sebus

Thanks, but same issue as booting without any .aml files using El Capitan Unsupported Chip

Many thanks for this Jake Lo. File attached sebus origin.zip

Yes, I have, did not work either But I do not have enough knowledge regarding the subject to be able to figure it out myself, what and if from Clover options could make it work. I was hoping that being rather popular business desktop, somebody would have tried it previously & maybe have had a success sebus

Of course I am NOT using DSDT pack from a different hardware! (why would I? it would make no sense!) OP 3020 is bog standard machine, not some unknown home build, so getting the specs is rather easy: here Intel® Coreâ„¢ i5-4590 Processor Realtek RTL8168/8111 Realtek HD ALC280 Intel® 8 Series/C220 Series

Ofcourse I am trying to boot with Clover (how otherwise?). Stock kernel (why to patch?) I never crashes, but never goes beyond this point Tried with onboard video & with nVidia 210

I see that there is pack for 9020 here But did anybody manage to install OS X on Optiplex 3020? I did not even manage to boot it to install screen (using any version Yosemite USB) Thanks sebus
