The following file can be added to /etc/sensors.d/applesmc-isa-0300.conf:

chip "applesmc-isa-0300"
	label "temp1" "Ambient"
	label "temp2" "CPU Die"
	label "temp3" "-"
	label "temp4" "CPU Heatsink"
	label "temp5" "CPU Proximity"
	label "temp6" "-"
	label "temp7" "-"
	label "temp8" "-"
	label "temp9" "HDD Proximity"
	label "temp10" "-"
	label "temp11" "-"
	label "temp12" "MLB Proximity"
	label "temp13" "-"
	label "temp14" "MCP Die"
	label "temp15" "-"
	label "temp16" "MCP Proximity"
	label "temp17" "-"

	label "temp19" "-"
	label "temp20" "-"

in order to monitor the hardware sensors on Mac devices running Linux.

In order for Linux to be able to reboot a Mac, the reboot parameter must be set to pci. This can be accomplished by editing either /etc/lilo.conf and adding:

append=" reboot=pci"

Or, for grub, edit /etc/default/grub and append reboot=pci to GRUB_CMDLINE_LINUX_DEFAULT:

GRUB_CMDLINE_LINUX_DEFAULT="reboot=pci"

If the Mac is stuck on a "cannot verify macos" screen that does not allow the user to install the operating system, a trick is to set the date back within 2014. It is possible that either the certificate is too new for the install or that the Apple installer is tied to the create time of the installer itself.
