Culpmit

Culprit Limiter for Intel Macs that run hot.

Culpmit sits in the menu bar with the CPU temperature over the fan speed. When something heats the Mac, it names the app and holds it to a share of the processor, so the fans settle and the work carries on.

What it does

  • Readout

    The CPU temperature over the faster fan's speed in the menu bar, live every second; each figure turns orange at its alert's line and red at 90%.

  • Busy apps

    Apps using half a core or more, plus the three holding the most memory, each with a tortoise to cap it and a moon to idle it.

  • Capped apps

    Every app you cap, with every process it starts, held to a share of the Mac from 5% to 80%, beside its memory line.

  • Memory alerts

    When memory used stays past your line, or macOS keeps moving memory to swap, a notification names the heaviest app with Idle.

  • CPU alerts

    At a line you set from 25 to 90% of the whole Mac, held for a minute, a notification names the busiest app with Cap and Idle.

  • Red alerts

    A figure at 90% for a minute brings one more alert while its switch is on; with the switch off, the figure turns red in silence.

  • Heat alerts

    At a line you set from 50 to 90 °C, held for a minute, a notification names the busiest app with Cap and Idle.

  • Test load

    Seven small test apps for one to thirty minutes, so you can watch Busy apps fill, the alerts arrive and Cap and Idle at work.

  • Shrink images

    Each screenshot on the clipboard shrinks to a size you choose, 800 to 2,000 px on its long side, so it pastes light into chats and docs.

  • Clipboard history

    The last ten items, text and images, held in memory; text copied on an iPhone, iPad or another Mac joins the list.

  • Sleep

    Caffeinate on demand, Wi-Fi and Bluetooth off while the Mac sleeps, and a list of the apps keeping the Mac awake.

  • Dev tools

    Every local server listening on the Mac, one click to open, a cap on a next dev run and a switch for the Talk to Figma socket.

  • Touch Bar

    The readout, the switches, the clipboard and a row of apps: a tap does the item's action, a hold opens its details.

  • Everything off

    One click turns every switch and cap off and wakes idled apps; Everything back turns on what was on before.

Touch Bar and clipboard history

The Touch Bar strip: clips arriving and their previews, the readout's details, Shrink, an app's CPU cap and memory line.
Clipboard history in the menu, with two screenshots and two texts.

Install

  • Download

    1. Download the latest Culpmit-x.y.z.dmg from Releases.
    2. Open it and drag Culpmit onto Applications.
    3. Open Culpmit. macOS asks once to confirm an app from outside the App Store: open System Settings › Privacy & Security and click Open Anyway.

  • curl

    curl -fsSL https://raw.githubusercontent.com/booban1/culpmit/main/install.sh | bash

  • Homebrew

    brew tap booban1/culpmit https://github.com/booban1/culpmit
brew install --cask culpmit

    The first open asks for the same one-time confirmation as a download.

Privacy

  • Clipboard history lives in memory and clears when Culpmit quits.
