MenuBarMonitor
Native for Apple Silicon · macOS 13+

Understand your Mac.
In real time.

MenuBarMonitor puts CPU, GPU, RAM, and thermal status directly into your menu bar. Click once to inspect trends, top processes, and E-core prioritization without root access, tracking, or background gimmicks.

Live in the menu bar

Four live tiles that stay visible without becoming noisy.

CPU, GPU, RAM, and temperature stay in one monochrome line directly in the macOS menu bar. No separate window, no Dock icon, and no distracting alert colors in your peripheral vision.

  • Tile order and visibility can be adjusted with a few clicks
  • Values and icons stay crisp and calm until something truly matters
  • Updates run independently in the background, even while you work elsewhere

P/E core split

See exactly which cluster is doing the work.

Apple Silicon divides CPU load across performance and efficiency cores. Activity Monitor only shows the average. MenuBarMonitor shows each cluster, each core, and live frequency side by side.

  • Per-cluster load in one readable row instead of dense raw numbers
  • Per-core bars make background load and short spikes obvious
  • Current frequency and peak frequency stay visible for both clusters

Memory pressure

Watch real pressure events and free RAM when it actually helps.

The app reads memory pressure directly from the kernel, so you can react before active memory looks full. If you want relief, one click can ask macOS to discard inactive pages.

  • Wired, active, compressed, inactive, and free memory in one glance
  • Largest consumers stay visible so you know who is eating RAM
  • Free RAM keeps authorization persistent after the initial prompt

Mini widget

Pin the same live metrics anywhere on your desktop.

If you want the numbers larger and always visible, the mini widget floats above other windows with the same white-on-dark visual language as the menu bar strip.

  • Always on top and freely positionable
  • Includes the same P/E split used inside the popover
  • Reuses the same metrics engine instead of duplicating CPU overhead

Presets

Configurable

Start with presets, then tune every tile to your workflow.

Every Mac setup is different. Use a sensible preset for day one, then adjust tile order, icons, refresh interval, and language until the layout feels native to your routine.

  • Three icon styles and reorder controls for each tile
  • Refresh cadence for fast render sessions or longer battery life
  • App settings stay persistent across relaunches

No elevated privileges for live readings. RAM relief stores authorization once per session.

Secure by design

If the app does not need a privilege, it does not ask for it.

MenuBarMonitor runs with Hardened Runtime and reads system metrics from public APIs. No debugger entitlements, no process killing, no hidden sudo prompts for live monitoring.

  • Signed build with Hardened Runtime
  • Live readings come from public system APIs that do not require root
  • Memory relief uses a single authorization flow instead of repeated prompts
