Hey guys. I'm attempting to install OSX onto my Dell Optiplex 745 as well. The only difference in specs is that it is equipped with a Geforce GT 240 as the video card.

 

The issue I'm having does not seem to be apparent anywhere else. Basically, when I attempt to boot the installer USB, I can get into the bootloader just fine, but it takes a long time (about a minute or so) just to get into the bootloader.

 

Once inside the bootloader, I try to load the installer, and the screen goes black. It doesn't start loading the system at all. It's not a graphics issue, because even without graphics support, you can see the verbose boot before the screen goes black. In this instance, I can tell that it can't get past the bootloader because Ctrl+Alt+Delete causes the system to reboot, which does not happen when it is loading OSX.

 

For reference, I did go into BIOS and set Hard drive to Legacy, turned on usb booting.

 

To try to get around this problem, I attempted to install OSX to the drive externally using my main system and the installer USB. After doing that, I installed Clover to the hard drive. When I attempted to boot directly off the hard drive, it was the exact same situation. Clover took a really long time to load, and when I attempt to boot into OSX, the screen goes black and does not load the system at all.

 

I am doing this to install Yosemite, so I'll be cross-posting on the Yosemite forum, and Latitude forums but this is also valid for previous versions as well because I've noted this problem in the past when I tried loading the Mountain Lion installer using Chameleon.

This machine dell optiplex 755 could run yosemite also, use the same method for dell xps410. Run with chamemeleon boot loader.
The guide is here. http://www.insanelym...-show-4-drives/
You need fakesmc, nullcpu, appleintelpiixata, patch applerRTC, appleLPC for show 4 drives.
Good luck to all.

hi thanks to the 755 kexts in this thread i got 10.9.0 running on an internal hard drive.

I used niresh to install originally to one machine did the boot fix and cloned the drive.

without the 755 kexts i could only boot with hdds in  legacy mode.

 

once they were installed the hdd controller was recognised this was yesterday, having left the machine running i found upgrades waiting to be installed dreading it i let them install. Can't boot , oh f...

ok i popped out the drive and put it in a usb cradle and booted in safe mode.

about this mac showed i was now running 10.9.5 mmm not sure about this

used kext wizard to install the 755 kexts see if it would work or back to square 1 and a full reinstall

replaced the drive back on to sata and again tried booting with -x

it worked so tried booting normally it succeeded :)

 

everything seems to be fine.

 

 NVIDIA GeForce GT 610 1024 MB

2.66 GHz Quad-Core Intel Xeon / quadcore 2 9600

8gb ram 

 

So 755 can run 10.9.5 not sure if i'd want to go further thou.

It could run 10.10, with mine cpu is Core 2 Duo, it seem O.K. Excpet the HDMI audio by Nvidia GT610 is I can not make it to work. I am not sure about VoodooHDA.

Attached File  IOPCIFamily.kext.zip   69.89KB   7 downloadsAttached File  Extra.zip   2.69MB   5 downloadsI'm stuck while my original method worked I got into trouble with the hard drive i used and am back to 10.7.5 

I've got a install image that my hack uses to create the boot usb, 

when i boot with it I'm just reaching the gray apple screen for an instant and then the computer reboots

any suggestions ? I've put the recommended kexts in ee and s/l/e the graphics card is an nvidea 610 which works fine in 10.7.5 but isn't recognized before that saying it has 3meg of ram only.  I've upgraded my bios to a19 as people seemed to have success with that the old version was A11

 

Phew done it, and it wasn't that straight forward 

First thing I had to do was remove my graphics card and reinstall the standard Dell one. Without which I got memory hole and system halted.

 

with that card I was able to boot with -x and -v but to install i needed to go in the bios and select legacy mode this enabled me to install to a usb hard drive.

 

With IOPCIFamily.Kext from my ML install I installed the to s/l/e on the usb drive this then allowed me out of legacy mode and back to achi/raid. I then tried to reinstall my graphics card which didn't work back to system halted so I decided to try an extra folder which was designed for yosemite. Installing this extra got my usb drive booting with the gt610 card in place.

 

my ml install was on a drive with three mac partitions i have another drive which boots linux and windows i booted up with that and a linux partition (Mint but it doesnt matter) and ran gparted it could have been done with a livecd or a linux installer on a usb stick as long as the partitions are not in use (mounted) you can work on them.

 

so i deleted the last 2 hfs partitions on the ml drive and created a single one in place.

 

I then rebooted into ml on that sata drive and used disk utility to restore mavericks from the USB hard drive partition to the new partition on the internal sata drive.

 

I then unmounted the usb drive and rebooted to the ml sata drive and selected the mavericks partition after a file system check it came up and I decided to write this post.

Has anyone been able to install Yosemite with clover bootloader? I have the 745 which is almost identical. I cannot get the sata port to be recognised. I have tried everything port injectors switching around the dvdrom and hard drive sata connectors. Updated the bios. Tried legacy and normal settings in bios. I am stupmed.

It's probably the same sata controller as  the 755, chameleon worked for me, i've never got anywhere with clover but that could be just me. Try installing to a usb drive, if that works then you can work on the sata. if the worst comes to the worst you could fit a usb hard drive internally (there are headers and an old cable with a socket on one end and the header on the other would do the job). I think once you have the os installed on that drive you will be able to find a working kext. which kernel version is it I think 12.5 was the version number on Mavericks and ML and the kext I linked is for that version i think.

 

We are pretty lucky to be able to mix and match some kexts from other versions of osx on linux they would need to be compiled for the kernel version.

well i'm very stuck i'm getting to resetting iocatalog and it stays that way 

heres a bad photo of where i get to.

Ok finally got to 10.9.5 and it was a struggle 10.9.1 went on easy and i spent most of the day trying to get 10.9.2 working right and failing.

 

so i used 3 mavericks partitions two on a usb hard drive i got all 3 to 10.9.1 using disk restore. 

I then went to work on one of the usb partitions 10.9.2 and 10.9.3 were able to be installed on one partition while being booted on another. 10.9.4 required me to be booted up on the disk i was installing it on. 

I switched out the graphics card gt610 for the built in dell which let me boot using -v -f PciRoot=1 and -x -s

i was able to boot up 10.9.3 from the usb drive but i lost the internal drives and then installed 10.9.4 and 10.9.5 

I then booted a different partition and used kext wizard to install some kexts into /s/l/e on the usb drive and then repaired permissions. This got my internal drives back and then i switched the gt610 back in and at this point i was using -v -f -s

 

the next stage was to use the other usb partition with 10.9.1 to restore the 10.9.5 partition to the internal drive first boot i used -v -f -s and was ok and next went for it with no flags and it came up without a problem.

 

I've attached the kexts i used (its now an imac early 2009) hope this is usefull.

 

just attached a couple more files which may be useful a dsdt  that seems to help avoid getting the cmos reset and a patched dvd framework that allows playback on an external drive.
