Apple - Can I get the CPU temperature and fan speed from the command line in OS X?
The iStats ruby gem lets you see the CPU temperature via the command-line.
Installation
$ gem install iStats
Usage
$ istats all
Option #1) you may consider using inbuilt utility powermetrics to get the cpu and gpu temperature and lot more other details.
To get CPU temperature:
sudo powermetrics --samplers smc |grep -i "CPU die temperature"
To get GPU temperature:
sudo powermetrics --samplers smc |grep -i "GPU die temperature"
To get lot more details:
sudo powermetrics
This has been tested on macbook pro with macOS mojave.
Option #2) Install Intel® Power Gadget officially provided by Intel from here
Intel® Power Gadget and then launch Intel Power Gadget from the launchpad.
Result Screen:
On BSD systems, the sysctl
utility can provides similar information as the /proc
tree in Linux. It actually report some CPU/GPU temperature information from Xnu CPU Power Management (XCPM):
sysctl machdep.xcpm.cpu_thermal_level
sysctl machdep.xcpm.gpu_thermal_level
However this doesn't seem to be a temperature reading but only an indication of the temperature level compared to some reference.
