Here's a quick tutorial:
To get a copy of the log, first open the console, from
Applications/Utilities
Once it’s running, you’ll see something like
this (this example is taken after iShowU has recorded some
video):
1. Grab the log starting from the part:
===== Wednesday, 13 September 2006 4:15:33 PM Europe/London
=====
2006-09-13 16:15:37.473 iShowU[2779] [RectSampler] -
Creating a default sampler - through the singleton
2006-09-13 16:15:37.473 iShowU[2779] [RectSampler] - Setup
the default sampler
2006-09-13 16:15:37.561 iShowU[2779] [GLGrabber] - Setup
the GL grabber with 1 displays
...
to where it stops, and include that in your error report.
2. Sometimes you’ll see an error with a number (like
-9405). If you’ve got this, it’s really
important! please make sure to included in the bug report.
