Sharp Lynx
CPU, GPU, memory & temps — live in your menu bar
Sharp Lynx keeps your Mac's vitals one glance away. Pick the stats you care about and they live in your menu bar, updating every second. Click for a detailed popover, or open the full dashboard when you want the whole picture.
Free · macOS 14 or later · Apple Silicon and Intel · formerly SystemPal
Always on screen
The numbers you actually watch, right there in the menu bar — no window to open, no clicking around.
- Choose exactly which metrics appear, and drag them into the order you want
- Two-line labels so you never have to guess which number is which
- Compact spacing to fit more in a crowded menu bar
- Give the menu bar its own theme, independent of the app
Reorder, relabel, compact
Every chip is optional and reorderable. Build the exact strip you want — a single CPU number, or a full row of CPU, GPU, memory, network and battery.
A dashboard that actually tells you something
Not just a number that goes up and down — the breakdown behind it.
- CPU — live load with a stacked user/system chart, per-core bars split into Performance and Efficiency cores, and 1/5/15-minute load averages
- GPU — utilization and temperature
- Memory — used, plus the App / Wired / Compressed / Free breakdown
- Network — download and upload on opposite sides of the axis, so a busy upload never hides a busy download
- Storage — capacity per volume and live read/write I/O
- Battery — charge, health, cycle count and power draw
- Top Processes — sort by CPU or memory
Dedicated detail pages for CPU, GPU, Memory, Storage, Network, Battery and Sensors, each with a large live chart and the numbers that matter.
A look that fits your desktop
Multi-color (a semantic color per metric), Dual, Mono Amber, Mono Gray, Mono Blue and a clean Light theme. The Mono Gray menu bar adapts to your wallpaper exactly like macOS's own menu bar items.
Thermal sensors and fan speed
macOS doesn't expose thermal sensors or fan speed to sandboxed App Store apps. Sharp Lynx reads them through the free Sharp Lynx Helper, a small companion you download from this page.
The app will prompt you, and can start, stop and update the Helper for you. Everything else works without it.
Private by design
No account. No tracking. No analytics. No network requests. Everything is measured on your Mac and stays on your Mac.
Sharp Lynx is sandboxed with network access switched off, so it cannot make network requests even in principle. Read the Sharp Lynx privacy policy →
Sharp Lynx Helper
Free companion app — only needed for temperatures and fan speed
macOS does not let sandboxed App Store apps read thermal sensors or fan RPM. Sharp Lynx Helper is a small, separate app — Developer ID signed and notarized by Apple — that reads those two things and hands them to Sharp Lynx.
How to install
- Click Download Sharp Lynx Helper above to get
SharpLynxHelper.dmg. - Open the downloaded
.dmgfile. - Drag Sharp Lynx Helper into your Applications folder.
- Launch Sharp Lynx — it will detect the Helper and start it for you. Temperatures and fan speed appear on the Sensors page.
Sharp Lynx can also start, stop and update the Helper from its settings, so you normally won't need to touch it again.

Requires macOS 14 or later. Runs natively on Apple Silicon and Intel Macs. Sharp Lynx is the rebuilt and renamed successor to SystemPal; if you already owned SystemPal, it's the same App Store listing.
