macOS 10.12 Sierra Unsupported Macs Thread

After replacing the PlatformSupport.plist and kexts I still get the 'can not' symbol on boot (late 2008 unsupported Air). Is there something I'm missing here?

Try this PlatformSupport.plist. And you're booting a full install, correct (not the installer)?

I have successfully installed MacOS 10.12 on my MacBook 5,2. I installed 10.12 to a second partition running the installer within 10.11.3. I do not have USB is the only issue. If someone can help me solve this I can make a complete tutorial on how to run 10.11 on unsupported Macs without needing an officially supported mac

I am wondering after Sierra was installed on unsupported macs, can they update to smother versions freely in future, say 10.12.x?

Probably not, because you weren't allowed to do so with Mountain Lion and Mavericks. You had to wait OS X Hackers to release a new installer for example for 10.8.4 and then reinstall the OS again.
 
Hi,

as I read my old daily boy (MacBook5,1, Unibody, late 08, Aluminium) is pretty equivalent to the first Unibody MacBook Pro (should be MacBookPro5,5 (13", Mid 2009)) which is supported. I also red about firmware flashes; possible to manuelly flash unpacked ROM from MBP55.00AC.B03 (EFI 1.7) to my one without bricking? Will this override Boardinfo that 10.12 installer will work? Thanks!

Where did you get the info? Cuz mine is "the first Unibody MacBook Pro (should be MacBookPro5,5 (13", Mid 2009)" but isn't supported.
 
Even oracle discontinued public support for java6 3 years ago, hell even java7 has no more public updates.

Forget about java6. Move on to java9 :p
 
Just upgraded my mid 2009 MacBookPro with a SSD and 8Gb Ram, specially for a possible new version os Mac OS. But after seeing the keynote i was a bit disapointed. My MBP isn't supporting MacOS Sierra but a MacBook from the same year does, very disapointing.

But i'm not going to buy a new MacBook Pro just to upgrade to Sierra, i stick to El Capitan.

I feel your pain :( I hate when Apple makes decisions like this. They're a company absolutely rolling in the dough and they can't be bothered.

I was bitten by a similar thing - had just put a new HDD and 6GB of ram into my 2008 White Macbook at the beginning of 2012, only days later to find that Mountain Lion would not support it because Apple couldn't be bothered writing a driver. Had assumed that a machine that wasp purchased less than 3.5 years before-hand would get a few more years of software support.
 
I was initially having issues in successfully booting with the system consistently loading the modified IOUSBHostFamily.kext, however my last system kext cache clearing and rebuilding seems to have finally set things in place.

Odd.

I've a 2008 MacPro that I use to run Server on. I just read the MacOS Server 5.2 beta release notes and Server is supported on Sierra on a 2008 MacPro... but Sierra isn't! How's that for.... well... anyway..
 
Should be similar with a Mac mini Server, I can confirm that Sierra runs on a 2009 (non-server) mini, the only problems right now are USB (which should be fixed, haven't tested yet) and WiFi. The GPU seems to work correctly
 
Yeah speaking of USB. Still having troubles running the installer even with the modified kext. I was on Mavericks, I will load up el cap, disable rootless and see if that helps
