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.

Power PC Macs running any version of the Mac OS prior to 10.4.2 cannot mount GPT volumes. 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. Only Macintel models can boot from GPT hard drives. Intel-based Macs use a partitioning scheme known as GPT. 1 TB drives start at $60 these days (August 2014), and for a serious speed boost – like starting up twice as fast – Other World Computing offers a 44 GB solid state drive (SSD) for just $50 plus $15 for a mounting kit, although you’ll probably want more more capacity than that.įinally, you can upgrade to a faster, more powerful Socket 771 CPU, but that goes way beyond the scope of this page. 2 hard drive seemed like a lot in 2006, but newer drives will often provide much snappier performance due to larger data buffers. For low-end users this should be plenty, but power users can go as high as 32 GB.Ī 250 GB SATA Rev.
As of August 2014, you can get 2 GB from Other World Computing for $58 or 4 GB for $85. You will get okay performance from OS X 10.4 Tiger or 10.5 Leopard with 1 GB, but 2 GB is better – and RAM must be upgraded in matched pairs. If your 2006 Mac Pro has just 1 GB of system memory, upgrade immediately. If you have Office v.X, Office 2004, AppleWorks, etc., it may make good economic sense to stick with Snow Leopard rather and have to replace Office or whatever. If you are running any PowerPC-only software, think long and hard before going beyond OS X 10.6 Snow Leopard, the last version of OS X to include Rosetta support for PowerPC apps. If you want to go beyond OS X 10.7 Lion, the first thing you should do is apply the EFI update mentioned directly above. Be sure you only use a UPS with sine wave output to avoid reducing the life of your Mac Pro. The AC power coming into your home or office is a sine wave, but some UPSes generate a square wave when you are operating from battery power. See Install 64 GB of RAM in Your Mac Pro 1,1 or 2,1. Earlier versions will only boot with 32 GB of less.

However, the 2006 Mac Pro will only boot with Mac OS X 10.8 Mountain Lion or newer. It is possible to install 64 GB of memory after installing the firmware update.

Oh, and did we mention this was the first 64-bit Intel Mac? Unfortunately, it has a 32-bit EFI – but Modernizing the 20 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.
WARNING: If you have updated boot.efi on a MacPro1,1 or MacPro2,1 so you can run Mac OS X 10.11 El Capitan, DO NOT INSTALL SECURITY UPDATE 2018-001 or later. 160, 250, or 500 GB in drive bay one, and optionally 500 GB in bays 2-4. As little as 1 GB of RAM or as much as 16 GB. The buyer can choose from two dual-core Intel Xeon Woodcrest at 2.0, 2.66, or 3.0 GHz. Apple introduced the Mac Pro as a fully customizable quad-core computer.
