This means, i can rund the Installation on my rMBP on a extern HD and can switch this HD after the installation into the Mac Pro 1,1.
This is exactly what i try over days. I give it another try this evening...
Just a thought, but I would reset the PRAM and SMC just for the sake of doing it. I first
loaded 10.11(1-3) on an old drive to do the testing and by the time I did the final install
I had found that doing the PRAM reset did a lot for a smooth install. You might have to doo an OPtion boot to select the correct boot drive, but that is a lot easier than banging my head against the wall.
I've just completed this. Fresh download of El Capitan from Mac Store, ran the v8 boot loader and installed directly on my Mac Pro. All done! However, I see what you mean about the old graphic card support. I knew I needed a new card but waiting for pay day.
Anyone else having issues with their optical drive?
When I insert a disc it doesn't show up in the finder. I have had this problem since I first went from Lion to Yosemite. Figured it just came with running an unsupported OS, wondering if that is actually true

No, not for me. I still have the original Sony/Apple DVD/CD rewriter (A.K.A. SuperDrive) in bay 1 and a TSSTcorp Bluray drive in bay 2. Both work fine. The original DVD drive is still connected on the parallel ATA bus, whilst the Bluray drive is connected to one of the motherboard SATA interfaces.
It's more likely to be either bad media, or that your drive is perhaps reaching the end of its life. Reliability has improved with each generation, but these things are still susceptible to failure. The laser diodes in particular are known to deteriorate over a long period of usage.
If you have a compressed air canister, it might be worth attempting a clean before deciding to buy a replacement.
Also check the system.log file (using the Console app). Insert a problematic disk and see if you get any disk related log messages...
A final thought occurred to me... You say that you have been upgrading, so you may have some old extensions that might be interfering (it all depends on how you did your upgrades). Have you tried a reboot into safe mode? (Safe mode only loads Apple-supplied extensions I believe). Also, if you try a safe mode boot, be patient because I also think it triggers an disk check (fsck) which will take some time to complete depending on the size(s) of your disk(s).... I think you can still get to safe mode by holding down the shift key immediately after the startup chime....

PRAM and SMC reset I've already done. But I give it a try again this evening. Yesterday I have not enough time for testing and installing.
Remember, we are forcing hardware/software/firmware to do things that they were never meant to do.
I know. But i had already a running El Capitan System on this Mac Pro, which I had constantly updated from Mavericks over Yosemite up to El Capitan with only chanting the boot.efi on a compatible System.
But I need the HD's for my new NAS and I thought, that I wouldn't be such a great thing to make a new clean working El Capitan drive for my mac pro again. So I'am a bit confused about the Problems which I have now setting up the System again.
Time to rebuild all of those emergency USB installer sticks, and replace that copy of the Install OSX El Capitan.app that you have backed up somewhere, because if it is dated before February 14, 2016, it will no longer work.

The text in your screenshot seems to point towards a problem with a firewire device. Disconnect all your peripherals except mouse, kb, monitor. Especially disconnect the firewire devices....
If you built the installer on an external firewire disk. Use Disk Utility and run first aid on the whole disk as well as any and all partitions. Consider a complete reformat of the firewire disk (that you put the installer on)...
Thanks for the suggestions, I will disconnect the firewire device (it's an audio device). I put the installer on a USB drive but looks like I need to rebuild it anyway with a newer version of the installer.
I installed via a Macbook Pro that supports El Craptain by default. Random kernel panic, RAM CRASHES EVERY 30min. 6GB of ram, Curcial and Hynix.
If I was at work all the time I spent tinkering with my old Mac Pro 1,1 - I could have bought a brand new Mac Pro! Just a heads up!

Do you have any 512MB DIMMS in your setup?
A number of users have reported numerous crashes and difficulties. Empirically it has been discovered that the combination of El Capitan, 32-bit-efi machines, and 512MB original DIMMs seems to be the common factor. Every user who has reported kernel panics has been advised to buy new larger capacity RAM DIMMs, and has subsequently reported back that their system has stabilised. The recommendation is to purchase 2GB or 4GB DIMMs in pairs, as many as you can afford. (Remove the 512MB DIMMS entirely).
Personally, I have 8 x 4GB DIMMs, some of which have Apple-style heat sinks, and some of which have the more typical flat heat spreaders. My MacPro 2,1(1,1) was rock solid at Yosemite, and has been rock solid under El Capitan.
I just installed El Cap following your recipe, and I did manage to install El Cap, but the automatic ‘Boot 64’ was not installed as described.
Further, the script commands after ### DONE PIKIFYING ### failed.
[doublepost=1457366497][/doublepost]Since I installed El Capitan I’ve run into the issue that if I put my Mac Pro to sleep at night, then it will wake up during the night and ramp up the fans to maximum.
I’ve have reset the SMC and PRAM successfully, but to no avail.
One other user told me the commands after "Done Pikifying" have caused problems.
Don't worry about them, I added them to try and detect if the Mac is a 1,1 or a 1,2 MacPro AND has the suggested 12GB or more of RAM. If the RAM is low it just prints a warning. There's no other impact. If it is throwing any errors or warnings they can be safely ignored.
If you saved the error messages, or can remember them, please post them. I'll see if I can figure out what is causing the issues.
It obviously works okay on my MacPro 1,1 (2,1) without issue. There must be some differences between your machine(s) and mine. What version of Mac OS X were you using when you built the installer? It is most probably a version issue....
The fans do that some times. It's Mac OS X, but remember (before asking Apple about it) we are running a version of Mac OS X on unexpected hardware from Apple's perspective.... Take a look at your System Preferences > Energy settings, and maybe your sharing settings. MacOSX will periodically wake just long enough to announce its presence to the network, then go back to sleep. I can't remember which settings affect the behaviour, there are probably a few....
Hi i am new to os x and i have got a macbook 2,1model number A1181 and was wondering if you can help me get either el capitan or poss yosemite 10.10.5 on it plz i have gone through loads of forums and videos on youtube but everything i seem to do dont work and the os x thats on it is rubish to the 1 im running virtualy on my windows laptop
I ran the script on Yosemite (last version). Regrettably I don’t have the log anymore.
I have upgrated my MacPro 2,1 from Snow to El Capitan. It works well. But, one more thing... Terminal freezes. Any idea?
No way. This machine will not support anything past 10.8, no matter how you hack it. Getting 10.7 on it is relatively simple, 10.8 is a major surgery and any later system is just impossible.
Thanks for your Help i get my Mac Pro 1,1 running El Capitan 10.11.3 at least by Setting it up via my rMBP and chanching the boot.efi by Hand.
But at least I have System crashes many Times, so it's no fun working with it. Before my changes with the HD's and the decision to set up the System again from the ground I had 10.11.1 running on the Mac Pro 1,1 and I had no System crashes at all. So I think it could be the 10.11.3 my Mac pro can't handle.
So I want set up the System again with the 10.11.1, but I can't find it anywhere to download. Does anyone here knew a Downloadlink that's working for the 10.11.1?
