Here also 10.13.4 DP Beta5 17E182a  works on 780.
Again rollback of the AppleHDA of 10.13.3. I still have to do research for the audio problem.

no issue AppleALC here for the Optiplex 790

Yes, all devices work well. Only Dell780 with AD1984A not since beta's ... 4.
I can not find a mistake.
Rollback of the AppleHDA of 10.13.3 and Lilu + AppleALC works well.
Original AppleHDA's of the beta's and Lilu + AppleALC only works with HDMI audio.
Something has changed in the AppleHDA's for analog devices.
790 has ALC269 - no problem
my ALC888 also no problems
only AD1984A has problems with new AppleHDA

Edit:
All set like's are no longer there with the new forum software. So again...

I just updated my Optiplex 755 (AD1984) to 10.13.4 DP5.
No issues with sound whatsoever, no need to do a AppleHDA rollback.

I started with an Optiplex 760 a few years back, I think it was with Mountain Lion. Then I got an Optiplex 780, which is not a whole lot different, I think maybe just the chipset.

Now I have an Optiplex 790, and 990, and I would highly recommend to anyone just starting out to get a 790 or 990. 

With 790 SFF i5 cores going on eBay for about $110 US, I wouldn't be considering the older models myself. 

That's just my opinion. One thing to keep your older 755, 760 and 780's going, and maybe another if your just starting out.

Just a matter of personal choice, but I sold both my 780's and upgraded.

It's nice to have a little more CPU Power, and to not have to worry about rolling back kexts. :)

I totally agree with you, last week I buy another Dell Optiplex 790 with a CPU i3 2100 3.10Ghz, I buy it with only the CPU and nothing else I had for $ 60 Can. I use it for my Beta test and to do that I put my GeForce GT 1030 + 8 gig Ram Corsaire I am very happy now to have two Dell Optiplex. 790

For me this PC is the best compatible MacOS computer because you can run 10.6 to 10. 13 with a compatible Graphics card, What other computer can claim to be able to do this and have the same power as old iMac or Mac Pro :thumbsup_anim:

My 790 has an i7 Core CPU, and I think I paid about $190 for that almost 2 years ago now. The HD5450 Graphics card was $20 after a $10 rebate. Throw in a Solid State Hard Drive, a nice 27" Monitor, and, according to a couple of my buddies, its every bit as functional as their iMacs. :)

I have about $450 in my 790 i7 Core, but wiithout the SSD, and getting the i5 core, which is still a fast CPU, you could put one together for about $300 - $350,  and thats including a decent monitor.

You can't beat that. :)

@morpheousman If I look at my sytems...

Optiplex 755

Spoiler

Stock specifications:
Core2Duo E6750
2GB RAM, 250GB HDD
No PCI GPU
Costs: $30

Upgrades:

  • CPU: $50
  • GPU: $45
  • RAM: $40
  • SSD: $60
  • WiFi: $20

Current specifications:

Core2Quad Q9550
8GB RAM, 128GB SSD
GT 710 GPU

Totals $245

Optiplex 790

Spoiler

Stock specifications:
Core i5-2400
4GB RAM, 320GB HDD
No PCI-E GPU
Costs: $160

Upgrades:

  • CPU: $60
  • GPU: $45
  • RAM: $30
  • SSD: $60
  • WiFi: $50

Current specifications:
Core i5-2500K
16GB RAM, 256GB SSD
GT 710 GPU

totals: $405

But in theory, it'd only have needed the GPU in order to run macOS,
so $220 total

But pushing an older system, like the 755, 760 and 780 to it's limits has its charms.
The 755 still runs very well on High Sierra, albeit a little slower than the 790 (obviously)

For new users is definitely a 790 or 990 better and more modern. Your arguments are good.
Not relevant to me. I have so many computers, MacPro, iMac ...
I have the 780 only for beta testing, I do not use it anymore.
However, it is fun to see how far it still works.

First of all thanks for the nice howto and all the hints.

I had some troubles installing High Sierra on my 780. With High Sierra I received the "OSInstall.mpkg damaged" error, with Sierra I had the "no signal/black screen" problem. Finally I removed my graphics card and install Sierra by using onboard graphics, which was good enough. After installing I updated directly to High Sierra without problems, inserted again my GT710 and it just worked. It could be a useful hint for beginners that struggle an NVIDIA card like I did ;-)

I also got working an Realtek 8191SU USB WLAN Dongle, a Creative USB sound card and a Bluetooth dongle.

The only thing that does not work is sleep and wake. If I send it to sleep the monitor goes black but the box keeps running. After a time I can hear that the HDD stops as well, but the box still runs. And of course I cannot wake it anymore.

Do you have any idea how I could fix this? Boot time is quite long but it would not bother me if sleep/wake worked.

Thanks in advance

Thanks for the quick reply. I'm on HDMI as well and don't inject anything. 
Is it possible that it's because of the patched DSDT.aml I took from the howto? 
I mean that one: 

Quote

my_DSDT.aml.zip (my DSDT, optimized for Core2Quad, configured for HD5450 and Audio LayoutID 13 (0D) for AppleALC + Lilu. Additionally Framebuffer in the Clover is "Shrike" for the HD 5450)

That DSDT injects the AMD Radeon 5000 series.
Try this:

DSDT.zip

Thanks, I tried your DSDT but it's still the same, it doesn't really want to go to sleep...
Apart from that, I don't know what the reason could be.
Do have any special settings in config.plist? Any special driver installed? I only installed the EmuVariableUefi-64, OsxAptioFixDrv-64 and PartitionDxe-64...
