[SUCCESS]Dell Optiplex 9020 micro El Capitan / High Sierra

Recommended Posts

Installation and post installation went smoothly without errors, I'm quite happy :D thanks to you @Jake Lo. some issues I've encountered though:
1. audio device is not detected 

2. When I insert my passport or any other usb device this message pops up "usb device needs power..." but seems to work when I restart the system with the devices connected

I've been wondering about all those fixes in the Clover ACPI config. And there are incorrect settings activated too like Generate P States + Generate C States.

 

I've not seen any extracted or patched DSDT in the Clover folder. Maybe your ought to check the power values displayed  for your USB ports in IOReg and then compare them to iMac15,1's arrangements. You may then patch the EHCx and XHC controllers accordingly like it's done on laptops.

 

These are the power settings of the USB3 XHC device on the iMac15,1:

                        "AAPL,current-available", 
                        0x0834, 
                        "AAPL,current-extra", 
                        0x0C1C, 
                        "AAPL,current-extra-in-sleep", 
                        0x0C1C, 
                        "AAPL,max-port-current-in-sleep", 
                        0x0834, 
                        Buffer (0x01)
                        {
                             0x00                                           
                        }

Thanks. But what I did was reinstall and everything seems to be working well now. Some minor issues though, I still couldn't get sound from the onboard audio but at least now I could use HDMI audio. But I'm quite happy, this is my first build so thanks again @Jake Lo for the guide and helping me fix installation issues.

Oh, I thought you decided to install El Capitan because you don't want to encounter the sleeping issue with High Sierra.

If you don't know already, waking from sleep causes system to reboot.

Last know OS to have working sleep/wake is Sierra.
