So these steps in detail – with reasons and processes.
El capitan for mac pro 1.1 mac os x#
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).ġ) Upgrade the firmware to Mac Pro 2,1 (add support for newer CPUs)Ģ) Upgrade the CPUs to 2 x Quad Core 3.0Ghz Xeons.ģ) Upgrade the RAM to above 16GB (we went to 32GB but anything above 16GB should be fine)Ĥ) Install 4 x HDDs (defiantly Matched in size – preferably matched in brand, model etc) – Setup as a RAID 0 – and Test.ĥ) Upgrade the Graphics Card (we used our R9) – you need to have at least 512 MB VRAM.Ħ) Install Mac OS X 10.11.6 onto the RAID and modify the boot.efi and list To start with much of this work has been done by others I will try and link back to sources as much as possible. It also limits some upgrade options especially with Graphics cards like our R9 – as these earlier OSes do not have the drivers needed. 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. 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 idea being to make a powerful, modern Mac as cheaply as possible. 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.
