Introduction

For the first time since OS X 10.8 Mountain Lion in 2012, macOS 10.12 Sierra has changed the official minimum requirement to run it, leaving some older (but still perfectly capable) Macs behind.

Here's a thread for people to discuss and offer solutions for the newly unsupported Macs in macOS 10.12 Sierra. This post will be updated with solutions as they become available.


Apple History

OS X 10.6 Snow Leopard was the first OS X version with optional support for a 64-bit kernel, allowing booting either with a 32-bit or 64-bit kernel. However, Apple did not support booting the 64-bit kernel in Macs that shipped with EFI32 firmware, even if they had 64-bit processors capable of running the 64-bit kernel. When Apple dropped the 32-bit kernel entirely from OS X, starting with OS X 10.8 Mountain Lion, EFI32 Macs no longer had an Apple-supported mechanism to boot newer OS X versions.
OS X 10.11 El Capitan includes System Intergrity Protection (Rootless security). It makes sure that System file permissions are automatically protected, and updated during Software Updates. The Repair Permissions function is no longer available and access to system files that we need to use in this thread may be locked.
Older Macs that lost support in macOS Sierra have an USB related issue that prevents the built-in USB as well as the thereon connected Input Devices and Bluetooth from working.

Models Tested:



The support for legacy Macs include iMac 5,1; MacBook 2,1 and MacBook 3,1 that could install Mountain Lion, Mavericks, Yosemite with MacPostFactor or OS X Extractor (in the spoiler below) have been dropped in OS X 10.11 El Capitain. Mac Pro 1,1 and 2,1, while able to update to El Capitan with the methods in the spoiler below, are currently not supported by macOS Sierra.
