The Console app changed fundamentally a few macOS versions ago. Now I can't find my way through it any longer; namely, figure out which log file to look at and how.
Back three months ago, when facing problems with a Time Machine backup disk, I looked harder and found a couple of web pages, ended up with the following instructions for Time Machine, to be used in Terminal:
Stream the log, live (like tail):
log stream --style syslog --predicate 'senderImagePath contains[cd] "TimeMachine"' --info
Don't stream, but show the log end exit:
log show --style syslog --predicate 'senderImagePath contains[cd] "TimeMachine"' --info
I wrote them into a file then, but didn't note or bookmarked the pages where I had found them. Bad idea!
Going through my Safari browsing history for the day at which the file was created, it seems the pages were
If I understand correctly, in the "new" (ie Sierra and above) Console app, system logs are no longer written to a file but are streamed continuously to the app, where they are also mixed with RAM messages. As a result, to consult them and filter those relevant to a particular app or process, you have to use the log utility in Terminal.
It then seems down to finding the correct --predicate option for the problem at hand. I just tried what I could think of for TeXShop, based on the above pages, but it returned nothing, probably because I haven't used TeXshop for several days:
$ log show --predicate 'subsystem == "TeXShop"' --info
Filtering the log data using "subsystem == "TeXShop""
Skipping debug messages, pass --debug to include.
Timestamp Thread Type Activity PID TTL
Log - Default: 0, Info: 0, Debug: 0, Error: 0, Fault: 0
Activity - Create: 0, Transition: 0, Actions: 0
and same with
log show --predicate 'subsystem == "edu.uo.texshop"' --info
What seems needed is to find the relevant --predicate. Is it for TeXShop or pdflatex, namely is it pdflatex which is crashing silently or the communication with TeXShop that does? Based on your log and observation that typesetting does not stop, it seems the culprit is pdflatex.
You might try
log show --predicate 'process == "pdflatex"' --info
but I've no idea whether that would work.
The man page for log has a whole section on predicates:
Using predicate-based filters via the --predicate option allows users to
focus on messages based on the provided filter criteria. For detailed
information on the use of predicate based filtering, please refer to the
Predicate Programming Guide:
The filter argument defines one or more pattern clauses following NSPred-
icate rules. Supported keys include:
eventType The type of event: activityCreateEvent, activityTran-
sitionEvent, logEvent, signpostEvent, stateEvent,
timesyncEvent, traceEvent and userActionEvent.
eventMessage The pattern within the message text, or activity name
of a log/trace entry.
messageType For logEvent and traceEvent, the type of the message
itself: default, info, debug, error or fault.
process The name of the process the originated the event.
processImagePath The full path of the process that originated the
sender The name of the library, framework, kernel extension,
or mach-o image, that originated the event.
senderImagePath The full path of the library, framework, kernel exten-
sion, or mach-o image, that originated the event.
subsystem The subsystem used to log an event. Only works with
log messages generated with os_log(3) APIs.
category The category used to log an event. Only works with
log messages generated with os_log(3) APIs. When cat-
egory is used, the subsystem filter should also be
which is followed by examples.
Not sure the above helps at all. I hope it might.
