Mnara: Mac menu bar system monitoring app launches on Product Hunt with Apple Silicon limitations
By
Alan MOUHLI
Half-baked but well-meaning. A passing snack.
Summary
Mnara is a Mac menu bar app that provides live system metrics including disk inspection, battery health, startup impact, and network monitoring. The developer discusses technical limitations around CPU temperature estimation and fan RPM access on Apple Silicon (M1-M4), which are locked behind private APIs for sandboxed apps. Real sensor data is planned for v1.5 via helper tools similar to iStatMenus. The app is being launched on Product Hunt with a 30% discount for early customers.
Key quotes
· 4 pulledCPU temperature is currently estimated based on thermal state + CPU load (shown with an 'estimated' label so it's honest).
Fan RPM on Apple Silicon M1/2/3/4 is completely locked behind private APIs for sandboxed apps — Apple locked it tight on M1/2/3/4.
Both real CPU temp and fan RPM are planned for v1.5 via some helpers — same approach iStatMenus uses.
I built Mnara because I was tired of opening Activity Monitor every time my Mac slowed down
