on 10.9 and earlier, it is a dictionary rather than an array. I will try later
today to see if there is a better way to enumerate the power sources.
I can't test this easily on 10.10 (my 10.10 box is powered by a serial UPS
that does not show up in Energy Saver), but it uses the proper API now, and
works on 10.9.

I pushed the branch as macosx_power_dict:

https://github.com/networkupstools/nut/commit/b608975b55895e853ba8d24fc08761bff2c65940

Patch: https://github.com/networkupstools/nut/compare/macosx_power_dict.diff

I don't use MacPorts much, but I think this is how you would add this patch
to the NUT portfile:

Thank you. Does not give any errors, seems to run. Will try with upsd next.

[Nut-upsuser] Driver macosx-ups failing on Yosemite

Driver is working, but high CPU use-

process		cpu%	cpu-time	threads	wakeup	pid	uid
 macosx-ups	100.0	26:50.99	1	0	70413	_nut	

99% to 100% CPU use, > 26 minutes runtime

This does not seem right.

Thanks

[Nut-upsuser] Driver macosx-ups failing on Yosemite

I think the high CPU usage was caused by the native OS X driver crashing and not
working properly. The native driver was not sensing the UPS going on battery or
any change in battery percentage. Unplugging the USB and then plugging it back
again made the native driver come back up again properly. Restarting the
macosx-ups driver seems to get back to normal CPU usage. I will monitor and see
how it goes, but it seems the native yosemite driver is flaky. Or maybe the UPS
is flaky. Will monitor and see how it goes. May have to attach the UPS to the
linux machine and use the mac as a client, however it is easier to use the mac
with the native control panel if the native driver works OK.

As you can imagine, if the native driver does not see a change, the macosx-ups
driver will not, either. Unfortunately, there is no timestamp on the data from
the OS, so I am not sure if there is anything we can do to detect that
condition.

If you do see 100% CPU usage on the NUT driver in the future, I would be
interested in seeing a profile sample to see where it is spinning. Activity
Monitor -> CPU tab; click on the process, and under the gear icon, choose
"Sample Process".

Another potential problem that you might see is that the driver will trigger an
assertion and exit when the UPS is unplugged. Theoretically, this could be fixed
with a launchd plist that restarts the driver, but the usual way to handle this
in NUT is to mark the data as stale, and wait for the UPS to reappear. (Does
MacPorts use a launchd plist?)
> May have to attach the UPS to the linux machine and use the mac as a

native driver works OK.
Something that has been on my TODO list for a while is a System Preference pane
for NUT that would connect out to upsd running on another system, and present a
virtual UPS object to Mac OS X. GUI programming is not my forte, but if you know
anyone else interested in making this happen, let me know.
