Should be fixed by rBc5fc86117287.

I am still wait for you process for Mac on Blender 2.80 daily build.

Have not confirmed the issue myself, but marking as high priority since this has been reported many times.

This is still a problem with the latest build (edcb5415a275)
Compare latest:
$ find . -maxdepth 3
.
./Contents
./Contents/PkgInfo
./Contents/Resources
./Contents/Resources/2.79
./Contents/Resources/blender file icon.icns
./Contents/Resources/blender player icon.icns
./Contents/Resources/lib

@filip mond (vklidu) (or maybe @Arto Kitula (akitula)), can you check whether this is still the case with current builds? This has been open for a very long time now…

I don't know what to say at this point. Even the basic shaders are not behaving correctly.

Is this still an issue in the latest builds?

I have downloaded the source code and setup the project to compile on my mid 2009 macbook pro (running 10.11.6).

Basically there is a "missing" glFlush (or glFinish) somewhere that seems to create a performance issue on those macs. But without access to the faulty hardware I cannot know where to put it. Or I can put it at random and hope for the best...

@Philipp Oeser (lichtwerk) there are many reported issues like this. All of them seem to be because of buggy/outdated drivers.
I don't think we have a ticket for selection issues like these (at least yet).

Is this still an issue?
I am not sure I understand what you mean by "paint mode preview window" or "preview doesn't show any info at all"

I assume this is still an issue?

To my knowledge, crashes with mesh selection modes and macOS were fixed . If not, we can reopen the report.

As far as I know we worked out known issues with library upgrade. If this is still an issue we need the output from running Blender from the command line to get more clues:
https://docs.blender.org/manual/en/latest/render/workflows/command_line.html?highlight=terminal#macos

A similar bug setting edit selection modes on macOS was fixed long ago, so this should be solved now.

Is this still an issue?

Yes, in mac when changing the resolution also helps. Are the creators going to do something about it?

Alright, not really sure if this will help with MAC, but I had similar problem on my laptop on Windows. I have 4k screen, so I thought that might affect it. After changing my screen resolution in the Intel settings to 1920x1080 blender started running smoothly, just like the 2.79.

Reading through current Blender's 2.80 System Requirements, I am assuming Apple's hardware, while being capable of required OpenGL/OpenCL versions may not meet the required GPU's RAM of 4GB?

@Martin Ackerl (MartinAckerl) are you talking about the last file I uploaded? I’m gonna try it!
Thanks!

@Joan (jbetbe) Probably not a big help, but on my iMac Pro it works if I disconnect at least one other image texture (counting 7 textures).

{F6681180}I see. I tested that first file somebody shared and it worked as @Brecht Van Lommel (brecht) is saying. But what does happen with the other file I shared? (pine) I changed some shaders and reduced image textures nodes to 8 but it's still pink. I know it's maybe not an issue but if is there anyone to help, I'll appreciate it.
Thanks.

There is indeed a limit on the number of image texture nodes that can be used, with the number depending on the graphics card and driver.

I'm having the same issue, here is terminal output. --debug-gpu-force-workarounds didn't help.

Latest beta still crashes in particle edit. 2/20/19

Yes, I can confirm it too, really appreciated! But the issues of pink material persist.
I tried to restart and check it out in my dual boot with a Linux OS but ... the material is pink too. I guess it depends on machine more than OS, right? :(
Thanks!

Thanks @James Peterson (blenderND)
These OpenGL problems on MacOS are really frustrating.

My issues is also resolved with the latest master branch.

Thank you all for your work, it's really appreciated! But unfortunately, even with Feb. 20 version in my submitted file material not updating.blend the material is still displayed in pink.
Or am I doing something wrong? Is there a limit of texture nodes per material on MacOS?

Thanks for testing, let's consider this resolved then.
