Want to study file, process or network events in macOS? Crescendo is the tool, for Catalina. It’s free and open source too.
One small change: you no longer need to press Tab or Enter to set the time period.
Now feature-complete, this version has powerful tools to help you locate significant events to the second and better.
Now collects log entries reporting progress and rates of transfer during a backup, and giving info on what is slowing them down.
How can you tell what causing a backup to run so slowly? If it is this bug, what can you do about it? A plain user’s guide.
Surely these problems with Time Machine are old hat and not news? Or are they simply errors occurring with disks or the file system?
Here’s what happens when a Time Machine backup, normally the first, slows to the point where it’s just never going to finish.
Logs are normally backed up by Time Machine, but Apple provides no tool which can access those backed up logs. Here’s how to do it.
The more frequently your Mac writes entries to its log, the shorter will its log record be: anything from a couple of days to almost a month.
If a Time Machine snapshot can’t be thinned, nothing warns you of the problem, and without Terminal or the log you can’t even find out.
