macOS Hardware Stats

Get CPU & GPU temperatures and fan and battery statistics from your Mac.

This simple script will output a JSON array containing hardware statistics from your Mac.

Prerequisites

• Install sensei. brew install drpsychick/sensei/sensei
• Install the smc binary.
  • Method 1:
    • Copy the smc file to /usr/local/bin or your preferred location. You can specify the path with the --smc-path argument.
    • Run chmod +x /usr/local/bin/smc
  • Method 2:
    • Compile smc from the included source (original source here):

      cd ./smc-command_src
      make
      make install

Usage

./stats.py [-h] [--collection {all,temps} | --component {cpu,gpu,fans,battery} --fan {0,1}] [--smc-path SMC_PATH] [--sensei-path SENSEI_PATH]

Argument	Description
-h, --help	Show help message.
-l, --collection	The collection to query. Defaults to all. Collections: - all: Query supported statistics. - temperatures: Query all supported temperature statistics.
-c, --component	The component to query. Components: - cpu: Query supported CPU statistics. - gpu: Query supported GPU statistics. - fans: Query supported fan statistics. - battery: Query supported battery statistics.
-f, --fan	Fan number to query. Can ONLY be used with '{--component,-c} fans' argument. Defaults to all. Fans: - 0: Left - 1: Right - all: Query all fans.

Example: ./stats.py
Output: {"cpu": {"temperature": 76.9}, "gpu": {"temperature": 69.0}, "fans": [{"current_speed": 4437.0, "current_speed_pct": 60.4, "min_rpm": 2160, "max_rpm": 5927, "side": "left", "id": 0}, {"current_speed": 4079.0, "current_speed_pct": 59.5, "min_rpm": 2000, "max_rpm": 5489, "side": "right", "id": 1}]}
