Upgrading your Macbook is a very easy task if you are already running a previous version of Mac OS X.

Step One: Download macOS Installer files

You can download the Mac OS Installer file from App Store. Or, if you don’t find the required OS on the App Store, then you can download the Mac OS Installer files from ISORIVER.

Step Two: Formatting Your USB Flash Drive

You can create a boot installer for macOS on Mac. If you are using a flash drive that already has data, be sure to back up all important files as you are about to erase everything in an instant.

Open search engine. Go to Applications > Utilities and open Disk Utility. You should see your flash drive in the External section of the left panel. After selecting it, click on the “Erase” button at the top.

Choose a descriptive name (which you will use later) and be sure to select Mac OS Extended (Journaled) for this format. Finally, click on Erase and you will be done with this step.

The following message shows one of the advantages of DiskMaker X, as it is possible to create multiple installation disks. This means that you can create multiple partitions on the USB drive and have different macOS installers for each partition.

If you prefer to create an installation disk, select “Erase all disk“. Finally, confirm that you want to delete the entire contents of the USB drive.

DiskMaker will continue to create the disk in the background and update it while it works. After a few minutes, DiskMaker X will inform you that your startup disk is ready and will give you some instructions on how to use it.

Step Four: Booting Your Mac From a USB Drive

Simply connect the USB drive you created to an open USB port on your Mac. Turn on the system or restart it if it is already on. Immediately press and hold the Option (Alt) key on the keyboard when it starts.

So we received a couple of Mac Pro 1,1′s which were having issues and decided to see what we could make from them. The idea being to make a powerful, modern Mac as cheaply as possible. The Mac Pro 1,1 is a great place to start – it has masses of internal expansion, and can be grabbed cheaply second hand sources, often for less than £ 100.

The basic issue with the Mac Pro 1,1 is that as factory setup and running it will not run above Mac OS 10.7.5 – this limits it’s usability; especially with Applications like Adobe CC or even modern apps like Photos or iTunes. It also limits some upgrade options; especially with Graphics cards like our R9 – as these earlier OSes do not have the drivers needed.

To start with much of this work has been done by others; I will try and link back to sources as much as possible. That said many people have done similar things in different ways – so I will try and justify my methodology as well (or at least explain the logic behind the decision).

The short short version:

1) Upgrade the firmware to Mac Pro 2,1 (add support for newer CPUs)

2) Upgrade the CPUs to 2 x Quad Core 3.0Ghz Xeons.

3) Upgrade the RAM to above 16GB (we went to 32GB but anything above 16GB should be fine)

4) Install 4 x HDDs (defiantly Matched in size – preferably matched in brand, model etc) – Setup as a RAID 0 – and Test.

5) Upgrade the Graphics Card (we used our R9) – you need to have at least 512 MB VRAM.

6) Install Mac OS X 10.11.6 onto the RAID and modify the boot.efi and <supported platforms> list

7) Boot and enjoy!!

So these steps in detail – with reasons and processes.

1) Upgrade the firmware to Mac Pro 2,1 (add support for newer CPUs)

There is a useful forum here: which has a utility to do this. I followed the instructions and rebooted with the long tone and off you trot! This is needed to add support for the newer CPUs we had in store.

2) Upgrade the CPUs to 2 x Quad Core 3.0Ghz Xeons.

We had these in store from a failed Mac Pro 2,1 which had logic issues – but they can be purchased from eBay very cheaply – there is a great list here on MacRumors which can help you decide which suit your budget / needs. If you want to run lots at any one time then going from Dual Core to Quad Core can be helpful (I wanted to get virtualization working to support legacy OSes at the same time) – otherwise going for higher clock speed is more helpful for processes such as video encoding.

3) Upgrade the RAM to above 16GB (we went to 32GB but anything above 16GB should be fine)

Mac Pro 1.1 El Capitan Installer

If you trust the second hand market; you can pick up some real bargains for 667mhz RAM for these Machines (we do see some customers with issues from second hand RAM but would image it is a small number given how much it appears on eBay etc) – we do sell new modules here.

You MUST have above 12 GB RAM to run El Capitan without it falling over at random intervals – when we had it up and running with 8GB (waiting for a stock delivery) it would fall over every 10 mins or so at random times – since the upgrade it is up for days without any bother.

4) Install 4 x HDDs (defiantly Matched in size – preferably matched in brand, model etc) – Setup as a RAID 0 – and Test.

I had 4 x 3TB HDDs from a previous project which were no longer being used – a bit of a miss match of brands (a pair of Seagate 3TB, and a pair of WD Green 3TB drives). Once these were installed in the Mac Pro I used Target Disk mode via Firewire to a Mac Mini and setup as a RAID 0 using SoftRAID. Using target mode meant that we could install the latest SoftRAID drivers and not have issues later with older versions etc.

This RAID gives over 500MB/s read and write speed (as tested with BlackMagic Disk Speed Test) – and you could expect more with newer and matched drives. Not bad for 12TB of storage!

I used RAID 0 as this Mac will be backed up to a Time Machine server and also be acting as a Media Backup – so failure accounted for.

5) Upgrade the Graphics Card (I used our R9) – you need to have at least 512 MB VRAM.

Video Cards with less than 512 MB VRAM cause issues on these early Mac Pros with the later OSes. I replaced the stock GT with a flashed R9 270x 2GB VRAM. Other cards will work; however the 270x is within the Max power draw spec, has nice out of the box driver support in 10.11.6 and full Dual-link DVI.

6) Install Mac OS X 10.11.6 onto the RAID and modify the boot.efi and <supported platforms> list

I used the Mac Pro in Target disk mode attached to a 2012 Mac Mini running 10.9 – this allowed me to install 10.11.3, create an account and complete all the usual upgrades to 10.11.6 so that I knew it was a fully working install. – Effectively using the Mac Pro as a big hard drive enclosure!

Once it was all working I booted back into the Mac Mini and followed the instructions here:

This involved replacing the boot.efi and adding a line item to the <supported devices> plist. (I went for grey as I am a traditionalist!).

A tentative reboot with the “Alt” key and the 10.11.6 RAID appeared – selected and then the login appeared! It lives! Make sure that the hard drive is selected in the startup disk panel to avoid a long delay on boot and it has been up and running ever since!

How To Update To El Capitan

So now I have a Mac Pro, running El Capitan 10.11.6 with 32GB RAM, 12TB hard drive operating at similar speeds to a modern SSD, the wonderful R9 270X with 2GB VRAM and two displays. Daily it runs four web browsers with approx 10 tabs in each, Parallels with various older OSes from 10.6.8 server upwards, Photos, eMail, Facetime (with a USB webcam), iTunes, iWork and all the usual office tasks and all for less than the cost of a iPad!
