Unfortunately, this being the world it is, a disclaimer. So to keep this applicable to everyone, I’ll recommend you only have one screen connected. Most people won’t have to do this, but some graphics cards have issues getting to the recovery OS when multiple displays are connected. – If your Mac has multiple displays connected to it, disconnect all but one of them.
zip file downloaded to your system with everything you need to install OpenCore on your Classic Mac Pro.
Pick and download the latest one (0.7.1 at this time of writing) – Martin Lo’s preconfigured OpenCore for the cMP package.įor that package, go to this page, scroll down until you see all the attachments.
– 144.0.0.0.0 Boot ROM (You get this by running the Mojave installer and just doing the firmware update that is a part of it) Most of the text in this guide is simply explaining stuff, so don’t let the fact you see a bunch of text scare you off, this really is a simple process. This guide may have steps in it that are not needed for most people, but I include them so that the guide can work for anyone that reads it. This post is the quick and easy guide that should have anyone up and running with OpenCore on the cMac Pros in minutes. I have no experience (yet) with other versions of OpenCore, such as the Legacy patcher, but I fully intend to explore that as well at some point. If you don’t know what OpenCore is, read about some of its benefits here.
AirPort Extreme (802.11a/b/g/n) and Bluetooth 2.1+EDR is standard.Īlthough the "5,1" models look essentially the same externally as the "4,1" models, all "5,1" models are equipped with faster graphics and there are significant technical differences for higher-end "Westmere" models as well with faster processors and as many as twelve cores (two six core processors) via custom configuration.OpenCore is, for lack of a better word, amazing.
Ports include five USB 2.0 ports, four Firewire "800" ports, dual Gigabit Ethernet, two Mini DisplayPorts and a dual-link DVI port, among others.
It also could be equipped with other dual Six Core processors, but these are documented as their own models for convenience.īy default, this model is configured with 8 GB of 1333 MHz DDR3 ECC SDRAM, a 1 TB (7200 RPM, 32 MB cache) 3Gb/s Serial ATA hard drive, an 18X dual-layer "SuperDrive" and an ATI Radeon HD 5770 graphics card with 1 GB of GDDR5 memory.Įxpansion includes two external 5.25" "optical" bays (one free by default), four internal 3.5" "cable-free, direct attach" hard drive bays (three free by default), and four PCIe 2.0 slots (one free PCIe 2.0 x16 slot and two free PCIe 2.0 x4 slots with the default single graphics card installed). The Mac Pro "Twelve Core" 2.66 (Westmere) is powered by dual 2.66 GHz Six Core 32-nm Xeon X5650 (Westmere) processors with a dedicated 256k of level 2 cache for each core and 12 MB of "fully shared" level 3 cache per processor. However, this system has significant technical differences, and is documented as its own model, accordingly. This model was offered as a custom configuration of the Mac Pro "Eight Core" 2.4 (Westmere).
