Anyone got osx86 running on a Dell OptiPlex 755 quad yet? I'm about to give it a go.. looking to save myself some time.

Thanks!

hi. i have the same running jas 10.4.8. mines not a quad core though but i guess its the same. Apart from sound and 3d acceleration, works good.

If you have the ati x1300 graphics card DONT select any of the bundled ati graphics drivers at installation, they wont work. I just selected intel sse3 support and loginwindow fix in addition to the preselected essentials software. Graphics worked with only vesa support (no 3d acceleration).

Ive tried in vain to get the sound to work but i dont think anyone has done so on the forums yet.
Instead im just going to get a cheap usb sound adapter like this:

Built in ethernet works without drivers.

My buffalo wirless usb adapter works with drivers.

Hope this helps,
Any more q's, just ask,
Brendan.

Actually, it appears the 755 has an Intel 82566DM nic onboard.. which nobody appears to have gotten to work yet.

Hi bren50c

I have a working on board Audio for the Optiplex 755 . I cannot get the onboard LAN to work.
Can we trade drivers ?

I used the Leo4All driver called Azalia_ADI1988.pkg

thanx in advance

Vince

can we get a link to that please I'm having the same trouble and i have tired so much stuff with no luck i would appreciate it

Hi J.Matt.Harris

So is your onbard Intel Graphics card working ?
If yes , do you have QE/CI working ?

I have a Nvidia card slotted in my PCI X slot.

Mine works but no QE/CI , so my iMovie does not work. To check , goto , "About this Mac" , "More info", "Graphics/Displays" and look ate the Quartz Extreme : entry.

The 755 is a great Hack , it is very silent and can be used in yyour sitting room with no extra fan noise . Only problem I have is when I tried to slot a Quad Core 1333 Ghz proc into the 755 , the Fan noise goes crazy. This is because the heatsink is a passive one and has no fan. So the internal fans have to make sure the proc is kept cool. I am asking Dell if they have a active heatsink for me. I will feed back to the forum ...

thanx

I have a Optiplex 755 SFF and trying to get the GMA 3100 and the Audio working on it. Have you guys had any luck with these drivers? If so can you post some links plz? Thanks alot.

Just installed Kalyway 10.5.2 on brand new Optiplex 755 (the big one, not the small form factor)
Installation went fine, no problem at all.
Didn't change anything in BIOS.

Here are some specs:
SYSTEM: Dell OptiPlex 755
BIOS: Dell Inc. A10, 04/30/2008
CPU: Intel Core 2 Duo 2.88Ghz E8300
RAM: 4GB DDR2 800Mhz
HDD: Western Digital 80.0GB Raptor WD800ADFS-75SLR2 10,000RPM
VGA: Intel Graphics Controller VESA 3.7. (only 1024x768 is available)
SOUND: ADI 198x Integratred HD Audio - Not Working
LAN: BroadCom 5721C NeXTreme Gigbit Ethernet - Not working
OS: Kalyway 10.5.2

Have few problems, but hope to fix them somehow:)

1. CPU doesn't start if the Kalyway Installation Disk is not in the DVD-Writer.
2. No way to reboot or shut CPU down. Only manually with power button.
3. NIC doesn't work. Ordered this card. Hope it'll work.
4. Would like to hear any suggestions for sound card and video card.
5. External USB HD/Flash drives work fine, but it takes about 5-8 minutes to mount them on the desktop.

Thank you in advance for any help or suggestions.

Hi all,

I spent the last 4 days getting OSX running on the Dell Optiplex 755, with full dual screen DVI capability, USB audio, and network all working on 10.5.5. Didn't have to buy any extra cards or bits. Here's how I did it.

First off, all of this was based on the hard work of others here on the forums, and my friends. I really didn't try or do anything new, just kept trying and trying until something worked.

Second off, I make no claims, warranties, guarantees, or any kind of promises that this will work for you. It just documents the steps and resources I discovered on my way to OSX86 goodness. Do so at your own risk.

My System
System:Dell Optiplex 755, Intel Core2 Duo 3GHZ, 4GB RAM
Hard Drives:70GB Primary drive, 500GB Secondary
Video card: ATI HD Radeon 2400XT 256MB
Network card: Onboard Intel 82556DM.

Installation
I went with iATKOS installation of 10.5.4 to begin with, as that is what I had in hand. Adjust these instructions for your preferred distro:

1. Insert the DVD and reboot.
2. At the welcome screen, choose Utilities | Disk Utility from the menu to create a partition:
   1. Select the root of the boot disk (ie : 149.0 GBWDC WDC1600ADFD)
   2. Click the Partition tab and delete the existing partitions.
   3. Create new partitions (recommend a Mac Extended, Journaled file system)
   4. Under Options choose a GUID partitioning scheme.
   5. Click the Partition button and when it's done, quit Disk Utility.
3. Continue the Installer until you reach the package selections screen. Keep the defaults and add the following:
   1. Stock > ACPI
   2. Disk Drivers > SATA
4. Click Install BUT when the disk validation process begins, click to skip.
5. Once installation is complete, restart, ejecting the DVD so the system starts from disk.

First boot:

1. During the first boot, configure the keyboard, etc.
2. Don't enter anything on the "Enter Your Apple ID" page.
3. On the "Registration Information" page, just hit command-Q, and select "skip".
4. Create the standard local admin account for OS X machines, username "admin", standard password.

System config:

1. In "Keyboard and Mouse" settings
   1. Switch the Option and Command modifier keys
   2. Select "All controls" for tabbing in forms at bottom of "Keyboard Shortcuts"
2. In "Energy Saver" put the computer to sleep when it is inactive for "Never"

Network Configuration

The drivers for the onboard Intel 82556DM can be found at: http://techresearchinfo.blogspot.com/

I originally found them through this post: http://forum.insanelymac.com/index.php?showtopic=128931

Unzip the driver kext file and use Kexthelper to install it. Kexthelper can be found here: http://www.cheetha.net/Kext_Helper/Software.html

Simple steps to follow:

1. Unzip the file.
2. Launch Kexthelper.
3. Drag the file on to the applicaiton.
4. Enter your password, and click Easy Install.
5. On success, restart your machine.

Upgrading to 10.5.5

So first off, DO NOT USE SOFTWARE UPGRADE. Instead, follow the Netkas method for upgrading outlined here: http://netkas.org/?p=50

Here it is in summary:

1. Download the Mac OS X 10.5.5 stand-alone upgrade here.
2. Before running the upgrade, open Terminal and enter the following while sleep 1 ; do rm -rf /System/Library/Extensions/AppleIntelCPUPowerManagement.kext ; done
3. LEAVE THE TERMINAL WINDOW OPEN WHILE THE SCRIPT RUNS AND RUN THE UPGRADE!
4. Once the upgrade is complete, DO NOT HIT RESTART! Return to the Terminal window and interrupt the script (Ctrl-c)
5. Open /System/InstallAtStartup/scripts/1 in your favorite text editor:
   1. Search for the string "/System/Library/Extensions/Dont Steal Mac OS X.kext"
   2. If it exists, replace it with "/System/Library/Extensions/dsmos.kext"
6. Now restart.

The system will actually reboot twice, with it successfully entering Mac OS X the second time.


Side note: I noticed my network connectivity was extremely slow following the upgrade. I re-installed the network drivers and BAM! Was back to full speed.

Following this, USB Audio was working right out of the box.

Video card configuration

The many struggles of getting an ATI HD Radeon 2400XT up and running are well documented on this site. Luckily, just this week a solution was offered by this excellent post:

http://forum.insanelymac.com/index.php?sho...mp;#entry972898

In summary:

1. Download the drivers installer and the app EFIStudio from http://nvinstaller.com
2. Run the driver installer but DO NOT choose EFIStudio with the same installer (it will fail). Reboot.
3. Run the EFIStudio app that was downloaded seperately.
4. Press "Device Path" icon, write "display" into the first textbox and press "Get Path" button, press "To Clipboard" button, close window.
5. Next to Device: select "Display" and the graphic card ("ATI Radeon HD 2400 ..."), and press "Add Device" to open the device configuration.
   1. Replace /plist/dict/key node value (default value is PciRoot(0x0.......) with the one you have in the clipboard (just select old value and paste it over).
   2. Replace every "Iago" string occurrence (you could find other kind of framebuffers like "Lamna") with "Megalodon" string. This includes every substring occurence of it!
   3. Press "write to com.apple.boot.plist" button to insert the EFI string in the system.
6. Add the video device to the ATI driver. In Terminal:
   1. Navigate to the driver package: cd /Systems/Library/Extensions/ATIRadeonX2000.kext/Contents/
   2. Open Info.plist in your favorite editor, with proper authority: sudo nano Info.plist
   3. Add the device id to the <string> element under the <key> for IOPCIMatch. The device id is the product id and the vendor id, which can be found using System Profiler.
7. Still in terminal, rebuild the driver cache: sudo kextcache -k /System/Library/Extensions
8. Then use Disk Utility to fix permissions on the drive.
9. Reboot.

And that was that! All was left was setting up my personal preferences and preferred software installs.

Hope that helps you.

Cheers

Running 10.5.5 on an OptiPlex 755 with a Core 2 Quad Q9550...

Using iDeneb 1.3 10.5.5 DVD, I installed without issue and didn't need to select any additional components. Just have to make sure "SATA Operation Mode" in BIOS is set to AHCI. Also, BIOS A11 seems to support Mac OS X better than previous versions.

Used 82566MM kext from http://techresearchinfo.blogspot.com/ for the onboard 82566DM2.

Audio is not working yet, but http://forum.insanelymac.com/index.php?showtopic=64754 mentions our chip -- the ADI 1984 -- so that may work.

Vanilla 9.5.0 kernel runs fine and have been able to install official updates.
