Alternatives to Multimeter

MacMetra , also on the App Store , opens the developer's site in a new tab MacMetra is a system monitor that lives in the menu bar of your Mac.

A system monitor that lives entirely in the macOS menu bar — no Dock icon, no main window. One compact item shows CPU load, thermal state and memory; you choose which appear and in what order. Clicking it opens a panel with cards for CPU, memory, storage, thermal state and power. It stays inside the App Sandbox, so it shows the four-step thermal state macOS publishes rather than named sensors in degrees, and no fan speeds. No helper tool, no network access, no accounts, no analytics, no history kept. Swift and SwiftUI, universal, macOS 14 or later.

RAMKeeper , also on the App Store , opens the developer's site in a new tab

RAMKeeper is a Mac memory monitor that lives in the menu bar. The free App Store build shows system memory pressure (green / yellow / red) with swap and compressed-memory readings; the free direct download breaks memory down per app and per renderer process and flags hogs such as Chrome helpers, Slack and ChatGPT, with current vs. peak. Pro (one-time purchase) adds threshold rules, Focus Mode to suspend a batch of background apps, and gentle restarts that log the memory macOS actually handed back. No subscription, no ads, no tracking. macOS 12 or later.
