What you need to do this first: Move the zip file from the USB drive to the desktop. Use Disc Utility to format the USB drive (HFS+ journaled). Launch the app inside the zip file after the zip file (another window will appear) has been opened. Just follow it's directions. Dosdude1 made the app so easy to follow.
Well, my mid-2009 polycarbonate MacBook doesn't meet the requirements. But I'll still be using it for some time until I replace it with a new Mac laptop (probably a 13" MacBook Pro, either "regular" or Retina Display).
But my 2012 Mac Mini makes the grade!
I'll be looking into either a 2012 or 2013 MacBook Pro 15 inch from eBay for my main portable after Sierra is released to the public.
Even though my MBP late 2008 can run Sierra by using dosdude1's tool, I want stability in the long run. Throughout the beta process, I'll be having fun testing Sierra on my MBP late 2018 (5,1).
There's no reason to run El Capitan on a 2008 or older MacBook, or 2006 iMac or MacBook Pro, as the GPU isn't supported, which would result in extremely terrible performance, as well as functionality limitations.
Terrible performance, yes. But, using the experiment SL 64 bit kexts in Yosemite, I was able to even edit video in Adobe Premiere. They still serve a purpose. Even if it's to just say you did it. So. Is it possible?
I've kept both my late '07 Macbook and my late '06 iMac at Mountain Lion, which remains a reasonably current OS and runs well on them.
Running something newer is technically possible, but even Mavericks is a pig.
It's something like my AIO G3 that I'm going to get Leopard running on sometime this week. I have a pre-made install image with the correct kexts installed a friend gave me to make it function, and the G4 upgrade I just installed makes it technically possible(once I actually get the computer booting on the G4 ). Even so, it's an intellectual exercise as the Rage graphics really are a pig in Leopard. Transplanting the kexts from Tiger does wonders, but it's still underpowered for an OS designed in the Intel era.
Simply dropping in the 32-bit kexts from Snow Leopard or Lion doesn't work, the only option is to upgrade the GPU. I am wondering how that is possible on a Mac mini though...
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.
MacBook (late 2009 or later)
iMac (late 2009 or later)
MacBook Air (2010 or later)
MacBook Pro (2010 or later)
Mac mini (2010 or later)
Mac Pro (2010 or later)
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.

That's because you probably used the HDMI audio patch. To remove it, run these commands in Terminal: "sudo rm -R /Library/Extensions/LegacyHDMIAudio.kext" and "sudo kextcache -system-prelinked-kernel".

I figured out why the kext breaks audio on laptops. It is set to apply across ALL devices with vendor ID of nvidia. But, on nforce chipsets, that includes a lot of irrelevant devices like the AHCI controller, which totally confuses Apple's audio drivers.
Can someone link the firmware upgrade to go from a Mac Pro 4,1 to 5,1? I'm considering buying a 4,1 on the next few days. Wanted to do a 2,1 but doubt they'll be supported.
At this point, not a chance on the 2,1 since they don't support the required instructions.
More than a few of us are running 1,1s that are effectively 2,1s-mine is on the 2,1 firmware with X5355 processors(standard on the 2,1, not supported by the 1,1).

Yes, they will.

I'll probably try at some point to patch the recovery partition. Didn't bother with it right now, as I found it somewhat unnecessary.
Assuming we have an update tomorrow, what will the process be? Do you know already? Your patch worked like a charm but I'm not sure what to expect for the next update since it looks like it will need to be patched as well. Will this be the full process again of downloading the full 5GB file and the patch and installing again or will we just upgrade?
Thanks again. 2009 MacBook Pro everything works like a charm. (Minus recovery partition but not a huge deal)

My assumption is that, once Beta 2 is installed, you'll simply need to run the post-install patch again. If that ends up not being the case, I'll be sure to update the tool.
thanks to 2dosdude1, me finally manage to install the new OS into my unsupported MacBook pro mid 2009 after following your instruction. but one thing I would like to find out, after me installed the new OS, the MacBook pro seems like a new set....all my music in iTunes, photos is gone. I got an external HD which I backup before I installed but seems like the new OS time machine can't seems to restore to the latest backup? How do I get the music and photos back?

You formatted your hard drive, just copy back the stuff you lost from your backup. I wouldn't recommend using this as your main OS at this point, though, as it's in very early beta stages.
ok....so which mean I can't use time machine to restore to the latest backup? does this mean if beta 2 is out, I will need to repeat all the process again?

From what @dosdude1 said in the past, you should be able to just upgrade normally through the app store and then apply the patch from the USB stick you used to install beta one. Hopefully it works out, we shall see tomorrow! (i think)

which is the best way to copy or transfer the old backup files to the new OS? Can I use Migration Assistant? not only the files I want to transfers. I want to transfer everythings like apps, songs, photos.....etc from my old OS to the new OS. And if I remember correctly, when I click on the time machine, it doesn't show the latest backup date. is this normal? I remember in the previous OS, it did show.

I have the same system, all works great except recovery partition - but it seems that you can mount it with a program like Mountain and edit the plist file...going to try it now and will report back
