Moderators Jake Lo Posted July 27, 2014 Moderators Share Posted July 27, 2014 Recently got a hold of an Optiplex 990. Saw a few threads here regarding this model but no guide or bootpack in any of them, so I decided to write one up. An easy build as mentioned by Dan Marshall, runs really smooth. It comes with an AMD HD5450, didn't try the built-in Intel HD2000. Credits: Conti - for myHack Slice - latest VoodooHDA 2.8.6 Dr. Hurt from Insanelymac - patch DSDT for HD5450M Specs: i5 - 2400 3.1GHz | 8GB ram | HD2000/AMD HD 5450M | 128GB SSD | Mountion Lion 10.8.5 | Mavericks 10.9.4 | BIOS A18 Build USB Installer with myHack Download and Extract bootpackExtra.zip Relaunch myHack, select Install Extra, select USB Installer as target drive. Select "Use my Own" and browse to Extra above Boot with USB Installer ( Make sure to plug monitor to DVI, vga is not supported) Format disk to GUID and Extended Journal and start the build When prompt, select "Use My Own" and point to Extra on USB Installer When prompt to remove problematic kexts, select Yes, Yes, No Wait a few minutes, system will automatically reboot, remove the USB Installer Complete the installation Done. Working: AMD HD 5450 Full QE/CI Dual Display Sleep/Shutdown/Restart LAN Audio using VoodooHDA 2.8.6 Note: Make sure to set SATA Operation to AHCI. For best result, set it to the Default, apply and then set SATA Operation to AHCI. /!\ For Mountain Lion install, remove AppleKextExcludeList.kext from bootpack /!\ For Yosemite Install, see guide here and boot pack posted here 1 Link to comment Share on other sites More sharing options...
