- Apple does not support OS X El Capitan on the original 2006/2007 Mac Pro and 2006 Xserve. These 64-bit Mac Pros and Xserves have EFI 32 firmware and can't natively boot OS X El Capitan 'out-of-the-box', but are easily capable of running it with a different boot loader. Once a new boot loader is used to launch the native 64-bit El Capitan kernel.
- The full operating system is a free download for anyone who has purchased Mac OS X Snow Leopard, Lion, or Mountain Lion or has a Mac preloaded with OS X Mavericks, Yosemite, El Capitan, or macOS Sierra. Download the Application from the Mac App Store using your Apple ID on any Mac or functional computer running OS X 10.7.5 or later.

If you have NOT previously installed High Sierra, you can download and install this package (if running OS X 10.10 Yosemite or later) to install the latest BootROM version (you MUST reboot after installing the package to apply the firmware update). When installing, ensure your system is plugged in to power, or the update will not be installed.

Personally, I did it on my Mac Pro ’08 (MacPro3,1), which officially supports only OS X 10.11 „El Capitan“. With the „macOS High Sierra Patcher“ I managed to install the latest macOS (10.13). Now I have Siri and many other new features on this computer. The usage is still very good.
