macosx-ups \- monitor for Mac OS X built\-in UPS and battery driver
.SH"NOTE"
.sp
This man page only documents the hardware\-specific features of the \fBmacosx\-ups\fR driver\&. For information about the core driver, see \fBnutupsdrv\fR(8)\&.
.SH"SUPPORTED HARDWARE"
.sp
\fBmacosx\-ups\fR 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\&.
.sp
If the UPS is visible in the Energy Saver preferences pane of System Preferences, this driver should be able to monitor it\&.
Likewise, if you have more than one UPS, it may be necessary to specify a
\fBmodel\fR
name to match against\&. This parameter is also a case\-insensitive extended regular expression\&.
.RE
.SH"DIAGNOSTICS"
.sp
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 \fB\-D\fR flag to list the names of the power sources found\&.
.SH"KNOWN ISSUES AND BUGS"
.sp
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 \fBpmset\fR(8) for more information\&.
.sp
The default distribution of \fBapcupsd\fR 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\&.
.sp
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 \fBapcupsd\fR (for APC hardware only) or \fBusbhid-ups\fR(8)\&.
