The Mac Pros can run much later OSes than officially supported, although there are caveats. Installing unsupported OSes can be done easily using scripts or using OpenCore. These scripts have been named after the authors who created them. Pike's Script is exclusively for the 1,1/2,1. DosDude1's scripts cover a brevity of Macs, including the Mac Pro 3,1/4,1/5,1. All but the 1,1/2,1s can run modern iterations of macOS using Dosdude1's hacks, which can be found at his website dosdude1.com. Below is a list of the official vs. unofficial supported OSes. To understand OpenCore, it's important to have a grasp of the history of hacking macOS to run on unsupported hardware. Prior to boot loaders, the vector to run the latest macOS were scripts that generally modified the OS itself so it'd pass hardware checks to install and boot and often included fixes. The most popular and prominent were the DOSDUDE1 installers. While these scripts worked, they were an imperfect solution, as installing updates would break the modifications and ultimately left the updated OS unbootable. Installing updates meant re-running the entire macOS installer. OpenCore came from a desire to create a bootloader to allow for per-boot injections to solve the problems for Hackintoshes or Apple hardware, be it legacy hardware support, drivers, or boot flags. The advantage is that macOS itself (mostly) was not being modified, and changes could easily be swapped by reconfiguring the boot loader. While the process of OpenCore is more complex for the end-user, its advantages are massive, thus drawing in a larger community of both Apple hardware owners and Hackintosh users. Many notable people have contributed to OpenCore, including people like DOSDUDE1. With OpenCore Legacy Patcher, the installation process of OpenCore's friction has been simplified into a point-and-click install. It wasn't always this way, and it took the work of many brilliant people to get to where we are today. OpenCore wasn't without its o...
