[Qgis-user] QGIS 2.18.2 Crashes often on Mac (Yosemite 10.10.5)

[John Hawkinson]

I don't have a lot of QGIS experience (none prior to 2.18), and I have seen
more crashes than I would like (mostly related to Cocoa), but I would
offer some general comments:

> I did note this warning there: *WARNING: QGIS will crash if Qt4
> developer components are installed in the standard /Developer
> location. Either rename /Developer/Applications/Qt/Plugins or
> uninstall Qt before running QGIS.*

This is not related. Both because you don't have Qt4 developer stuff
installed, and also because I believe the warning is about a deterministic
crash -- that QGIS will *always* crash if those incompatible components are
installed, not that it will be unstable, which is what you are saying.

There is not enough information in your post to be useful.
You write:

| (I'm not pasting the entire report because it is pretty long):

You should probably get over this, or at least get some background
on what information is important. It is not always the beginning
of the report. It might be helpful to post the report to pastebin.com
or gist.github.com and provide a link, though.

Specifically, when your crash report says:

> Crashed Thread:        18  Thread (pooled)

Then the stack trace for Thread 18 is what's of interest. In your
report, you included only the first thread (Thread 0), and only the
first 11 (0-10) frames of that stack. To be helpful, you should include
the entirety of the stack of the thread in question.
