Mac Pro 1,1 running Mavericks from SSD. Has been patched to run this version of the OS, and has run for many months. After working well with OS10.9 for some time, on power on the boot sequence does not begin. The fans run at high speed (fans almost never ran in the past). Monitor is dark. Does not accept keyboard or mouse input. Power button will not work to turn off. Only way to stop fans is to pull the plug. As this will not boot, cannot run diagnostics. Have removed, cleaned & reinstalled RAM cards, but problem remains.

Feb 10, 2020 There’s no doubt that the 2019 Mac Pro is an incredibly powerful machine. However, it looks like Google Chrome can bring any desktop computer to a standstill if we push it hard enough. Popular tech YouTuber Jonathan Morrison, who published some really interesting Mac Pro videos recently, decided to spec-out Apple’s highest-end computer with 1.5TB DDR4 ECC RAM and push it to.
Sep 09, 2015 A quick word about motherboards. I had specific requirements when it came to a motherboard for this build. Unlike my first Apple Mac case mod, a power Mac G5 the Mac Pro has the four hot swap drive bays which I wanted to retain, this meant that I could not cut the double skin top shelf of the Mac Pro to allow a full size ATX motherboard to pass behind as there is not enough space.

Community member Julius Chan has sent us this handy guide to getting a 2006 Mac Pro to run the lastest Mac OS X Yosemite.

Here is his helpful guide.

First of all, all of the below are regarded as hacks. If you end up with bricked Mac Pro, then it’s your own silly fault. None of this stuff is qualified. You’re building what I refer to as a “Frankenmac”.

History

Part of my day job is building Pro Tools rigs for high-end customers. They can afford the best, so I get to tinker with the latest Avid qualified hardware and software available: “iAshtray” Mac Pros, tank-like rack mounted Sonnet chassis, HDX or HD Native cards etc. All fully qualified, just the way I like it.

This is all jolly nice for my clients, but my own personal 2006 Mac Pro 1,1 with a Cinema display (purchased from a friend for a pittance) sits there languishing quite a few operating systems behind on OSX Lion 10.7.5 running Pro Tools 10.3.10 HD. Bugger…

I’d read that some very clever folk had managed to persuade an old Mac Pro to run Mountain Lion and then Mavericks, and searching the Interwebs, I did indeed find a number of solutions that seemed to require entering a lot of commands in Terminal, creating boot partitions and generally patting your head and chewing gum at the same time. So I decided to wait a wee while until I found a more elegant solution. The wait seems to have been worth it, as I now have my poor old machine running on OSX Yosemite 10.10.2 and Pro Tools 11.3.1

The main restriction for a 2006/7 Mac Pro is that it was designed to boot into a 32-bit environment, even though a lot of the internal hardware was 64-bit capable. The clever bunnies out there in the Wild World Webby, have managed to fool a Ye Olde Mac Pro to run in 64 bit EFI.

Things that you will need:

A Mac Pro 1,1 or 2,1 Cheese grater desktop with OSX Lion 10.7.5 system drive
8GB USB drive
A graphics card better than a GT120, I used a Radeon HD 5770, original mac version with its appropriate power cable. There are flashed PC cards out there, but they won’t display a boot screen. I like a boot screen, so I purchased a proper Apple card (2nd hand)
We are sorry but the pre patched version of OSX Yosemite 10.10 is no longer available. It would appear that Apple have asked for it to be taken down.
Either boot.efi file downloadable here. Black is a white Apple on a black background and Grey is the traditional Apple boot screen:
Black: Sorry no longer available
Grey: Sorry no longer available
I chose the black screen as I dual boot into OSX Lion 10.8.5 or Yosemite 10.10.2. The black screen tells me instantly that I’m booting into Yosemite.
A spare hard drive, mechanical or SSD for the new system drive. You could partition your old Lion drive, but I prefer to build on drive that’s minty fresh. If I stuff anything up, I can always boot back to my untouched Lion system drive. Contingency plan…
A download of Yosemite 10.10.1 or 10.10.2 Combo updaters http://support.apple.com/kb/dl1786?locale=en_US
A download of Diskmaker X http://liondiskmaker.com/

All of the above cost me around $200 US, I had a spare 1TB 7200 rpm SATA drive, USB drives are cheap and seem to breed like rabbits. They also seem to disappear down the black hole that guitar picks, iLok 2 lids and single socks end up.

Preparation

I’m going to assume that you’re booting from your old Lion system drive, so go ahead and download all the bits and bobs from the links above. Depending on your internet speed, this may take some time, so make a nice pot of tea. If you’re in Australia, as I am, you have plenty of time to make a nice batch of scones with jam and cream, thanks to our advanced network infrastructure.

Once you’ve finished downloading, place the files somewhere safe, it could be on a USB drive etc

I popped the files on one of my media drives temporarily so I could access them from my old system drive or my new system drive. (yet to be created, mwahhahaha)

Hardware Installation

Open up your Mac Pro, take the nasty GT120 graphics card out and pop in the ATI Radeon 5770. This card takes its power from the motherboard, so make sure you’ve got the correct power cable.

Install your new system drive, but leave the Lion drive in for the moment. I usually put new, unformatted drives in bay 4… Just so I know…

Reboot your rig into OSX Lion and make sure the new graphics card is AOK. You could format your new system drive at this stage as well. Call it something like “Yosemite HD” or “Kevin” if you wish.

Double and triple check that you’re formatting the correct drive… (Doh) Bay 4, remember??

Software Installation

Mac Pro 1.1 Ram

Open up Lion Diskmaker X and follow the instructions to create a bootable USB “special” Yosemite installer from the big Yosemite image you download before. This is the patched version of Yosemite.

Don’t install the Apple App store version as this does not have ze patch…

This can take some time, so be patient and do something useful for the planet, like knitting a vest for our wee penguins on Phillip Island.

Install Yosemite from USB drive to your new “Yosemite HD” system drive. Bay 4, remember?? Hold down the Mac option key to choose your boot drive after start up chime.
Install the boot.efi patch, I used the black version. Restart the mac, hold down the mac option key to choose your boot drive after start up chime You should now be able to boot into either OSX Lion or Yosemite 10.10 flat. Woo Hoo!
