Sudoless utility to profile current frequency, cycles, voltage, residency, and more on Apple Silicon!
- Table of contents
SocPowerBuddy samples counter values from the IOReport and returns formatted results for various metrics! It's written in Objective-C because NS types made things easier, it could be better if I rewrote it in plain C (but I've got better projects to work on then to spend time on this one).
It is based on reverse engineering powermetrics, and reports every statistic offered by powermetrics -s cpu_power,gpu_power (see full metric list and example output), but without needing sudo! I've also added some added some other metrics, like per-core power and voltage 😄
Please check compatibility with your silicon before use, If you want a good experience (see compatibility notes)
Because needing to be system admin in order to monitor Apple Silicon frequencies is dumb (yeah, I'm looking at you, powermetrics). So here you go! No administrative privileges needed! Yaaay.
Note: The following is a big, nice, juicy output of socpwrbud -a running on a Macmini9,1 (cause I'm a pleb who didn't buy a M1 pro).

The following is sampled per-cluster and is available for all sampled compute units!
- CPU/GPU
- Active and Idle Residencies
- Active Frequencies and Voltage
- DVFS Distribution and Time Spent
- Power Consumption
- CPU Only
- Total (cluster) Instructions Retired and Per-cylce
- Total (cluster) Supposed CPU Cycles Spent
- Per-core metrics
- Micro architecture names
I would love to support ANE stuff too but thats just a false dream encouraged by compiled remnants in powermetrics...
Note: Tool usage is listed by socpwrbud --help!
- If you dont have Hombrew, then what the heck? Install it already, geez.
- Add my tap using
brew tap dehydratedpotato/tap - Install the tool with
brew install socpwrbud - Run
socpwrbud! (dont ask why "power" is shortened for the binary name)
- Download the bin from latest release.
- Unzip the downloaded file into your desired dir (such as
/usr/bin) - Run
socpwrbud! (still, dont ask why "power" is shortened for the binary name)
Xcode proj is in source but you can build with make if you so desire...
This project has recently influenced the CPU/GPU power related metric gathering on NeoAsitop! Yay! Go check it out ❤️
Here's a sick table. Depending on what Apple decides to break, it doesn't mean anything. How cool is that?
| Silicon | Codename | Support Status |
|---|---|---|
| M1 | t8103 | Fully working |
| M1 Pro | t6000 | Works (But no tests for binned 8-Core model) |
| M1 Max | t6001 | Fully working |
| M1 Ultra | t6002 | Should work maybe? (see #5 and patch v0.3.1) |
| M2 | t8112 | Should work? |
| M2 Pro | t6020 | i dont know man |
| M2 Max | t6021 | like for real |
If any bugs or issues are found, please let me know in the issues section. If the problem is related to missing IOReport entries, please share the output of the iorepdump tool found in the latest release. Feel free to open a PR if you know what you're doing 😄
