Hi Oliver –
I did NOT see this – can you show the URL that you saw this ? This means 5,1 machines or later(6,1 cylinder). Wow.
I am still freaking out that SMB networking is so screwed up in OS X 10.11.5

wow Oliver – you are correct –
if you have a 3,1 2008 or 4,1 2009 Mac Pro – say bye bye !

[Oliver Peters] “In case no one noticed, it appears macOS Sierra will require 2010 machines and newer. This excludes those on 2009 or earlier Mac Pros. I wonder if the next version of X will require Sierra.”

That’s unlikely the case. They no longer support the 2009 Mac Pros, but a firmware ‘workaround’ allows you to make them into a 2010 model.

It should work fine.

[Darren Roark] ” but a firmware ‘workaround’ allows you to make them into a 2010 model”

What’s the workaround?

I believe 2009 MacBooks and iMacs are also OK, based on one article I saw.

[Oliver Peters] “What’s the workaround?”

There is a “3rd party” (hack) firmware installer that allows it to run the faster CPUs and RAM.

There isn’t much difference between a 2009 and a 2012 model once they have the same CPUs and RAM installed.

Thanks. Yes, I’ve been poking around and have seen a few links and the general process.

It’s an easy firmware install to make a 4,1 into a 5,1. Takes 2 minutes. Yes, it’s a hack, but the computers are basically identical, so the 5,1 firmware works fine.

My Mac Pro is a 2009 (4,1) that was a 2.23 GHZ 8 core which is now a 2010 2.93 GHZ 12 core (5,1).
The actual processor upgrade is challenging, but no need to do that if your goal is merely to run macOS Sierra.

[Darren Roark]

I’ve upgraded several 2009s to the 12c 2.93 chips that make it faster than my maxed out 2013.

No Thunderbolt and very limiting what you can add once two double wide GPUs are installed, but for a seven year old computer, wow.

I still like the 2013 better as it doesn’t sound like a wind turbine is in the room with me.

Does this press release address the SMB problem?
