This should be solved now with the continuous grab fixes.

The Blender internal BVH builder is running out of stack space, it might be macOS specific since threads there have a smaller default stack size than other operating systems.

Crash confirmed.

Oh, did not saw latest comment… so crash can be replicated, and seems to be a Cycles issue, OSX-only maybe?

I could test it with a gaming mouse now and the issue is much worse then. I found a fix now, mouse motion should be always smooth now, both for gaming mouse and heavy scenes and other mouse.

@Andrei Nadin (AnadinX) No problem. I am glad it worked for you too :)

@Chris Williamson (chris) Slazinski (mallow) indeed it is, big apologies I had not seen you comment when I came across this problem before.

@Andrei Nadin (AnadinX) Isn't this the same as my fix?

Pretty good fix here for it.

No reply over a week so closing for now.

Yes sorry I am running OSX 10.12.5

As user I would like to keep simple way, so I'm ok with the .dmg solution.

+1 for signed .dmg

Ok, the fix might be so simple, but some possible solutions:

• Put blenderplayer in blender.app/Contents/Resources/
• Distribute blender as a signed .dmg

Gatekeeper translocation copies .app to folder under /private/vars/folders. That is, quarantine location. We don't know what is the location where blender was copied.

Surely this is still a bug and something we can fix quite easily?

MacOS Sierra has system called translocator. This messes up bpy.app.binary_path.

You didn't specify macOS version.
Nevertheless, take look at T51808

the Base Installer fix my problem, thank you very much

When try to open 2.78 in terminal with sudo, it returns following text:
blender(1052, 0x7fffe18f23c0) malloc: * error for object 0x10e261fc0: pointer being freed was not allocated
set a breakpoint in malloc_error_break to debug
[1] 1051 abort

@wky (bolt2009), did you try the solution suggested here, upgrading the CUDA driver?

I have same issue, the 2.78C and 2.79 keep hang on when start up everytime, Imac with latest iOS, the situation starts when I upgrade blender to 2.78(on 2017.06.10) and open a blender file (download from bt, its a file create on 2015)
I try to use 2.77 and work 3 days until 2017.07.12 afternoon, when I click the world icon it crash...and keep crashing that way...
My client will be mad soon..

I made a quick screen capture on this: link to youtube

I can kind of reproduce this, when working in a heavy scene. In that cases the mouse cursor only moves when Blender redraws, and feels quite jumpy, though I'm not sure what's being described in this ticket. Sometimes the mouse position goes out of sync with object being dragged.

Please can you specify the Blender's version you are trying to install, specific hardware?
Does a developer build from https://builder.blender.org/download/ (from the first section at the top)
work for you?

I too can confirm that placing Blender.app directly in /Applications solved the issue with a duplicate icon appearing in the dock. One solution besides creating a .dmg installer could be to have Blender.app placed alongside (instead of within) the folder that contains the licenses and extras (such as Blender Player). That way when users drag it to /Applications it's exactly where it needs to be from the start. Just an idea.

I can confirm this issue. When continuous grab is enabled, rotate, pan and zoom behaves erratically. Once it's disabled, it's smooth again.

No reply over a week therefore closing the report for now.

Ah. Having CUDA on non-nvidia platform is quite uncommon :)
But good to know, as there might be people using thunderbolt-pci chassis.

UPDATE: I just got it working. I updated my CUDA drivers and it loaded without a hitch.

Probably some issue with opening URLs for some reasons… anyway, since it now works, we can close, thanks for the report. :)

It works now. Thanks!
