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.
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.

What will happen when an update comes along? Will it just update without destroying the modified files or will it be necessaryto boot from the installer and

My question is when an updater comes along will it just install OK or will it destroy some of the modified files and then it will be necessary to boot from the installer drive and run the patcher again?

Yeah, more than likely, all you'll need to do is install the update, then run the post-install patch from the Installer drive after the update is installed.

I believe mine has a 32bit EFI but 64bit cpu ... It's a late 2009 - the one with no built in cdrom and two hdisks. I believe it's the 3,1 so that's cool - thanks!
I don't have access to a supported mac, I do have a vmware install of sierra and I have created a USB installer of sierrra. Is that all I will need or do I need to go and faf more with disk images?

no it's really not - was the early 2009 the 3,1 and the late 2009 the 4,1 ? I know for sure it's not supported - I have a full dev account and it refuses to install.
Just to add the about page shows it's a late 2009, mac tracker doesn't know exactly but the only one in the list is the one I have and that't a 3,1. Yet the official method wont work at all.

The tool will select the appropriate options automatically. Do not install the HDMI Audio patch, as it will disable your audio at this time.

Thanks Dosdude, I'm 99% sure it's a 3,1. I downloaded the update via osx sierra running in a vmware image. I've created a bootable USB, - will that be enough to get this going or do I need to somehow get a hard disk with a working installation of sierra?

What 's the name of the Atheros Wifi card you pointed out?
I am planning to do a MotherBoard swap for my iMac 2007. Do you think a 2008 motherboard for my 20" a good choice?

I've a iMac Early 2008 too. I'm thinking about update it changing the HD with a SSD and the wifi card with BCM4331 to make it compatible with 10.12 and handoff.
