known problem
Delete EHCI (EHC1 / EHC2) completely from the DSDT.
OSX configures it very well alone with USBInjextAll.kext in /other and then the USB flash drive boots without problems.

I did manage to install sierra 10.12.6 but no audio, gpu = 7mb and lan connection :((

maybe i got confused what files goes to where. even my kext is messed up and when i load dsdt it doesnt boot up.

please check my config and advise or edit.

 

these 3 kexts is the only kext on my "Others" folder. Nothing on 10.12 Folder.

Post the whole EFI/CLOVER folder please.

Your config.plist is not the one provided in the OP (tonyxxx :o)!!!

Start from scratch and read carefully the Guide.

Ive tried following the steps here for 3 days but to no success :(( Tried all clover versions but they just dont work with me.

 

I havent added anything yet. I tried the config.plist here but then it doesnt boot.

 

Im still a newbie looking to understand more how this works.

So it's not an issue when installing Clover but rather an issue when trying to boot. And this is not surprising regarding the CLOVER folder you were using. It is obvious that you didn't follow every step in the Guide otherwise you should have able to boot to the installer.

 

Anyway, try mine and report back.

Try another USB port.

Or another USB pen (USB 2 if possible).

 

the error appeared while booting your clover folder.

I dont understand. Do you want me to reinstall sierra again? Ive tried before all usb ports/4 usb thumb drive but as ive said the all downloadable clover version gives me the same error. I reverted to the last attached clover. Only issue now is the sound and hd5450 not working.

Ok i had time today and made another usb installer with attached clover. Used Clover_v2.4k_r4972.

Below is the Clover Config.

 

Wish me luck and will update later once done.

 

Followed the Optiplex 760-780 files in the Forum for my Optiplex 960.

Hello Poly. Thanks a lot for your kind replies. Ive managed to install everything.

 

Just wanna ask, can i update the security patch directly from app store?

  • 7 months later...

Successfully upgraded my Dell Optiplex 990 spf to Mojave 10.14.6

Only as feedback if somebody search if it's possible.

 

But the next upgrade is available... 10.15.3 (Catalina). Does anybody tried this at the Optiplex successfully?

OK, 10.15.3 seems not to work. If I start the installer after reboot, I see the apple-logo and some steps of the Progress-Bar. But then the PC reboot automatically.
Evern booting with "-v" doesn't show usable messages what the cause of this.
Any Ideas?
