a nudge at shutdown when your magic mouse is running low,
so it charges overnight.

why

the magic mouse charges through a port on its belly, so you can't use it while it charges. the only good time to plug it in is when you're done for the day.

which is exactly when you forget.

then it dies at 10:14 the next morning, halfway through something.

what it does

when you shut down, restart or log out, it checks your mouse's battery. if it's low, this shows up for four seconds:

A black card reading: charge your mouse. 8%, with a mostly empty battery bar. Plug it in now so it's ready next time. Click or press any key.

then your mac carries on shutting down. click or press any key to skip the wait.

details

footprint

measured on a running copy, 40 minutes in:

cpu
~0%. 0.2 seconds of cpu time in 40 minutes.
memory
~21 MB.
battery
reads the level every 10 minutes from what macOS already knows. it never wakes the mouse, so it doesn't drain it.
network
none.

install

  1. download and open ChargeYourMouse.dmg.
  2. drag charge your mouse into applications.
  3. open it once. from then on it starts with your mac.

the app isn't notarized by apple, so the first time macOS won't open it. go to system settings → privacy & security, scroll down and click open anyway.

change or remove

open it again from applications or spotlight to change the threshold, turn off open at login, or uninstall.
