@Arto Kitula (akitula) can you see if P486 "fixes" the issue for you?

@Arto Kitula (akitula) will let you handle this one then.

It would have been nice to solve this, but for the next release we will require macOS 10.9 minimum. Apple themselves stopped supporting macOS 10.7 3 years ago.

2x smaller compared to what?

You misunderstood me. The render result is 2x smaller at 1:1 zoom. It has nothing to do with metadata.

Thank you @Brecht Van Lommel (brecht) !

Thanks, I've updated the documentation now, we'll do some further improvements in D2861.

I guess specifically what's missing is that Blender does not support reading and using certain image metadata (like DPI for jpeg).

In the past I had a GTX660 pc card (unflashed) alongside the Radeon original mac card. Now running a (non official) mac flashed Titan with Radeon card.

I don't know why but it wasn't until it was closed until I finally got an email. Thank you, the CUDA driver update did work.

I think this report touches two points. One is the issue introduced since GTAO. The second is the shader version issues.
I'm going to close this now, since those separate and unrelated points are now reported separated in T52593 and T52591 respectively.

I can confirm Eevee seems to be broken in latest master on macOS, after rB659be3876078: Eevee: Rework GTAO.

Thanks for the clarification!

@Matthias Kleinschmidt (matthe) Blender 2.8 requirement still is OpenGL 3.3. What I mean is that if the hardware supports 4.5 it automatically supports 3.3.

According to https://wiki.blender.org/index.php/Dev:2.8/Source/OpenGL minimum requirements for 2.8 should be OpenGL 3.3. In the answer to Andy you mentioned OpenGL 4.5. Did the minimum requirement for 2.8 changed to OpenGL 4.5?

I just tested in @Ton Roosendaal (ton) 's Mac (similar to yours) and I get the same error, even though the NVidia was being used.

I get the same result when I open up the same version of Blender on my max. spec. 5k iMac bought November 2016.

Try to force your NVidia graphic card to be used instead of the Intel: for example using: https://gfx.io
Your graphic card (NVidia) should work - it supports OpenGL 4.5. But be aware that by the time Blender 2.8 is out your computer will already be past the threshold of 5 year old supported hardware.

Same error here… Here some further information:

Yes, that is confirmed, that's why I changed the title.

If you name the file first, then drag the folder, the name you entered gets deleted still.

I can't reproduce this problem, in Blender 2.78c or latest master, with MacBook Pro (Late 2015). I tried zooming all the way in and out in these various editors.

We need someone with OSX laptop around. @Brecht Van Lommel (brecht) assigning to you since you are our main OSX active dev afaik… feel free to resign of course. :)

Please try reinstalling the latest CUDA driver, for some users it appears to get broken after a macOS system update.

Thank you for the report, but 2.8 is currently under heavy development, and we are not taking bugs from end users yet.
Keep watching for updates at https://builder.blender.org/download/ to see if your issue got resolved.

True, aliases aren't supported as they are not posix compilant paths, rather more like hacky bookmarking files. We'll investigate this.
