Hey! I've just got my Mac Pro 1,1 the other day, and I've spent probably 20 hours total by now trying to install El Capitan and other versions. I finally found a way to do it quickly (did it twice now because I perhaps accidentally tried to update to 10.11.6.. oops).
Here's my guide on how I quickly go from scratch (formatted HDD) to El Capitan on a Mac Pro 1,1.
What you need:
1) OS X 10.7 Lion
2) OS X 10.11 El Capitan
3) USB drive with min. 8GB
Step 1) Once you have your Lion .dmg file ready, go ahead and look at this link: http://www.insanelymac.com/forum/to...for-beginners-updated-for-yosemite/?p=1835023 - Bear in mind, you only need to follow step 2 and 3, but step 3 only up till step 7. Look at the images -> backup image 1 and backup image 2
Step 2) Once you have formatted your drive as GUID, hit "Restore", and applied the installation, it's time to boot up the drive on your Mac Pro.
Step 3) Insert the USB while holding down <OPTION>. Select your newly made USB drive and wait for it to load.
Step 4) Once done, go through the installation and install it on your Mac Pro's newly formatted HDD (do that through Disk Utility if you haven't already).
Step 5) At this point, you should be in the OS ready to open Safari and proceed. Copy over the Install OS X El Capitan.app and place it in /Applications/.
Step 6) Go here and download v14 (it's at the bottom of his post): https://forums.macrumors.com/thread...os-x-el-capitan.1890435/page-56#post-22335903 - You want to extract this zip file, but it should be done already.
Step 7) Open up Disk Utility and click on your HDD which has your Lion installation on it. Hit Partitions at the top and create a new partition. Call it something like "Capitan". You should now have 2 partitions.
Step 8) Open up Terminal and go to your folder using the command cd. Something like this, if you just downloaded and extracted it: cd ~/Downloads/pikify3.1
Step 9) Type in this command (assuming your new partition/volume is called Capitan):
sudo ./createpikeinstallmedia /Volumes/Capitan/
Step 10) Follow what the screen says and restart immediately when it asks (no rush, just don't waste your time! haha)
Step 11) Follow the screen instructions and install your new El Capitan on your Capitan partition. Once done, it should reboot and so on, and you should be on El Capitan 10.11.1!
After spending many, many hours trying to install this on my Mac Pro 1,1, I finally found a good way to do it, which actually doesn't take that long. I can do all this within an hour, and that includes about 20 minutes of transfer for both installations (each).
Hopefully this can help someone else, as I'm getting tired of watching old tutorials which turned out never worked.
You may ask: Hey Morten, why do you post old tutorials? Well, they worked for me and I bet they work for others as well. I only needed two links to really get going, which were these:
1) http://www.insanelymac.com/forum/to...for-beginners-updated-for-yosemite/?p=1835023
2) https://forums.macrumors.com/thread...os-x-el-capitan.1890435/page-56#post-22335903
PS: Oh, and if someone knows how to upgrade safely to 10.11.6 from this guide, please let me know. I'm curious to see if this fixes my 8MB VRAM bug with my Nvidia 7300 GT.
