Remotely shutting down
There’s essentially two ways to do this from a terminal: sudo shutdown -r now
will reboot the machine, now. Apps don’t get the chance to stop this.
Alternatively, you can use applescript, with commands like:
osascript -e 'tell app "System Events" to shut down'
will shutdown the machine.osascript -e 'tell app "System Events" to restart'
will reboot the machine.
All of these can be halted by other apps, though.
See this stackoverflow answer for other examples.
View Hidden Files in Finder
In a finder or open-file window prompt (using the system control), use command+shift+.
to toggle showing hidden files.
Audio Skipping Glitch
Sometimes, the audio will “skip” when using headphones. Restarting coreaudiod
seems to fix it. If not, then restart the machine and that sometimes helps. This only happens to me after running UI tests in an iOS simulator, or when resetting an iOS simulator.
sudo killall -9 coreaudiod
