davey076 Posted January 20, 2017 Share Posted January 20, 2017 Dell Optiplex 790 10.12.2 Tutorial Things you need: - an 8GB usb stick or larger - an other Mac or PC running Mac OS First download the Sierra installer App from the App store. After that download the latest version of Clover here: Clover Bootloader Download Diskmaker X from here http://diskmakerx.com Open Diskmaker X with your usb stick plugged in to your computer. Follow the steps and create a bootable Sierra usb stick. After that open the clover installer and select the settings from above. Select the usb stick as the target disk. After the installer is done, the EFI partition will be mounted on the desktop. Copy the EFI folder from the Optiplex 790 folder downloaded from here: 790_Clover.zip to the root of the EFI drive. After that copy the kexts from /Volumes/EFI/EFI/CLOVER/kexts/10.11 to the other folder. Restart you pc and boot from usb. Select the install partition in Clover. When the installer has loaded go to disk utility and elect the disk you want to install Sierra on. Format the disk to Mac OS Extended (journaled). Close disk utility and proceed the steps in the installer. (make sure you select the correct disk) When the installer is done reboot. When you have an ATI HD5450 you can use the DSDT provided in the 790 folder. If you have an other card follow the steps below. To create a DSDT for your system follow this tutorial (windows is required.) When you've completed that, copy the dsdt to an other usb stick. After that boot into the installer usb and select the drive you've installed Sierra on. Download MacAisl fro here https://sourceforge.net/projects/maciasl/ Rename the DSDT file to DSDT.aml and open the file with MacAiSL. Go to preferences and add this source http://pjalm.com/repos/general Go to patch and select this patch USB - Device Renames for OSX 10.11 Then hit compile. If you get the 4080 error follow this thread https://www.tonymacx86.com/threads/error-4080-when-compiling-dsdt-for-p8h61-mx.97353/ After that install the latest version of Clover with the settings from above on your Sierra drive. The EFI partition will be mounted on your desktop. Copy the DSDT to /Volumes/EFI/EFI/CLOVER/ACPI/patched Download Clover configurator from here: http://mackie100projects.altervista.org/download-clover-configurator/ Mount the EFI Partition from your usb stick using Clover configurator and select the config.plist file. Write down all the settings you find in there and then restart Clover Configurator. Now select the EFI partition from your Sierra disk and select the config.plist on that drive. Copy all the settings you wrote down EXCEPT the Inject ATI setting. Navigate to SMBIOS abd select the magic stick. Select the iMac icon and select iMac 12,2 Save the file and exit When thats done, open the optiplex 790 folder and copy the kexts from the EFI|/CLOVER/kexts folder to your kexts folder on your EFI drive. make sure you put them in the 10.12 folder. After that you can reboot your system without the usb stick and you should be good to go. Google for the right drivers for your specific GPU. When you have the ATI card you can boot into the usb stick and select the drive you've installed Sierra on. When you've reached the desktop, install the latest version of Clover on you Sierra disk. After that copy the kexts from the 790 folder to the kexts/10.12 folder on your EFI drive. Then copy the config.plist from the 790 folder to your EFI drive. And last but not least copy the ACPI folder from the 790 folder to your EFI drive. MAKE SURE YOU OVERWRITE THE FILES WHEN ASKED. Then download Clover Configurator (link above) and mount your EFI disk and select the correct config.plist. Navigate to SMBIOS abd select the magic stick. Select the iMac icon and select iMac 12,2 Save the file and exit Remove the usb drive and reboot and you should be good to go. Sound works with the latest VoodooHDA driver: https://sourceforge.net/projects/voodoohda/ When you want to get native power management for the CPU follow this tutorial: https://www.tonymacx86.com/threads/quick-guide-to-generate-a-ssdt-for-cpu-power-management.177456/ MAKE SURE THAT YOU ALSO RUN THIS PATCH WHEN YOU WANT NATIVE POWER MANAGEMENT: http://www.insanelymac.com/forum/files/file/132-aicpmpatch/ When you're done, you can delete the nullcpupowermanagement kext from the kexts folder on your EFI partition and reboot. This is my first tutorial so i hope you guys can follow it. If you have any questions, feel free to ask. Cheers! 2 Link to comment Share on other sites More sharing options...

morpheousman Posted January 28, 2017 Author Share Posted January 28, 2017 so far I've found nothing that isn't working! Is your native AppleHDA Sound with HDMI working? There is a reason the realtekALC.kext was included in my 790_Clover.zip that you linked to. It's because MacPeet got the native AppleHDA Sound working for the 790 too. If you want the updated version for Sierra, you can find it on Post #1 of MacPeet's 755/760/780/790 Sierra Guide. http://www.insanelymac.com/forum/topic/312656-guide-macos-sierra-1012-dell-optiplex-780-760-755-790/ MacPeet's AppleHDA Sound for Optiplex 790. on_the_fly_Audio_Optiplex790_10.12_Sierra_276_26.zip My Optiplex 790 Sierra Update Done! 1 Link to comment Share on other sites More sharing options...

I don't really have knowledge of kernel thing so i don't know which options to configure Seems like you didn't followed the guide to the letter. Make sure you're using Optiplex 780 (760) El Capitan Clover-v4.zip files from post #1 and that you installed them in the right place. Also, I think you'll need a discrete GFX card. The graphic chip in these Optiplex is definitely not supported by OS X anyway. Also, give more info on that Celeron like model and 64 Bits support.

Wuddle Posted February 9, 2017 Share Posted February 9, 2017 CPU is Intel Celeron 440 Processor (2.0GHz, 512K L2 cache, 800MHz FSB). I followed the normal guide on youtub without patch. I just looking for help here. Optiplex 780 (760) El Capitan Clover-v4.zip doesn't sound like it will work on 755 macOS. I try to get some GFX card Link to comment Share on other sites More sharing options...
jfirth8187 Posted February 24, 2017 Share Posted February 24, 2017 Hi there, I have a Dell 790 with BIOS Revision A18 and I'm struggling to get UEFI to work and boot from, it does not recognise my USB stick "The selected boot device failed". I've tried a couple of different memory sticks and I can only get Legacy to work. On a note Legacy does work and I can install El Capitan using the information on this thread (many thanks to all the contributors), but Sierra is where I'm coming unstuck and I think the problem may be UEFI. Settings: I have no security on the BIOS, UEFI is selected but when I browse to add the USB stick as a bootable device I can't see the USB stick name, just it's subfolders. I've created a boot device for BOOT, EFI (folders). The BIOS posts and reads the memory stick but I get a non bootable device error "The selected boot device failed". The memory stick is formatted GUID, Mac OS Journaled. All folder structure is correct (I think as it'll work if I re-configure for legacy boot). The Dell 790, is the i3 2120 version, 4Gb RAM and works fine with El Capitan, sound, ethernet etc. Hopefully a simple fix for somebody who has better knowledge of the Revision A18 BIOS on the 790's? Thanks all in advance Link to comment Share on other sites More sharing options...

blxkspell Posted June 19, 2017 Share Posted June 19, 2017 what smbios settings can I use? Can I choose random Configurations (like newer years than late 2009?) Link to comment Share on other sites More sharing options...
polyzargone Posted June 19, 2017 Share Posted June 19, 2017 what smbios settings can I use? Can I choose random Configurations (like newer years than late 2009?) Not without some mods. The USB_Injector.kext is specially designed for iMac10,1 models. As an alternative, you can edit the USB_Injector.kext/Contents/info.plist and find/replace any instance of iMac10,1 by the SMBios of your choice. But keep in mind that the SMBios needs to be the closest as possible to the specs of your Optiplex 780 MT and it wouldn't make any sense to choose one that's based on an Haswell architecture for example. 1 Link to comment Share on other sites More sharing options...
blxkspell Posted September 7, 2017 Share Posted September 7, 2017 can i upgrade from 10.11 to 10.12 via the appstore app? or do i have to completely reinstall sierra (erase my current system) Link to comment Share on other sites More sharing options...

blxkspell Posted September 9, 2017 Share Posted September 9, 2017 @macpeet thanks so in fact the only thing I have to do is to copy the /10.11 kexts to 10.12 da ich sehe, dass sie aus deutschland kommen, können si mir auch auf deutsch antworten Link to comment Share on other sites More sharing options...
cmsantiagoiii Posted September 18, 2017 Share Posted September 18, 2017 Updated to Sierra and can get to the machine remotely but it just shows a black screen now when booting. It is not frozen. Any thoughts? Using the latest nvidia drivers. Link to comment Share on other sites More sharing options...
blxkspell Posted September 27, 2017 Share Posted September 27, 2017 I tried to use the Direktupdate app and now ended up in a kernel panic I think. In clover, my ssd renamed from "El Capitan ssd" in something like "install Macos from El Capitan ssd" but when I hit enter I get a black screen. I already tried to boot in safe mode but it didn't work. Verbose mode tells me "uptime in nanoseconds ...." Link to comment Share on other sites More sharing options...

kaptsea Posted October 20, 2017 Share Posted October 20, 2017 Hello people! I had to use the apple lan kexts to get a working network on my 755. When using the intel one, after saturating my network card, I would need to restart to get it working again. Link to comment Share on other sites More sharing options...
