$ timedog
None or only one Time Machine backups found at /usr/local/bin/timedog line 184.

# Note: "-m" switch isn't supported

Usage: tmutil listbackups

I'm not sure why timedog uses an -m switch/argument, but it seems that's not supported on (older?) versions of tmutil (e.g. under 10.10.5 Yosemite) and hence breaks things. After I fix it up it seemingly works again.

$ sudo sed -i -e 's|tmutil listbackups \-m|tmutil listbackups|g' /usr/local/bin/timedog

Thank you for the report. I'll try to track down when this option came into being and see if can be gated on the macOS release. Which macOS release are you using? It is 10.10.5?

@nlfiedler Yes, 10.10.5 (last update was in 2017? :) ). The available tmutil looks "a bit" older at least:

$ tmutil --version
tmutil version 3.0.0 (built Dec 11 2014)
