[Bf-committers] Mac OS 10.7+ for Blender 2.8

[Mike Erwin]

Ok, I've had a chance to read your points and dig up the hardware facts.

I was concerned about the people that are stuck on 10.7 because their
computer can't support 10.8, and didn't want us to leave them behind
without a very good reason. Other people/projects/companies abandoning it
are not good reasons. But...

The only Mac than could run Blender 2.8 but not OS 10.8 is the first Mac
Pro (Aug 2006 - Jan 2008), and only with an upgraded GPU. iMacs, MacBooks
Pro, everything else of that era is stuck with an old GPU and won't be
supported anyway.

So now we know exactly who we'll be disappointing! Mac Pro owners (early
adopter or second-hand) that don't have a newer Mac to run Blender on.
Seems like a very small segment...

Any newer Mac running 10.6.8 or later can upgrade to 10.9 free of charge.
Nobody is "stuck" on 10.8 by hardware. They might choose to run 10.8 or
(god forbid) 10.7 but we have no obligation to support their choice.

After gathering these facts I am also in favor of making Mac OS 10.9 the
new minimum.
