I am personally unable to reproduce this issue. Can you share the crash log with us?

There are a few things you can try to try and track down the issue:

There may be some issue with a configuraiton setting or a addon. To test if this is the case, can you load factory settings and test again? To do this:

Select from the top of Blender File -> Defaults -> Load Factory Settings
Then test to see if you can reproduce the issue. Report back with the results.

Do you have any third party apps that interact with your keyboard? If so, can you try closing them and seeing if that stops the crashing?

There is no change with factory settings.
There is nothing interacting with my keyboard. I am using an ordinary qwertz keyboard with windows keys by Fujitsu, not an Apple keyboard.

If I understand the crash log correctly, the crash is occuring when processing keyboard inputs (which is expected based on the information provided). This eliminates other things like add-ons being the cause.

However, I'm not sure how to progress from here because my knowledge in this area of code is limited and I can't reproduce the issue.

@lichtwerk can you test this on your Mac?

Hi, as far as I understand, crash initiated from GHOST_SystemCocoa::processEvents in main thread.
I don't really know much about _CFThrowFormattedException/__NSCFString characterAtIndex. Something related to "string formatting"? Do you use different keyboard layout or language as input?
Have you been experiencing this crash from a long time or started to happen recently (maybe after OS update)?

Still might be better to check with factory defaults: File > Defaults > Load Factory Settings

I have not been using Blender much recently so I don't know at which point this bug was introduced. I know Blender worked fine until some time last year. I just testet the older Blender version 2.79 and now it is also crashing after pressing shift + NumPad. So something else is going on.

I found out that Blender is not crashing when I change the keyboard layout. I am using the attached german keyboard layout. I still think it is a bug because keyboard input should not crash an application.

Using the attached keyboard layout, I can confirm the crash.

I ran a debug build of Blender to see if I could identify the cause, but my knowledge in this area is limited.

[NSApp sendEvent:event]; Error: "-[__NSCFConstantString characterAtIndex:]: Range or index out of bounds"

Looking at the backtrace in the debug build, it seems the issue is occurring inside CoreFoundation, which is a library provided by Apple. And based on the fact the issue is now occurring in Blender 2.79 for you, I would suspect the issue first started occurring after a OS update.

On a side note, the keyboard layout provided can be inspected with a tool called Ukulele. According to Ukulele, when you press Shift + Something on the numpad, nothing is supposed to happened.

And looking at the file directly, no action is defined for shift + something on the numpad. So I'm not 100% sure what's going on here.

Thanks @Alaska . We can ask MacOS maintainers to take a look :)
