MACOSX-UPS(8) NUT Manual MACOSX-UPS(8)NAMEmacosx-ups - monitor for Mac OS X built-in UPS and battery driver
NOTE
This man page only documents the hardware-specific features of the
macosx-ups driver. For information about the core driver, see
nutupsdrv(8).
SUPPORTED HARDWAREmacosx-ups supports any USB HID Power Device Class (PDC) UPS which is
matched by the Mac OS X built-in drivers. It also can monitor a laptop
internal battery as though it were an UPS.
If the UPS is visible in the Energy Saver preferences pane of System
Preferences, this driver should be able to monitor it.
EXTRA ARGUMENTS
port=regex
The port parameter in the configuration file can be a
case-insensitive extended regular expression (see regex(3) for
details) to match against specific UPS and battery names.
The traditional NUT auto-detection value of "auto" will be changed
to "/UPS". To test this driver against the internal battery of a
laptop, a value such as "battery" can be used.
model=regex
Likewise, if you have more than one UPS, it may be necessary to
specify a model name to match against. This parameter is also a
case-insensitive extended regular expression.
DIAGNOSTICS
If the driver cannot find an UPS, first open System Preferences and see
if there is an "UPS" tab on the Energy Saver panel. If so, re-run the
driver with the -D flag to list the names of the power sources found.
KNOWN ISSUES AND BUGS
This driver is a monitoring-only driver, and cannot shut down an UPS on
its own. However, this should not be a problem in practice: it is
monitoring the built-in Mac OS X UPS driver, which has configuration
options for several shutdown scenarios. Consult the Energy Saver
control panel or pmset(8) for more information.
The default distribution of apcupsd installs a kernel extension which
prevents Mac OS X from attaching to the UPS. In order to use this
driver after installing apcupsd, you must first run the
apcupsd-uninstall script and reboot.
Note that other UPS monitoring solutions may show more detail than what
is provided by the built-in Mac OS X driver. In particular, voltages
other than the battery voltage, as well as current and frequency, are
typically not shown. It may be possible to monitor these values with
apcupsd (for APC hardware only) or usbhid-ups(8).
