Everybody, I'm currently working on a new tool that automates the process of patching and installing macOS Sierra on unsupported Macs. Should be finished in the next day or so.

Could macOS Sierra be installed on the older unsupported macs? for example iMac 5,1 or Macbook 4,1?
No because their graphics are completely unsupported by OS X. There were never any 64bit drivers written. Those also have a 32bit EFI so even if you could install Sierra it requires more hacking, like the MacPro1,1/2,1. The difference with those is you can upgrade the GPU.
This won't happen for a while since we are focusing on supported Macs right now. @dosdude1 gave me an idea to solve the SIP issue with the unsigned kexts without rewriting the Bootloader. I would still need time to makes some changes to the USB Kexts and Graphics Kexts to get it up to the Yosemite quality performance (without Graphics Acceleration) we have now with MCPF and OSXE.
Those models have 64bit architecture they just don't have it graphics wise since Apple dropped the kexts in OS X 10.6.2.
Hey, Small world.
Lots of theese macs using Merom. Currently Sierra requires CPU with SSE4.1 instructions like Penryn or newer.
The MacBook 4,1 has a 64-bit EFI if I'm not mistaken. It was dropped in Mountain Lion because of the GMA X3100 iGPU.
You are correct, it does. The iMac mentioned does not. Still need graphics drivers though.
Yep but I believe the MacBook 2,1 - 3,1 and iMac 5,1 are Merom which I unfortunately had to drop in OSXE1.33. I question how we are able to even get Yosemite running on them at times.
That is true. My iMac 6,1 (24" version of 5,1) can run El Capitan with the same boot.efi replacement the Mac Pro 1,1 requires, but the issue is graphics. There are no kexts for the GeForce 7600 GT. That pretty much forces me to keep it on Mountain Lion.
I've just finished the automated tool. It may still have some bugs, but if people could test it out for me, that'd be great!

Looks good. I'm testing it out now.
EDIT: Correction needed as shown in previous post.
Alright, should be fixed now. Go ahead and give it a shot. Note that after the install completes, you'll need to run the post install utility, which is located under the "Utilities" menu in the OS X Installer.
EDIT: Still doesn't seem to be working.

Alright, the automated patcher is now complete, and SHOULD work perfectly fine. Here's how to use it: First, browse for your copy of the macOS Sierra installer app. Second, select your USB drive that you want to use to install macOS with, and click Start Operation. When the tool finishes, boot it on your unsupported Mac, and install normally. After the installation completes, boot back into the installer, go to the Utilities menu, and select "macOS Post Install". Select the drive on which you just installed macOS, and click "patch". You should now have a working system, with the exception of WiFi on some systems. http://dosdude1.com/sierra/macOS Sierra Patcher.zip
