#83521 — El Capitan worth upgrading?

From	sctvguy1 <sctvguy1@invalid.net>
Date	2015-10-15 17:42 +0000
Subject	El Capitan worth upgrading?
Message-ID	<mvoohv$dgl$1@dont-email.me>

I have an educational iMac/2010, Core2Duo, 2.26, 8gigs of ram, NVIDIA 
9400, no Bluetooth.  I am running ML 10.8.5 at the present time.  Just 
wondering if the new METAL video off-loading will work on this model?  Do 
I have enough RAM?  Will this update improve the performance?

You have enough RAM and 10.11 is faster than previous versions while
still offering more features.

I don't believe Metal support goes back that far though. 2012 comes to
mind?

No, Metal is only on Macs introduced in 2012 or later (excluding the
2012 Mac Pro).

> Do I have enough RAM?

If you have enough RAM now for what you are running, then yes.

The system requirements for minimum memory haven't changed between
Mountain Lion and El Capitan (2 GB). Those who aren't running
particularly memory hungry applications will be fine with 8 GB.

> Will this update improve the performance?

Difficult to predict. Probably similar, or better in some areas but
worse in others.

Some general comments:

Mountain Lion is no longer getting Safari updates and has probably had
its final security update, so staying where you are is increasingly
risky.

El Capitan has just been released, so you might want to wait a few weeks
for the 10.11.1 update so that some early bugs have been dealt with.

We're still in the phase where a fair number of third party applications
are getting compatiblity fixes. In my case, FileMaker Pro 14 just got an
update which fixes the most serious issues with El Capitan, but still
has a few issues which might interfere with work in progress, so I'm not
ready to upgrade from Yosemite quite yet.

is it known if metal will be made to work on older hardware as time goes
by or is aapple doing its usual hardware abandonment program and
continuing to generate landfill

i have been following vulkan and one of the interesting points made by
a couple different people/talks was that vulkan support could go into
even windows xp

the point of xp support wasn't to say that we plan on keeping xp alive but
was to show that the vulkan model is flexible enough that it could even
support xp if someone wanted to do that

older hardware is not capable of supporting metal.

My wife has a 2007 iMac that is running it fine. Well, logging into iCloud
is being weird, but that seems to be a bug others are running into on newer
systems, too.

Try reading more carefully and not snipping too much context.

That comment about the 2007 Mac was in response to nospam saying that El
Capitan (i.e. OS X 10.11) runs on Macs as far back as 2007, not that
Metal is available on Macs that old.

So on the 2007 iMac you mention Metal would not be running at all.  It's 
possibly installed.  It's possibly even loaded.  Just not called to do 
anything related to graphics.  Which means not called at all.

Sorry.  Computers run as programmed.  Not as desired.

My impression was that when running on accepotable hardware, calls to
"Metal" routines would result in a direct interface to the graphics
card. When running on older hardware, calls to Metal routine would be
translated and passed on to older frameworks such as openGL and then
passed on to graphics cards.

But I am sure Rogers, Lewis and their ilk will deny this.

I haven't even participated in this thread until this post, trollbio.

I'd assume that on older h/w Metal is not called at all.

Which means the application needs to have two code branches, one where
it calls Metal and once where it calls older routines, and which branch
is desided at run time where it finds out if Metal is available or not.

It is far easier to just provide a Metal emulation layer by the OS for
older platforms so that apps can just assume Metal is present and the OS
converts Metal calls to older calls transparently.


Are there applications written that require Metal and won't run on older
hardware ? If so, then that would be a sign that a Metal interpretor for
older platforms is NOT present.

No, it doesn't mean that at all.

Of course, the best way to implement such a mechanism would be to do it
in the Cocoa APIs used by applicationsi in a way that is transparent to
developers...

Which is exactly what I am saying. Apps make one Metal call. OS decides
if the call cab be passed directly to Metal-compatible hardware or need
to go though conversion to older API.

Forcing apps to duplicate their graphical code (one for Metal capable
hardware, one for non-Metal) is bad when this could be done centrally in
the OS APIs.

Unless, a decision was made that coding on Metal requires Metal capable
hardware and the app will not launch on onder hardware.

I have no idea which Apple chose.
