smctemp

Print CPU and GPU temperatures on macOS.

It works on following macs.

• arm64 (M3 mac)
• arm64 (M2 mac)
• arm64 (M1 mac)
• x86_64

Acknowledgements

I took the code from hholtmann/smcFanControl/smc-command and modified it to specialize in temperature acquisition. Some of the sensor values were obtained from the exelban/stats project.
