I rebooted the Mac Pro (pressing the option key) and selecting to boot from the External USB (the modified installation) – and then after booting from the USB, I cloned the External USB using SuperDuper to the built-in drive on the Mac Pro.Īfter performing the clone, the Mac Pro should boot from the default hard drive. The board-id is different for every machine – the following command will extract it for your hardware:ĥ. I used XCode to edit the XML file (it has a nice GUI) – but you can basically use anything which will edit XML. After extraction the boot.efi file size was 461312 bytes.Ĥ. You are correct – the user Brendan has the correct link – I used the boot.efi from the downloaded boot.zip. Glad that you found the article useful ?Ģ. My next step is to investigate upgrading the RAM on the Mac Pro to extend it’s life even more. My Mac Pro is now up to date and I am a very happy customer ? I then used SuperDuper to clone the external drive (the one with the bootable and modified Mavericks install) to the Mac Pro internal drive and rebooted. I tried booting from the external drive again and it worked!!! I then edited the ist file by adding my board-id and my model identifier (MacPro2,1) to the file in the following location: I then copied the boot.efi (the modified version) from here to the external drive. I looked at the boot.efi file and the ist file and these did not contain the necessary changes.
I wanted to keep my existing install on the MacBook Pro intact).Īfter this I tried to boot the Mac Pro with the external drive which now has a clean Mavericks installation.
Boot with the installable USB on my MacBook Pro (the machine which is supported by Mavericks).
Unfortunately it did not work straight away – My Mac Pro did not boot up. The steps I followed was to build an installable USB using the process described at the Sixty Four On Thirty Two (SFOTT) website. I was still running Snow Leopard (Mac OS X 10.6.8) and it booted up perfectly. I ordered one and swopped it with the old card. I read that the graphics card needs to be upgraded as well and the Apple version of the ATI Radeon HD 5770 was a good choice.
Since support for the MacPro2,1 and earlier models have been dropped in recent releases of Mac OS X, it is not so straight forward to install Mavericks on older hardware. I managed to install Mavericks (Mac OS X 10.9.3) on my MacPro2,1. For those of you with an older Mac Pro – model MacPro1,1 or MacPro2,1…
