Big Mac Pro issue (1,1 - 2006) Three days ago for some damn reason I decided Snow Leopard wasn't good for my Mac Pro 1,1 anymore. I decided to embark on the quest of updating it to El Capitan.

So using the Pikify and downloaded the software it took me 3 days but yesterday I finally managed to boot it up and it was working okish... bit slow and had some issues with Final Cut but it was working.
This morning I decided to run updates and well... shit gets serious...

When I boot it up, I get the  logo and the bar starts filling up it gets to half way and it switches to my second screen and starts again (this time slower) reaches half, all screens go grey and I get the Language selection. Once I select the Language I'm stuck at a Utilities window where I can choose to restore from a backup (which I don't have) choose to reinstall OS X (done that but nothing changed) find help online or start Disk Utility up to try and repair damaged disks (tried that but all disks are working fine)...

I have 3 drives mounted on my computer:


500gb - 6 GB free space (OS installed here)
500gb - 293,51 GB free space
1TB - 217 GB free space (Windows 7 installed here)


12 GB RAM - 2,66 processor - 5070HD ATI

If anyone needs any more info please let me know...

PS: I tried booting in Safe Mode, which doesn't work.
I tried resetting VRAM by pressing cmdaltPR, but nothing changes.

Another big issue is the fact when I try to open Terminal I'm logged in as bash-3.2 not as User.
With a machine that old, I'd probably use a different Mac to download a clean OS installer and then try installing to a totally new drive (USB or FireWire) to ensure you have working hardware that can run an install.

Installs exercise a lot of functionality that only runs at install time. A marginal machine can keep running for a long time past when it can actually pull off an install let alone an install/upgrade in one pass.

The benefit of this is you keep your data safe (assuming you don't have a backup) and don't have to wait hours/days for migration of settings and data to know if the simple OS install worked or not.
