Time Machine

Apple’s Time Machine is a neat little utility to automate onsite backups. However its machinations are, like so many of Apple’s products, completely opaque to the end user using the standard user interface and so troubleshooting can be rather difficult. Fortunately for us, this is one of those circumstances where Terminal commands can come to the rescue.

Our first magic spell is…

log show --predicate 'subsystem == "com.apple.TimeMachine"' --info

This will show logged message from the past and can be useful if you’re trying to troubleshoot an issue that’s already in progress. Run this command and macOS will display the last few weeks of Time Machine logs before exiting

The second magic spell is…

log stream --style syslog --predicate 'senderImagePath contains[cd] "TimeMachine"' --info

This command will run – and will remain running until you explicitly exit it – and will display any log messages that Time Machine writes out to the system log.


Huzzah! NetNewsWire – the first RSS reader that I ever really used in anger – is back as a modernised and updated open source project! A lack of external sync services marks it out as still quite far from a usable initial release, but, as soon as some of these are added I shall look at moving away from the moribund Reeder and back to NNW as my desktop RSS reader of choice.

Now all we need is for Google to retask the now defunct Google+ team to resurrecting Google Reader and we can all start RSS’ing like it’s 2007 again! After all, without Google+ (or a similar replacement), there is no need for Google to try and kill off the open web in favour of their own walled garden.

(And for anyone searching; the new NetNewsWire agent string is “NetNewsWire (RSS Reader; https://ranchero.com/netnewswire/)”)
