If you want a Mac menu bar monitor that stays lightweight, readable, and easy to trust, Better Resource Monitor is worth a look.

It is built by Alex Pedersen, and the interesting part is not just that it shows CPU, memory, GPU, disk, and network activity. It is that the product stays disciplined about how it does that.

A lot of Mac monitoring tools drift toward the same tradeoff: more sensors, more panels, more system reach, and often more setup friction. Better Resource Monitor takes a calmer route.

The product positioning is straightforward:

• no root helper
• no private APIs
• sandboxed / Mac App Store-friendly approach
• low enough overhead to leave running all day
• offline by default, with no telemetry requirement

That combination matters more than it sounds.

A menu bar utility is not just another app you open once in a while. It sits in the background all day. So the trust model matters. If a utility is always present, it should be predictable, lightweight, and clear about the privileges it does not need.

That is where Better Resource Monitor stands out.

Instead of trying to become a giant control room, it focuses on the signals most people actually glance at during normal work:

• CPU
• memory
• GPU
• disk
• network

That makes it a good fit for people who want quick visibility when a Mac feels hot, slow, noisy, or unexpectedly busy, without turning the menu bar into a wall of numbers.

The current project materials also make a few concrete claims that are useful when comparing options:

• around 15 MB memory usage
• under 0.1% CPU / energy impact in normal use
• under 7 MB app size
• support for Intel Macs and Apple Silicon Macs on macOS Ventura 13+

Those details will matter to anyone comparing it against heavier menu bar monitors.

It is also worth being clear about what Better Resource Monitor is not trying to be.

If someone wants the deepest possible sensor surface, dozens of panels, or a full diagnostic cockpit, there are other tools aimed at that lane. Better Resource Monitor is more interesting as a practical everyday monitor: lightweight, glanceable, privacy-respecting, and easy to keep installed.

If your preference is "show me the signal without turning my menu bar into a dashboard," this one deserves a look.
