El Capitan Boot Screen Compatible Video Cards For Mac Pro 31

Mac Pro introduced in early 2008 or later Xserve models introduced in early 2009. To find your Mac model, memory, storage space and macOS version, choose About This Mac from the Apple menu. If your Mac isn't compatible with OS X El Capitan, the installer will let you know.

I've unfortunately gotten rid of my trusty Mac Pro 1,1, and therefore this repo will no longer be updated.

Upgrades I have completed on the Apple Mac Pro 1,1 in order to get it El Capitan (OS X 10.11) ready along with code, scripts and links to products and utilities. Magicscan software download for mac.
