Wake On Lan, I tested with a small Fujitsu Esprimo mini computer and a Mac Mini.
In a Windows desktop app "WakeMeOnLan" on another unrelated computer, I can see "green" dots for awake clients, and "red" dots for sleeping clients. I can put the Esprimo to sleep, so the dots turn red, but not the Mac Mini. How can I test if my Wake On Lan works?
Esprimo with Ubuntu
- makes a "click" noise when switched on, so I know it worked.
- The colored app indicators change between green and red, as expected.
- SSH connection drops on sleep via
Mac Mini with latest OS
- LED stays on always
- Monitor turns off when starting sleep via SSH and
- Even after
sleepnow, the colored app indicators are always green (unless the Mac is really switched off, so I can't wake on lan anyway)
- SSH connection stays alive
- After some time of inactivity the MAC's LED pulsates slowly, which at least gives an indications of a changed state. Still, the colored indicator in my wake-app is still green not red.
With the mac I have tested hibernate modes 0,3,25. Energy saving settings are those:
- [ ] Prevent computer from sleeping automatically when the display is off
- [X] Put hard disks to sleep when possible
- [X] Wake for Network Access
- [X] Start up automatically after a power failure
- [ ] Enable Power Nap
How can I be sure that the Mac is sleeping actually? (LED, SSH connection,...) I need a way to proof that my Wake On Lan actually works for the Mac. It might just be a typical Mac issue, but I have no clue about Apple stuff.
