Mac Pro (Mid 2006)


Apple introduced the Mac Pro as a fully customizable quad-core computer. The buyer can choose from two dual-core Intel Xeon (“Woodcrest”) at 2.0, 2.66, or 3.0 GHz. As little as 1 GB of RAM or as much as 16 GB. 160, 250, or 500 GB in drive bay one, and optionally 500 GB in bays 2-4.

For graphics, Nvidia GeForce 7300 GT is the default, and you can add one, two, or three more. Or choose an ATI Radeon X1900 XT or Nvidia’s top-end Quadro FX 4500.

If one SuperDrive isn’t enough, put in a second one for US$100 more. And you can upgrade from Apple’s regular wired keyboard and Mighty Mouse to the wireless (Bluetooth) version.

  • The two things unexpectedly not included by default are Bluetooth 2.0 and AirPort Extreme, which are standard on all other Intel Macs.

A headphone jack, two USB 2.0 ports, a FireWire 400 port, and a FireWire 800 port are located on the front of the Mac Pro for easy access.

Oh, and did we mention this was the first 64-bit Intel Mac? Unfortunately, it also had a 32-bit EFI – but Modernizing the 2006 and 2007 Mac Pro to Go Beyond OS X Lion by Robert Bryant explains how to change the boot.efi file so it can run OS X 10.8 Mountain Lion and later.

Intel-based Macs use a partitioning scheme known as GPT. Only Macintel models can boot from GPT hard drives. Both PowerPC and Intel Macs can boot from APM (Apple’s old partitioning scheme) hard drives, which is the format you must use to create a universal boot drive in Leopard. Power PC Macs running any version of the Mac OS prior to 10.4.2 cannot mount GPT volumes. PowerPC Macs won’t let you install OS X to a USB drive or choose it as your startup volume, although there is a work around for that.
