issue that I met is the RAM error. It could be fix by trying different bios versions.
By the way, if you guys could install the 10.15, please let me know.
Thanks.

Now, I can install 10.15. It works fine, but there is something wrong with the bluetooth(BCM943602CS).
I will post my EFI here, and update if I could fix this problem.

Thanks for sharing it mate. Excuse me, what BIOS version and settings are you running? And do you think this EFI is compatible with Mojave? Thanks!


UPDATE: Using the @Simontt EFI (thanks again), I was able to install Mojave 10.4.6, using clover 4961 and BIOS A33. Only problem I got is very slow and unresponsive macOS at first time boot, is this normal? and, second problem was that I copied the entire EFI folder to the EFI partition on my SSD (is this ok?) and at reboot I can only reach the Login Screen with a "ghosted" apple logo and mouse cursor.

I don't know what to do now, any help would be appreciated, thanks folks!

Hi Folks,

I was able to get Catalina installed on my the Dell precision T5810 workstation with a Xeon E5-1603v3 cpu and Hd7950 graphics card.

For audio (including internal speakers to work), I had to use ALCID=16 in the boot args.
For the HD7950, I had to use npci=0x2000 in the boot args.

Attached is my working Opencore 5.8 EFI for the T5810 with the E5-1603v3 cpu. Hope this helps.

P.S. recently I updated the proc to a Xeon E5-2620v3 cpu and the system halt on boot (still working on that issue). There must be something very different between the E5-1603v3 proc and the E5-2603v3 proc.

Hi hackieMac! Again thanks for sharing your efi folder. I am wondering to know, if you could tell me the instructions you followed to opencore method. I dont undertand it at all, please. And... I dont know but, if I am right, I could copy your EFI folder to my EFI partition and it will work? Thank you very much

you almost finished.
you should put the whole EFI folder into EFI disk part.

By the way, I cannot install the os without A09 bios version. and I don't know why~
one problem that I met is that the system will be very slow (like the screen frozen) when I open some windows.
and it was not caused by rx560. I have changed it to rx5500xt, the problem is still here.

Best.

Thank you a lot!! Going to try A09 then. And keep you posted if with the RX580 the problem persist. Greetings!


UPDATE: with BIOS A09, reached installer with no problems, but at first boot Im stucked at Apple logo + mouse cursor after the verbose output. Any help would be aoreciated as always. Greetings!

I still met the problem. it may caused by USB or CPU.
when the screen frozen, Apple Music which plays based on a usb Bluetooth crashed too.
sigh.
 
Hi. I have a problem with the screen glitch. My video - powercolor RX570 4G. what could it be?
