Sort of. It provides detailed technical information about the current
state of the application when the crash occurred, and the technical
reason for the crash (which is almost always a memory access violation).
This can be used by the author of the application to track down bugs,
but apart from some general clues there isn't usually much that an end
user can do with it.
On rare occasions it might give you enough information to identify
something which you can avoid doing in future to prevent further
crashes, but you may need a high degree of technical knowledge (or
assistance from someone else here) to be able to draw this sort of
conclusion.
So my questions are, and please make allowances for a Mac newbie.
1. Does every program have its own log file?
The system creates a separate "crash log" file for each application,
which records details about each time that application crashed.
(It actually maintains a set of these for each user account, so the
crash log you see will only record crashes that occur when you were
running an application, not while another user on the computer was
running the same application.)
2. Is every time the program is called into use appear on the log?
There isn't a general log which tracks normal use of each application.
3. Are all the logs located in the same directory, and if so where is
it?
The best way to see them is to use the Console application, which is
located in /Applications/Utilities. It lets you browse through all
available logs on the computer in a reasonably safe and easy to use
manner.
The crash logs are stored here:
~/Library/Logs/CrashReporter
(That's the Library folder inside your home folder.)
There is a separate file for each application, which has the name of the
application followed by ".crash.log" (or sometimes just ".crash"). They
are plain text files.
Console also shows you lots of other logs. The ones of main interest are
the "Console log" (described as "Console Messages" under the "LOG
DATABASE QUERIES" heading in 10.5) and "system.log".
The Console Messages log contains diagnostic messages output by many
applications, which are sometimes useful in getting clues about
problems. system.log contains similar information, sometimes in greater
detail.
I have been having a lot of trouble with Safari 3.1.1 running under
10.5.3 on an Intel mini. It doesn't exactly crash. It just sort of
becomes increasingly non-functional. For example, it will not give a
link cursor for a known link, and if I click the link anyway, it does
nothing. When I try to quit it - it won't. I have to force quit it.
It doesn't say anything like non-responding in the force quit panel. I
have tried to find a log and send it to Jolly Roger, but I can't find
anything in the logs. Any ideas?
TIA
