I am grateful to find that their are people who still lover their MacPro 1,1.
For the last 6 years my MacPro sat in a box with me not knowing how to bring it back. I missed it terribly.
I did not want the new ones as it lack the luster and what I know is capable from the original design.
I did hackintosh to keep running my favorite programs, but its not the same and the performance lacking unless i kept upgrading things. I missed my dual core the most. Then I came across a video that said I can make it run El Capitan. Hope in my eyes to get my machine back. I am still lusting for a MacPro 5,1 -- and hope one day to get one..... but right now my focus is to resurrect my MacPro 1,1.
I have read this entire post from beginning to end.
I followed the instruction on post #1390 The Pikify app
Using my mac mini which when I got it had El Capitan and I have now discovered it has High Sierra. Not sure when that happened.
On the Mini: I re-downloaded El Capitan
External Drive: prepped drive for MacPro 1,1
My plan was to get it running on the external drive, dismount it and place it in the MacPro 1,1
On the Mini: I followed the steps of Pikify -- it completed; each time to reboot -- it failed.
The files are their as I can view them.
I have discovered that Sierra is preventing it due to the changes made.
I have tired to boot into my clone of MacMini with ElCapitan and to other clone drives from previous to have them show up as external but not bootable. When I attempt to boot them using Option Key -- only the MacMini original drive shows.
I tried changing the start up disk and same still happens.
I figured that the drive I created should still reboot in Mac Pro 1,1
but each time I use the Option Key -- the only two drives that show is Lion & Recovery but no El Capitan.
I did make a flash drive, El Capitan but I know that the Mac Pro 1,1 cant see it and its being ignored now by MacMini.
I am frustrated and do not know what more to try.
I feel as thou I am missing something simple......
Any help is greatly appreciated.
Hello SoulCreation,
Welcome.
I have not tried Pikify with that combination. However, you should be okay to “build” the modified installer from your Mac Mini onto the external drive.
El Capitan, Sierra, and High Sierra all implement SIP (system integrity protection). This means that your Mac Mini cannot set the “next boot” volume programmatically because it is running High Sierra with SIP enabled. Correctly signed helper applications might be able to do this, but the Pikify app is not signed for various reasons.
Please understand that the whole Pike-modified system is designed to boot the Mac Pro. It is probable that the modifications are not compatible with your Mac Mini. Therefore it may not boot the Mac Mini.
My recommendation is to re-fit the drive into your MacPro.
At boot, when you hear the chime, hold down the Alt key.
You should be presented with the boot selector screen.
You should see your hard disk.
Select this to boot.
Cross your fingers, hold your breath...
Hopefully it will boot into the installer...
Alternatively, you can keep the HDD attached to your MacMini, run the “Install OS X El Capitan” app directly on the Mac Mini (no need for Pikify, or any other modifications at this stage). I think it will launch (it might not launch or it might not allow you to continue because your Mac Mini is at a higher release of the OS, but if it does, then...) then simply choose to install on the external HDD.
You must then replace the two boot.efi files on the external drive manually.
Optionally, replace the boot.efi file on the Recovery HD partition of the external HDD too (you will need to search for instructions of how to mount the Recovery HD partition).
Once you have done that, re-fit the external HDD to your MacPro.
