El Capitan – running on a MacPro1,1 9 June 2015

Posted by David Wilson in General.

I posted almost a year ago about my success with Yosemite running on a MacPro1,1 – here is that post. https://dgwilson.wordpress.com/2014/07/20/yosemite-on-a-macpro11/

I’ve now been able to get El Captian running on the same MacPro1,1 and it was easy. Although it did take a couple of hours.

The MacPro already had a Yosemite installation.

As for the original post I connected the MacPro to my MacBook Pro over Firewire 800 with the MacPro running in Firewire target disk mode. Next I ran the El Capitan installer – I had already downloaded this to my MacBook Pro. I set the installation to the Yosemite OS drive. The installation ran for some time… and some more time… – it completed successfully and rebooted as you would expect where I was subsequently presented with a logon screen. It took a while before I got a desktop up… but eventually the MacBook Pro was running El Capitan off the Hard Drive in the MacPro.

Next I changed by startup disk back to the Internal drive in the MacBook Pro and rebooted – except I gave up on that after a while and power cycled the MacBook Pro. When everything was back online and all of the drives were connected again (over firewire) I then had to update the boot.efi… via Terminal

cd /Volumes/El Capitan/System/Library/CoreServices/
chflags nouchg boot.efi
cp boot.efi boot_dgwcopy.efi
cp /Users/dgwilson/Desktop/Hackintosh/boot.efi boot.efi
chflags uchg boot.efi

Quit Terminal
Eject the MacPro drives
Disconnect the Firewire Cable
Power Off MacPro
Power on MacPro – option key held down
Select El Capitan drive
Continue boot

p.s. I installed some software under El Capitan that required a system reboot. The machine did not come back after the reboot – instead booting into Yosemite which was installed on another drive. I’ve since managed to fix the issue… so for the record…

Make sure you’re running the boot.efi (as above) and it is installed in



with the appropriate commands of

chflags nouchg boot.efi

chflags uchg boot.efi

for both directories.



USB Missile Launcher and Satzuma Missile Launcher 1 June 2015

I have received reports that the Satsuma Missile Launcher is working with my USB Missile Launcher software.

You will need version 1.8.2 of the Missile Launcher software, available here:

And you will need to do some configuration to tell the software how to find the launcher and control it.

Thank you to those that have contributed via comments here with the results.
